Abstract
We report findings of strong anomalies in both mutual inductance and inelastic Raman spectroscopy measurements of single-unit-cell FeSe film grown on Nb-doped SrTiO3, which occur near the temperature where the superconductinglike energy gap opens. Analysis suggests that the anomaly is associated with a broadened ferroelectric transition in a thin layer near the FeSe/SrTiO3 interface. The coincidence of the ferroelectric transition and gap-opening temperatures adds credence to the central role played by the film-substrate interaction on the strong Cooper pairing in this system. We discuss scenarios that could explain such a coincidence.

Abstract
We have developed a bilayered dermal-epidermal scaffold for application in the treatment of full-thickness skin defects. The dermal component gels in situ and adapts to the lesion shape, delivering human dermal fibroblasts in a matrix of fibrin and cross-linked hyaluronic acid modified with a cell adhesion-promoting peptide. Fibroblasts were able to form a tridimensional matrix due to material features such as tailored mechanical properties, presence of protease-degradable elements and cell-binding ligands. The epidermal component is a robust membrane containing cross-linked hyaluronic acid and poly-l-lysine, on which keratinocytes were able to attach and to form a monolayer. Amine-aldehyde bonding at the interface between the two components allows the formation of a tightly bound composite scaffold. Both parts of the scaffold were designed to provide cell-type-specific cues to allow for cell proliferation and form a construct that mimics the skin environment.

Abstract
Correlative light and electron microscopy (CLEM) is one attractive method of observing biological specimens because it combines the advantages of both light microscopy (LM) and electron microscopy (EM). In LM, specimens are fully hydrated, and molecular species are distinguished based on the fluorescence colors of probes. EM provides both high-spatial-resolution images superior to those obtained with LM and ultrastructural information of cellular components. The combination of LM and EM gives much more information than either method alone, which helps us to analyze cellular function in more detail.We propose a Y2O3:Tm,Yb phosphor nanoparticle which allows upconversion luminescence (UCL) imaging with near-infrared (NIR) light excitation and cathodoluminescence (CL) imaging [1], where the light emission induced by an electron beam is called cathodoluminescence (CL). Due to electron beam excitation, the spatial resolution of CL microscopy is on the order of nanometers [2,3]. Upconversion is a process in which lower energy, longer wavelength excitation light is transduced to higher energy, shorter wavelength emission light. So far, in LM observation for CLEM, ultraviolet (UV) or visible light has been used for excitation. However, UV and visible light have limited ability to observe deep tissue regions due to absorption, scattering, and autofluorescence. On the other hand, NIR light does not suffer from these problems. Rare-earth-doped upconversion nanophosphors have been applied to biological imaging because of the advantages of NIR excitation [4].We investigated the UCL and CL spectra of Y2O3:Tm,Yb nanophosphors. Y2O3:Tm,Yb nanophosphors that emit visible and near-infrared UCL under 980nm irradiation and blue CL via electron beam excitation. To confirm bimodality of our nanophosphors, correlative UCL/CL images of the nanophosphors were obtained for the same region. The nanophosphors were poured onto a P doped Si substrate (Fig. 1(a)) and were irradiated with 980 nm NIR CW laser light or an electron beam. Fig. 1(b) shows the UCL image of the nanophosphors under 980 nm NIR CW laser irradiation, UCL spots were observed, but the individual nanophosphors in each spot were difficult to distinguish in the UCL image. On the other hand, the edges and the gap between the nanophosphors were clearly distinguished in the CL image (Fig. 1(c)), showing that the spatial-resolution of CL imaging was enough higher than that of UCL image. We believe that upconversion phosphors of the type described here will allow the realization of new CLEM imaging techniques covering the nanometer to millimeter scale, i.e., the molecular to in vivo scale.jmicro;63/suppl_1/i29/DFU073F1F1DFU073F1Fig. 1.(a) SEM and correlative (b) UCL (intensity of 980 nm NIR CW laser 8 mW) and (c) CL images of Y2O3:Tm,Yb nanophosphors in same region (accelerating voltage 3 kV, exposure time 100 ms/pixel).

