Abstract
The adrenal gland is a common site of a large spectrum of abnormalities like primary tumors, hemorrhage, metastases, and enlargement of the gland from external hormonal stimulation. Most of these lesions represent nonfunctioning adrenal adenomas and thus warrant a conservative management. Multi-detector computed tomography (CT) and magnetic resonance (MR) imaging are still considered highly specific and complementary techniques for the detection and characterization of adrenal abnormalities. Radiologist can establish a definitive diagnosis for most adrenal masses (i.e., carcinoma, hemorrhage) based on imaging alone. Imaging therefore can differentiate malignant lesions from those benign and avoid unnecessary aggressive management of benign lesions. The article gives an overview of the adrenal lesions and their imaging characteristics seen on CT and MR imaging.

Abstract
BACKGROUND The aim of this paper was to compare the use of two different commercially available vascular closure devices (VCD), Angioseal VIP® (St. Jude Medical, St. Paul, MN, USA) and StarClose SE (Abbott Laboratories, Abbott Park, IL, USA). METHODS From January 2010 to January 2012, 347 patient underwent retrograde femoral arterial puncture for different interventional procedures (angioplasty, stenting, embolization for bleeding, fibrinolysis for ischemia and chemoembolization). Hemostasis was achieved by deployment of an Angioseal VIP® (N.=184) or StarClose SE® (N.=163). In 94 cases, the retrograde femoral access was bilateral and managed with two StarClose SE devices (N.=53) or an Angioseal VIP® plus a StarClose SE® (N.=41). RESULTS Technical success was obtained in 95.1% (330/347) of patients. Overall time to hemostasis (TTH) and time to ambulation (TTA) were 5,5±1,5 min (range 3-8 min) and 6±2.5 hr (range 2-9 hours) respectively. No statistical significative difference (P>0.05) were appreciable between to groups for both TTH and TTA: Angioseal VIP® TTH was 5.3±1.4 min and StarClose SE® TTH was 5.6±1.6 min; Angioseal VIP® TTA was 5.9±1.8 hr and StarClose SE® TTA was 6.1±1.9 hr. VAS scores result underline a mild difference between two devices. Angioseal VIP® patients experience a mild to moderate pain within the first 3 minutes from the deployment. Whereas StarClose SE® patients still experience pain at 5 minutes from deployment. The device failure rate was 4.9% (17 cases) and included 13 minor complications and 4 major complications. Minor complications (3.75%) occurred during the initial phase and consisted in recurrent wound bleeding (N.=5 StarClose SE®; N.=4 Angioseal VIP®) treated with manual compression, and hematoma (N.=2 StarClose SE®; N.=2 Angioseal VIP®) that solved spontaneously. The 4 major complications (1,15%) were: 1 Angioseal-related common femoral artery (CFA) obstruction treated with surgical bypass from the CFA to the superficial femoral artery; 1 Angioseal-related CFA dissection solved with surgery; 1 Angioseal-related embolization of the deep femoral artery partially treated with localized fibrinolysis; 1 StarClose-related pseudoaneurysm treated with manual compression. CONCLUSIONS Both Angioseal VIP® and StarClose SE® systems can be considered safe and effective in providing hemostasis following a variety of interventional vascular procedures.

Abstract
AIM To evaluate the efficacy of dynamic contrast-enhanced magnetic resonance (DCE-MR) in the response to anti-angiogenic-targeted agents in patients with metastatic renal cell cancer (mRCC). PATIENTS AND METHODS Twenty-eight consecutive patients with sub-diaphragmatic metastases from mRCC were included in the protocol after signed informed consent. Baseline characteristics were collected and patients were first evaluated with a baseline computed tomography (CT) and DCE-MR, subsequently with a new DCE-MRI after 28 days of therapy and followed-up with CT until progression. Treatments were administered at standard doses. The changes of peak enhancement (ΔPE) and of the sum of longest tumor diameters (ΔLTD) were related to progression-free survival (PFS) and overall survival (OS). RESULTS The median PFS was 11.4 months [95% Confidence Interval (CI): 7.9-14.7 months) and the parametric two-tailed Pearson's test showed a positive correlation between the median ΔPE and the median PFS (rp=0.809; p=0.015); no significant correlation was found between the median ΔLTD and the median PFS (rp=-0.446; p=0.27). The median OS was 23.3 months (95% CI: 13.6-33.0 months) and no significant correlation was found with the median ΔPE (rp=0.218; p=0.60) or with the median ΔLTD (rp=0.012; p=0.98). CONCLUSION The ΔPE but not the ΔLTD was found to be significantly related to PFS; these preliminary results suggest extending the number of patients and investigating the possible relationship with other tumor characteristics and MRI parameters.