Abstract
BACKGROUND AND PURPOSE Prasugrel is a third-generation thienopyridine prodrug and ticagrelor is a non-competitive P2Y12 receptor antagonist. In their phase 3 studies, both agents reduced rates of ischemic events relative to treatment with clopidogrel. EXPERIMENTAL APPROACH The pharmacodynamic profile of anti-platelet effects of prasugrel was compared with that of ticagrelor in rats. KEY RESULTS The active metabolite of prasugrel was less potent than ticagrelor and its active metabolite on platelet aggregation in vitro. In contrast, prasugrel was a more potent antiplatelet agent than ticagrelor on ex vivo platelet aggregation: their ED50 values at peak for ADP 20 μmol·L(-1) were 1.9 and 8.0 mg·kg(-1) , respectively. Prasugrel's inhibition of platelet aggregation was maintained for up to 24 h after administration, but ticagrelor's duration of action was substantially shorter. Prasugrel and ticagrelor significantly inhibited thrombus formation with ED50 values of 1.8 and 7.7 mg·kg(-1) , respectively. Both agents also prolonged bleeding times (ED200 values of 3.0 and 13 mg·kg(-1) respectively) suggesting that at equivalent levels of inhibition of platelet aggregation, the agents would show comparable antithrombotic activity with similar bleeding risk. Platelet transfusion significantly increased blood platelet numbers similarly in prasugrel- and ticagrelor-treated rats. In the prasugrel-treated group, platelet transfusion caused significant shortening of bleeding time, while in the ticagrelor-treated group, platelet transfusion showed no influence on bleeding time under the experimental conditions employed. CONCLUSIONS AND IMPLICATIONS Prasugrel and ticagrelor showed several differences in their pharmacological profiles and these disparities may reflect their differing reversibility and/or pharmacokinetic profiles.

Abstract
Macrophages (MΦ) are functionally classified into two types, anti-inflammatory M2 and pro-inflammatory M1. Importantly, we recently revealed that soluble HIV-1 proteins, particularly the pathogenetic protein Nef, preferentially activate M2-MΦ and drive them towards an M1-like MΦ, which might explain the sustained immune activation seen in HIV-1-infected patients. Here, we show that the preferential effect of Nef on M2-MΦ is mediated by TAK1 (TGF-β-activated kinase 1) and macropinocytosis. As with MAP kinases and NF-κB pathway, Nef markedly activated TAK1 in M-CSF-derived M2-MΦ but not in GM-CSF-derived M1-MΦ. Two Nef mutants, which were unable to activate MAP kinases and NF-κB pathway, failed to activate TAK1. Indeed, the TAK1 inhibitor 5Z-7-oxozeaenol as well as the ectopic expression of a dominant-negative mutant of TAK1 or TRAF2, an upstream molecule of TAK1, inhibited Nef-induced signaling activation and M1-like phenotypic differentiation of M2-MΦ. Meanwhile, the preferential effect of Nef on M2-MΦ correlated with the fact the Nef entered M2-MΦ more efficiently than M1-MΦ. Importantly, the macropinosome formation inhibitor EIPA completely blocked the internalization of Nef into M2-MΦ. Because the macropinocytosis activity of M2-MΦ was higher than that of M1-MΦ, our findings indicate that Nef enters M2-MΦ efficiently by exploiting their higher macropinocytosis activity and drives them towards M1-like MΦ by activating TAK1.