Abstract
Atherosclerosis involving the carotid arteries has a high prevalence in the population worldwide. This condition is significant because accidents of the carotid artery plaque are associated with the development of cerebrovascular events. For this reason, carotid atherosclerotic disease needs to be diagnosed and those determinants that are associated to an increased risk of stroke need to be identified. The degree of stenosis typically has been considered the parameter of choice to determine the therapeutical approach, but several recently published investigations have demonstrated that the degree of luminal stenosis is only an indirect indicator of the atherosclerotic process and that direct assessment of the plaque structure and composition may be key to predict the development of future cerebrovascular ischemic events. The concept of "vulnerable plaque" was born, referring to those plaque's parameters that concur to the instability of the plaque making it more prone to the rupture and distal embolization. The purpose of this review is to describe the imaging characteristics of "vulnerable carotid plaques."

Abstract
OBJECTIVE To determine whether CT-perfusion (CT-p) can be used to evaluate the effects of chemotherapy and anti-angiogenic treatment in patients with non-small-cell lung carcinoma (NSCLC) and whether CT-p and standard therapeutic response assessment (RECIST) data obtained before and after therapy correlate. METHODS 55 patients with unresectable NSCLC underwent CT-p before the beginning of therapy and 50 of them repeated CT-p 90 days after it. Therapeutic protocol included platinum-based doublets plus bevacizumab for non-squamous carcinoma and platinum-based doublets for squamous carcinoma. RECIST measurements and calculations of blood flow (BF), blood volume (BV), time to peak (TTP) and permeability surface (PS) were performed, and baseline and post-treatment measurements were tested for statistically significant differences. Baseline and follow-up perfusion parameters were also compared based on histopathological subclassification (2004 World Health Organization Classification of Tumours) and therapy response assessed by RECIST. RESULTS Tumour histology was consistent with large cell carcinoma in 14/50 (28%) cases, adenocarcinoma in 22/50 (44%) cases and squamous cell carcinoma in the remaining 14/50 (28%) cases. BF and PS differences for all tumours between baseline and post-therapy measurements were significant (p=0.001); no significant changes were found for BV (p=0.3) and TTP (p=0.1). The highest increase of BV was demonstrated in adenocarcinoma (5.2±34.1%), whereas the highest increase of TTP was shown in large cell carcinoma (6.9±22.4%), and the highest decrease of PS was shown in squamous cell carcinoma (-21.5±18.5%). A significant difference between the three histological subtypes was demonstrated only for BV (p<0.007). On the basis of RECIST criteria, 8 (16%) patients were classified as partial response (PR), 2 (4%) as progressive disease (PD) and the remaining 40 (80%) as stable disease (SD). Among PR, a decrease of both BF (18±9.6%) and BV (12.6±9.2%) were observed; TTP increased in 3 (37.5%) cases, and PS decreased in 6 (75%) cases. SD patients showed an increase of BF, BV, TTP and PS in 6 (15%), 21 (52.5%), 23 (57.5%) and 2 (5%) cases, respectively. PD patients demonstrated an increase of BF (26±0.2%), BV (2.7±0.1%) and TTP (3.1±0.8%) while only PS decreased (23±0.2%). CONCLUSION CT-p can adequately evaluate therapy-induced alterations in NSCLC, and perfusion parameters correlate with therapy response assessment performed with RECIST criteria. ADVANCES IN KNOWLEDGE Evaluating perfusional parameters, CT-p can demonstrate therapy-induced changes in patients with different types of lung cancer and identify response to treatment with excellent agreement to RECIST measurements.

Abstract
We report a case of an isolated hepatic neoplasia which originated in a site of the liver previously affected by radiation induced liver disease (RILD) in a patient resected for gastric cancer and referred to us for high serum alpha-fetoprotein (AFP) levels. This case challenged us in distiguishing, even histologically, between primary liver cancer and AFP producing gastric cancer metastasis. Only a panel of immunohistochemical markers allowed the definitive diagnosis of liver metastasis of endodermal stem cell-derived and AFP producing gastric cancer. We discuss the criteria for a differential diagnosis, as well as the possible link between RILD and emergence of liver neoplasia.