Abstract
Detection of tumor markers is important for cancer diagnosis. Field-effect transistors (FETs) are a promising method for the label-free detection of trace amounts of biomolecules. However, detection of electrically charged proteins using antibody-immobilized FETs is limited by ionic screening by the large probe molecules adsorbed to the transistor gate surface, reducing sensor responsiveness. Here, we investigated the effect of probe molecule size on the detection of a tumor marker, α-fetoprotein (AFP) using a FET biosensor. We demonstrated that the small receptor antigen binding fragment (Fab), immobilized on a sensing surface as small as 2–3 nm, offers a higher degree of sensitivity and a wider concentration range (100 pg/mL–1 μg/mL) for the FET detection of AFP in buffer solution, compared to the whole antibody. Therefore, the use of a small Fab probe molecule instead of a whole antibody is shown to be effective for improving the sensitivity of AFP detection in FET biosensors. Furthermore, we also demonstrated that a Fab-immobilized FET subjected to a blocking treatment, to avoid non-specific interactions, could sensitively and selectively detect AFP in human serum.

BACKGROUND The role of microchimerism found in the peripheral blood of renal transplant recipients remains a matter of debate. We assessed the frequency of microchimerism after kidney transplantation and examined its influence on clinical courses over a 12-month follow-up period. PATIENTS AND METHODS Ten single-kidney recipients underwent microchimerism detection at 2 days, 2 weeks, and 1, 3, 6, and 12 months after transplantation, with mismatch human leukocyte antigen (HLA)-A, -B, and -C used as markers. RESULTS Microchimerism was detected in 8 (80%) patients at 2 days after kidney transplantation. In 3 of those, microchimerism became negative within 3 months after transplantation, whereas it remained present for up to 12 months in 3 patients (33 %). There was 1 acute rejection episode in a patient in whom microchimerism became negative within 3 months. Protocol renal graft biopsy specimens obtained 3 months after transplantation revealed no acute cellular-mediated rejection (ACMR) or acute antibody-mediated rejection (AAMR) in the 5 patients positive for microchimerism at 3 months. CONCLUSIONS Microchimerism was frequently detected after kidney transplantation. Microchimerism that remained for more than 3 months post-transplantation might be correlated with a lower incidence of rejection, thus its monitoring may help identify recipients with a low rejection risk.

Abstract
OBJECTIVES The American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) remission criteria for rheumatoid arthritis (RA) are more stringent than index-based criteria, making it more difficult to achieve a patient's global assessment (PGA) than an evaluator's global assessment (EGA). We investigated the reason for the discrepancy between the PGA and the EGA in a Japanese clinical cohort. METHOD We assessed clinical and laboratory variables in our clinical cohort. The frequency of remission achievement according to the ACR/EULAR remission criteria and predictors of the discrepancy between the PGA and EGA were analysed. RESULTS Of 370 patients with RA, 89 fulfilled PGA criteria and 167 patients fulfilled EGA criteria. The PGA was highly correlated with the visual analogue scale (VAS) pain score and non-inflammatory variables including Steinbrocker class and the Health Assessment Questionnaire Disability Index (HAQ-DI). Conversely, inflammatory variables, including swollen joint count (SJC), tender joint count (TJC), and C-reactive protein (CRP) levels, were significantly associated with the EGA. The main predictors of the discrepancy between the PGA and the EGA were patient's VAS pain score, SJC, and functional disability. CONCLUSIONS Increased pain and functional disability led to a discrepancy towards a worse PGA than EGA, whereas increased SJC led to an accordance towards a worse EGA.

Abstract
MS/MS and imaging mass spectrometry analysis (IMS) were used to estimate mouse fatty liver. Triacylglycerol (TG) structure and distribution were measured using MS/MS and IMS. The most intense mass spectrum ion was indicated by IMS at m/z 881.7 (52:2). MS/MS showed a structural change between liver TG and dietary TG. MALDI-SpiralTOF with IMS could be a powerful tool for clinical screening of fatty liver.
Matrix-assisted laser desorption/ionisation spiral orbit-type time-of-flight mass spectrometry (MALDI-SpiralTOF) can analyse lipid profiles and characterise lipid structure. Imaging mass spectrometry (IMS) also provides distribution maps of selected m/z values. Here, we investigated triacylglycerol (TG) structure and distribution using these technologies to estimate mouse fatty liver. The distribution and intensity of the most intense mass spectrum ion was indicated by IMS at m/z 881.7 (52:2). Analysis using MS/MS showed a structural change between liver TG and dietary TG. These findings suggest that MALDI-SpiralTOF is a powerful tool for clinical screening and estimating fatty liver.