Abstract
PURPOSE The main hallmark of Takotsubo cardiomyopathy (TT-CMP) is transient ischaemia, with completely reversible regional contractile dysfunction, which involves the mid-apical segments and shows no angiographic signs of coronary artery disease (CAD). The acute and reversible myocardial injury suggests that tissue oedema may be an important marker of disease. MATERIALS AND METHODS Seventeen patients with a clinical and angiographic diagnosis of TT-CMP underwent cardiovascular magnetic resonance (CMR) imaging in the acute phase and at follow-up after 4 months. A standard acquisition protocol including turbo spin echo (TSE) T2-weighted short-tau inversion-recovery (T2 STIR), steady-state free-precession cine (SSFP cine) and lateenhancement (LE) imaging after gadolinium benzyloxypropionic tetraacetic acid (Gd-BOPTA) administration was performed. All images were analysed, and data on oedema and LE were correlated with regional dysfunction and histological findings from endomyocardial biopsy (EMB) where available. RESULTS In all patients, T2 STIR images showed a diffuse homogeneous hyperintensity that extended to all mid-apical segments and perfectly matched the area of regional dysfunction, reflecting tissue oedema. In the five patients who underwent EMB, histology confirmed the massive interstitial oedema associated with typical contraction-band necrosis. No cases of LE were observed. At follow-up, complete regression of oedema was observed in all cases, with significant recovery of regional and global left ventricular (LV) function (ejection fraction from 48.7% to 59.8%). CONCLUSIONS Myocardial oedema on CMR is a characteristic feature of acute TT-CMP, which reflects acute inflammation and acute myocardial injury. It could therefore be used as a specific marker of disease severity.

Abstract
BACKGROUND The right ventricle (RV) has been defined as the "forgotten chamber", as its role in cardiac physiopathology has long been underestimated. Nevertheless, the RV is involved in a wide range of pathological conditions and its altered function may significantly affect the patient's clinical status. METHODS A selection of the most common cardiovascular magnetic resonance (CMR) features in a spectrum of pathological conditions is illustrated. Although its complex morphology, thin myocardium and trabeculated apex, RV can be accurately imaged by CMR, revealing its involvement in ischaemic and non-ischaemic heart disease. CMR has emerged as the pre-eminent modality in monitoring ventricular performance in congenital heart disease, pulmonary hypertension and cardiomyopathies. Arrhythmogenic right ventricular cardiomyopathy is a difficult diagnosis and the recently revised task force criteria confirmed a crucial role of CMR to increase diagnostic accuracy, by combining detection of RV dilation, regional wall motion and structural abnormalities. Moreover, a multiparametric approach of CMR is often necessary for delineation and characterisation of cardiac masses. CONCLUSION CMR, combining assessment of morphology, structure and function, has definitively emerged as the reference technique to evaluate a large variety of RV diseases. TEACHING POINTS • CMR offers unique advantages for imaging of many RV congenital, ischaemic and non-ischaemic diseases. • Because of high reproducibility, CMR has a crucial role in decision-making for chronic RV pathology. • The use of CMR increases detection of RV disease as infarction or arrhythmogenic cardiomyopathy.

Abstract
PURPOSE To determine the preliminary feasibility, safety, and clinical efficacy of magnetic resonance (MR)-guided focused ultrasound for the treatment of painful osteoid osteoma. MATERIALS AND METHODS This prospective institutional review board-approved study involved six consecutive patients (five males and one female; mean age, 21 years) with a diagnosis of osteoid osteoma based on clinical and imaging findings. All patients underwent MR-guided focused ultrasound ablation after providing informed consent. Lesions located in the vertebral body were excluded. The number of sonications and the energy deposition were recorded. Treatment success was determined at 1, 3, and 6 months after treatment. A visual analog scale (VAS) score for pain was used to assess changes in symptoms. MR imaging features of osteoid osteoma (edema, hyperemia, and nidus vascularization) were considered at baseline and at imaging follow-up. RESULTS Treatment was performed with a mean of 4 sonications ± 1.8 (standard deviation), with a mean energy deposition of 866 J ± 211. No treatment- or anesthesia-related complications occurred. The pre- and posttreatment mean VAS scores significantly differed (7.9 ± 1.4 and 0.0 ± 0.0, respectively). At imaging, the edema and hyperemia associated with osteoid osteoma gradually disappeared in all lesions. However, nidus vascularization still persisted after treatment in four of six patients. CONCLUSION This limited series demonstrated that MR-guided focused ultrasound treatment of osteoid osteoma can be performed safely with a high rate of success and without apparent treatment-related morbidity.