Abstract
BACKGROUND We evaluated the efficacy and safety of superselective embolization with assistance of colonoscopy for acute colonic hemorrhage. METHODS Of 92 cases of acute colonic hemorrhage requiring colonoscopic intervention, 11 (12 %) could not be successfully treated. Of these, 10 patients (9 men, mean age 65.5 years, range 39-75 years) underwent superselective embolization. Hemorrhage was caused by diverticular disease (n = 8), polypectomy (n = 1), and vascular malformation (n = 1). In all 10 cases, the radiopaque clips were placed at the bleeding point via colonoscopy. Microcatheters were used in all procedures, and embolization was performed at the level of the vasa recta leading to or near the clips with Gelfoam particles, microcoils, or both. RESULTS Immediate hemostasis was achieved in all patients. In 6 of 10 patients (60 %), selective angiograms showed no active extravasation at the time of the procedure and the embolization was performed using clips as a landmark. In the remaining four patients, selective angiograms showed active extravasation from the vasa recta leading to the clips. The mean number of embolized vessels with no active extravasation and with active extravasation was 1.83 (range 1-3) and 1.25 (range 1-2), respectively. The mean duration of clinical follow-up was 11.6 months (range 1-29 months). One patient (10 %) bled from a different site than the treated site a month after embolization, but the bleeding ceased after endoscopic intervention. All the patients (100 %) were evaluated for objective evidence of ischemia by colonoscopy. Four of the 10 patients (40 %) were found endoscopically to have small areas of ischemia involving only the mucosa, but they remained asymptomatic. There was no bowel infarction or stricture. CONCLUSIONS Colonoscopy-assisted superselective embolization may be a safe and useful procedure for acute colonic hemorrhage without active extravasation on angiogram.

Abstract
The electric capacitance and conductance of a model membrane composed of a hydrophobic filter paper and a synthetic lipid analogue, i.e., dioleylphosphate, immersed in an electrolyte solution were observed with various frequencies ranging from 20 to 3×10(6) Hz. With successive increase of salt concentration in the external solution, the capacitance and conductance of the membrane increased discontinuously at a certain critical value of the external salt concentration. This variation of the capacitance and conductance of the membrane with the salt concentration was found to be reversible, and the critical value of salt concentration was independent of the adsorbed quantity of the lipid, and of the pore size of the filter paper as far as the adsorbed quantity of the dioleylphosphate was large.A theoretical analysis based on the membrane model for the filter paper-phospholipid system proposed in Part I of this series revealed that the dioleylphosphate impregnated in the filter paper changed its conformation from oil droplets or globular micelles to a number of bilayer membranes when the salt concentration reached the critical value for a given pair of electrolyte species and the membrane. The conformational change of the lipid analogue in the filter paper is discussed in connection with the ability of formation and stability of a black bilayer membrane of the dioleylphosphate.

Abstract
AIM Main bile duct necrosis develops after transcatheter arterial chemoembolization (TACE) through the caudate artery (A1) and medial subsegmental artery (A4) of the hepatic artery in the treatment of hepatocellular carcinoma. The aim of this study was to evaluate the bile duct branch (BD branch) from A1 and A4. METHODS We evaluated the origin and vascular territory of the BD branch in 11 patients who underwent selective A1 and/or A4 arteriography using arteriograms, cone-beam computed tomography (CBCT) and CT obtained 1 week after TACE. Follow-up CT and/or magnetic resonance imaging were also evaluated. RESULTS The BD branch arose from the first branch (n = 4), the second branch (n = 1), and both the first and second branches (n = 1) of A1, and from the first branch of A4 (n = 5). It supplied the bilateral hepatic ducts and common hepatic duct (CHD) (n = 4), the right hepatic duct (RHD) and CHD (n = 2), RHD, CHD and common bile duct (n = 1), the left hepatic duct (LHD) and CHD (n = 2), and LHD alone (n = 2). Anastomosis between A1 or A4 and other branches was demonstrated in seven patients. Bile duct stricture developed in all nine patients 2-8 months after TACE of the BD branch and percutaneous transhepatic bile duct drainage and metallic stent placement was required in one because of jaundice. CONCLUSION The BD branch arises from the proximal portion of A1 and A4 and mainly supplies the hepatic ducts and CHD.

Abstract
Protooncogene T-cell leukemia 1 (TCL1), which is implicated in human T-cell prolymphocytic leukemia (T-PLL), interacts with Akt and enhances its kinase activity, functioning as an Akt kinase co-activator. Two major isoforms of TCL1 Protooncogenes (TCL1 and TCL1b) are present adjacent to each other on human chromosome 14q.32. In human T-PLL, both TCL1 and TCL1b are activated by chromosomal translocation. Moreover, TCL1b-transgenic mice have never been created. Therefore, it remains unclear whether TCL1b itself, independent of TCL1, exhibits oncogenicity. In co-immunoprecipitation assays, both ectopic and endogenous TCL1b interacted with Akt. In in vitro Akt kinase assays, TCL1b enhanced Akt kinase activity in dose- and time-dependent manners. Bioinformatics approaches utilizing multiregression analysis, cluster analysis, KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway mapping, Venn diagrams and Gene Ontology (GO) demonstrated that TCL1b showed highly homologous gene-induction signatures similar to Myr-Akt or TCL1. TCL1b exhibited oncogenicity in in vitro colony-transformation assay. Further, two independent lines of β-actin promoter-driven TCL1b-transgenic mice developed angiosarcoma on the intestinal tract. Angiosarcoma is a rare form of cancer in humans with poor prognosis. Using immunohistochemistry, 11 out of 13 human angiosarcoma samples were positively stained with both anti-TCL1b and anti-phospho-Akt antibodies. Consistently, in various cancer tissues, 69 out of 146 samples were positively stained with anti-TCL1b, out of which 46 were positively stained with anti-phospho-Akt antibodies. Moreover, TCL1b structure-based inhibitor 'TCL1b-Akt-in' inhibited Akt kinase activity in in vitro kinase assays and PDGF (platelet-derived growth factor)-induced Akt kinase activities-in turn, 'TCL1b-Akt-in' inhibited cellular proliferation of sarcoma. The current study disclosed TCL1b bears oncogenicity and hence serves as a novel therapeutic target for human neoplastic diseases.

Abstract
OBJECTIVE To examine the relationship between primary progressive aphasia (PPA) and neurodegenerative dementia. METHODS Subjects were selected from 1723 consecutive patients who had undergone a medical examination at the Kumamoto University Hospital Dementia Clinic, Japan, from April 2007 to October 2012. First, patients with semantic dementia (SD) and patients with progressive non-fluent aphasia were diagnosed by clinical diagnostic criteria for frontotemporal lobar degeneration. Next, in the same cohort, patients with PPA were diagnosed according to the recent international consensus criteria. The relationship and clinical symptoms including language and psychiatric symptoms in each patient group were then compared. RESULTS In all, 12 of 27 SD patients fulfilled both SD and semantic variant PPA criteria (SD+PPA+ group), whereas the other 15 who met the SD criteria could not be included in the semantic variant PPA group due to prominent behavioural disturbances (SD+PPA- group). No significant differences in clinical characteristics and language functions were found between these 2 groups. Neuropsychiatric symptoms were more severe in the SD+PPA- group. CONCLUSION The results suggest the possibility that SD and semantic variant PPA may be identical, regardless of different severities of behavioural disturbance. When considering the language disorder of neurodegenerative dementia, it may be more important to diagnose the subtype of language disorder the patient has than to emphasise isolated language deficits.