Abstract
Quantitative ultrasound (US) elastography (Q-USE), able to evaluate tissue stiffness has been indicated as a new diagnostic tool to differentiate benign from malignant thyroid lesions. Aim of this prospective study, conducted at the Department of Surgical Sciences, of the “Sapienza” University of Rome, was to evaluate the diagnostic accuracy of Q-USE, compared with US parameters, in thyroid nodules with indeterminate cytology (Thy3).The case study included 140 nodules from 140 consecutive patients. Patient’s thyroid nodules were evaluated by Q-USE, measuring the strain ratio (SR) of stiffness between nodular and surrounding normal thyroid tissue, and conventional US parameters prior fine-needle aspiration cytology. Those with Thy3 diagnosis were included in the study. Forty of the nodules analyzed harbored a malignant lesion. Q-USE demonstrated that malignant nodules have a significant higher stiffness with respect to benign one and an optimun SR cut-off value of 2.05 was individuated following ROC analysis. Univariate analysis showed that hypoechogenicity, irregular margins and SR >2.05 associated with malignancy, with an accuracy of 67.2%, 81,0% and 89.8%, respectively. Data were unaffected by nodule size or thyroiditis. These findings were confirmed in multivariate analysis demonstrating a significant association of the SR and the irregular margins with thyroid nodule’s malignancy. In conclusion, we demonstrated the diagnostic utility of Q-USE in the differential diagnosis of thyroid nodules with indeterminate cytology that, if confirmed, could be of major clinical utility in patients’ presurgical selection.

Abstract
OBJECTIVES To prospectively compare the diagnostic performance of ultrasound (US), multidetector computed tomography (MDCT) and contrast-enhanced magnetic resonance imaging (MRI) in cirrhotic patients who were candidates for liver transplantation. METHODS One hundred and forty consecutive patients with 163 hepatocellular carcinoma (HCC) nodules underwent US, MRI and MDCT. Diagnosis of HCC was based on pathological findings or substantial growth at 12-month follow-up. Four different image datasets were evaluated: US, MDCT, MRI unenhanced and dynamic phases, MRI unenhanced dynamic and hepatobiliary phase. Diagnostic accuracy, sensitivity, specificity, PPV and NPV, with corresponding 95 % confidence intervals, were determined. Statistical analysis was performed for all lesions and for three lesion subgroups (<1 cm, 1-2 cm, >2 cm). RESULTS Significantly higher diagnostic accuracy, sensitivity and NPV was achieved on dynamic + hepatobiliary phase MRI compared with US, MDCT and dynamic phase MRI alone. The specificity and PPV of US was significantly lower than that of MDCT, dynamic phase MRI and dynamic + hepatobiliary phase MRI. Similar results were obtained for all sub-group analyses, with particular benefit for the diagnosis of smaller lesions between 1 and 2 cm. CONCLUSIONS Dynamic + hepatobiliary phase MRI improved detection and characterisation of HCC in cirrhotic patients. The greatest benefit is for diagnosing lesions between 1 and 2 cm.

Abstract
While reports of venous calcifications are scarce, vascular calcifications frequently occur in the arteries of uraemic patients. Venous calcification of an aged arterious-venous (a-v) fistula in a young patient with a long-standing history of hyperparathyroidism was detected on a forearm X-ray. Risk factors for vascular calcifications are still under debate, but calcium-phosphate product appears to be involved in its pathogenesis. We suggest that a-v fistula of patients with hyperparathyroidism history should be monitored as calcifications could be a risk factor for access thrombosis.

Abstract
Persistent sciatic artery is a very uncommon embryologic vascular variant, with a prevalence of 0.05% based on angiographic studies. Two different types of this anomaly can occur, complete or incomplete, on the basis of the relationship between sciatic artery and femoral artery. Although many of these patients are asymptomatic, it may represent a threat to the viability of the lower extremity because of atherosclerotic degeneration resulting in aneurysmal dilatation, occlusive thrombosis, or embolic phenomena with distal complication. We present a case of a 64-year-old man with combined, complete and incomplete, type of persistent sciatic artery causing ischemic ulcer of the first toe.

Abstract
The evaluation and management of prostate cancer (PCa) are based mainly on parameters such as the serum prostate-specific antigen level, clinical stage, and pathologic findings at biopsy or after surgery. The aim of this paper was to review the current roles of conventional imaging and multiparametric magnetic resonance imaging (mpMRI) techniques in the diagnosis of PCa. A non systematic literature search using the Medline and Cochrane Library databases was performed up to January 2012. Bibliographies of retrieved articles and review articles were also examined. Only those articles reporting complete data with clinical relevance for the present review (i.e., diagnosis, staging) were selected. The advent of a high performance (1.5T) and higher fields strength (3T), and thus, higher spatial resolution, increased the potentiality and the diffusion of MR examinations. Intense research has focused on the use of complementary techniques to improve the detection, characterization, and staging of PCa by MRI. This review article is divided into two major parts: the first one considers the technical aspects of mpMRI; the second part is intended to provide the impact of this technique on patients with PCa. Published data indicate an emerging role for MRI (particularly mpMRI combining T2 weighted imaging, diffusion weighted imaging, contrast enhanced MR, and spectroscopy) as the most sensitive and specific tool available for imaging PCa. MpMRI can provide metabolic information, characterize tissue and tumor vascularity, as well as tissue cellularity and correlate with tumor aggressiveness.