Abstract
PURPOSE This study was designed to compare technical success and local recurrence rates of transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) with/without monitoring of embolized areas using cone-beam computed tomography (CBCT). METHODS A total of 207 HCCs ≤6 cm were treated with superselective TACE using digital subtraction angiography (DSA) alone (DSA group, 98 tumors of 70 patients) or plus CBCT monitoring (CBCT group, 109 tumors of 79 patients). Technical success of TACE was classified into three grades according to 1-week CT; the tumor was embolized with a safety margin (5-mm wide for tumors <25 mm, and 10-mm wide for tumors 25≥ and ≤60 mm; grade A), without a margin in parts (grade B), or the entire tumor was not embolized (grade C). Technical success and local recurrence rates in the DSA and CBCT groups were compared. Local recurrence rates of grade A and B tumors were also compared. RESULTS The grade A/B/C tumors in the DSA and CBCT groups were 64 (65.3%)/25 (25.5%)/9 (9.2%) and 95 (87.2%)/11 (10.1%)/3 (2.8%), respectively. Local recurrence developed in 46/158 (29.1%) grade A tumors and 24/36 (66.7%) grade B. There were significant differences in technical success between the DSA and CBCT groups (p < 0.001) and local recurrence rates between grade A and B tumors (p < 0.001). The 1-, 2-, and 3-year local recurrence rates in the DSA and CBCT groups were 33.3 and 22.3%, 41.3 and 26.8%, and 48 and 30.6%, respectively (p = 0.0217). CONCLUSION Intraprocedural CBCT monitoring of embolized areas reduces the local tumor recurrence.

Abstract
A new MALDI-TOF/TOF system with monoisotopic precursor selection was applied to the analysis of triacylglycerols in an olive oil sample. Monoisotopic precursor selection made it possible to obtain product-ion mass spectra without interference from species that differed by a single double bond. Complete structure determination of all triacylglycerols, including structural isomers, was made possible by interpreting the charge-remote fragmentation resulting from high-energy collision-induced dissociation (CID) of the sodiated triacylglycerols.

Abstract
PURPOSE To evaluate the performance of transcatheter arterial chemoembolization guidance software that uses cone-beam computed tomography (CT) technology in identifying small hepatocellular carcinoma (HCC) tumors and feeding branches. MATERIALS AND METHODS Cone-beam CT and manual feeder vessel detection (MFD) software were used in chemoembolization of 68 HCCs 30 mm or smaller (mean ± standard deviation, 15.3 mm ± 5.2). Detectability of tumors and tumor-feeding sub-subsegmental arteries was compared versus that of nonselective digital subtraction angiography (DSA). Technical success of chemoembolization was divided into three grades according to 1-week CT findings: entire tumor embolized with at least a 5-mm-wide margin (ie, complete), tumor embolized without a margin in parts (ie, adequate), or entire tumor not embolized (ie, incomplete). All cone-beam CT data were also reanalyzed with automatic feeder vessel detection (AFD) software that was developed later. RESULTS Cone-beam CT could depict all tumors, including eight that were first discovered during chemoembolization. Sixty-one tumors (89.7%) were detected on CT during arterial portography and during hepatic arteriography, and seven (10.3%) were detected with one or the other. Nonselective DSA depicted 49 tumors (72.1%). Among 100 tumor-feeding vessels, 81 were identified with MFD and 38 with nonselective DSA. Detectability of tumors with CT and tumor-feeding branches with MFD was significantly better than with nonselective DSA (both P<.001). Fifty-nine tumors (86.8%) were completely embolized and nine (13.2%) were adequately embolized. AFD identified 96 feeder vessels; 88 (88%) represented true-positive findings. CONCLUSIONS Transcatheter arterial chemoembolization guidance software with cone-beam CT technology has a sufficient performance level to detect small HCCs and their feeding branches.

Abstract
PURPOSE To evaluate the performance of transcatheter arterial chemoembolization guidance software that uses cone-beam computed tomography (CT) technology in identifying small hepatocellular carcinoma (HCC) tumors and feeding branches. MATERIALS AND METHODS Cone-beam CT and manual feeder vessel detection (MFD) software were used in chemoembolization of 68 HCCs 30 mm or smaller (mean ± standard deviation, 15.3 mm ± 5.2). Detectability of tumors and tumor-feeding sub-subsegmental arteries was compared versus that of nonselective digital subtraction angiography (DSA). Technical success of chemoembolization was divided into three grades according to 1-week CT findings: entire tumor embolized with at least a 5-mm-wide margin (ie, complete), tumor embolized without a margin in parts (ie, adequate), or entire tumor not embolized (ie, incomplete). All cone-beam CT data were also reanalyzed with automatic feeder vessel detection (AFD) software that was developed later. RESULTS Cone-beam CT could depict all tumors, including eight that were first discovered during chemoembolization. Sixty-one tumors (89.7%) were detected on CT during arterial portography and during hepatic arteriography, and seven (10.3%) were detected with one or the other. Nonselective DSA depicted 49 tumors (72.1%). Among 100 tumor-feeding vessels, 81 were identified with MFD and 38 with nonselective DSA. Detectability of tumors with CT and tumor-feeding branches with MFD was significantly better than with nonselective DSA (both P<.001). Fifty-nine tumors (86.8%) were completely embolized and nine (13.2%) were adequately embolized. AFD identified 96 feeder vessels; 88 (88%) represented true-positive findings. CONCLUSIONS Transcatheter arterial chemoembolization guidance software with cone-beam CT technology has a sufficient performance level to detect small HCCs and their feeding branches.

Abstract
PURPOSE To evaluate the performance of transcatheter arterial chemoembolization guidance software that uses cone-beam computed tomography (CT) technology in identifying small hepatocellular carcinoma (HCC) tumors and feeding branches. MATERIALS AND METHODS Cone-beam CT and manual feeder vessel detection (MFD) software were used in chemoembolization of 68 HCCs 30 mm or smaller (mean ± standard deviation, 15.3 mm ± 5.2). Detectability of tumors and tumor-feeding sub-subsegmental arteries was compared versus that of nonselective digital subtraction angiography (DSA). Technical success of chemoembolization was divided into three grades according to 1-week CT findings: entire tumor embolized with at least a 5-mm-wide margin (ie, complete), tumor embolized without a margin in parts (ie, adequate), or entire tumor not embolized (ie, incomplete). All cone-beam CT data were also reanalyzed with automatic feeder vessel detection (AFD) software that was developed later. RESULTS Cone-beam CT could depict all tumors, including eight that were first discovered during chemoembolization. Sixty-one tumors (89.7%) were detected on CT during arterial portography and during hepatic arteriography, and seven (10.3%) were detected with one or the other. Nonselective DSA depicted 49 tumors (72.1%). Among 100 tumor-feeding vessels, 81 were identified with MFD and 38 with nonselective DSA. Detectability of tumors with CT and tumor-feeding branches with MFD was significantly better than with nonselective DSA (both P<.001). Fifty-nine tumors (86.8%) were completely embolized and nine (13.2%) were adequately embolized. AFD identified 96 feeder vessels; 88 (88%) represented true-positive findings. CONCLUSIONS Transcatheter arterial chemoembolization guidance software with cone-beam CT technology has a sufficient performance level to detect small HCCs and their feeding branches.
