Abstract
In France, three varieties of therapeutic plasma are being processed, distributed and delivered, currently; however, many more varieties are in use worldwide, which go by the property of labile blood component or plasma derived medicines. For one type of component (one given name), several devices and bags and so on are used to concur to its process, which makes that one type of therapeutic plasma may significantly differ from one production setting to one other. This may affect (more or less) the component properties as well as the possibly reported adverse events. This review aims thus, firstly at stressing on the difficulty in comparing data obtained in different contexts, and secondly at making the point on future directions to process therapeutic plasma.

Abstract
In the past few years, pathogen reduction technologies for labile blood products have been part of the enhancement of global transfusion safety regarding residual risks of transmitting infectious pathogens. Having carried out a feasibility study for the implementation of pathogen inactivation of platelet concentrates by means of the amotosalen/HCl/UVA (Intercept™) technology, and participated to a reinforced haemovigilance study, we took the opportunity to analyze the organization consequences for platelet concentrates inventory and distribution. This impact study first indicated that those novel needs forced the blood donation service, as well as the labile blood product preparation laboratory, to review and improve practices; secondly, it showed that the routine implementation has little (no major) consequence in the overall organization, independently of the economic consequences (not covered here).

Abstract
The noninvasive evaluation of liver fibrosis is a major clinical goal in liver diseases. Our aim was to identify MRI parameters to quantify liver fibrosis in vivo in an animal model of liver fibrosis with slight inflammation. We evaluated serum hyaluronate, liver hydroxyproline, area of liver fibrosis (image analysis), and 1.5-T MRI in 10 sham rats and 24 bile duct ligated rats with different stages of liver fibrosis. Liver signal intensity (SI)/muscle SI ratio and liver relaxation times (rT) were measured on T1 and T2 weighted sequences at different echo (TE) or recovery (RT) times of MRI. Among the 66 MRI parameters tested, the highest correlation with the area of fibrosis was observed for rT2 (r=0.78, P < 0.01). The area of liver fibrosis was independently predicted by five MRI variables (adjusted R (2)=0.78, with R (2)=0.64 for rT2 and rT1). Diagnostic accuracy for liver fibrosis was 100% using two variables: liver/muscle SI ratio on T2 at 30-ms TE and liver/muscle SI ratio on T1 at 50-ms RT. We conclude that in this animal model, fibrosis could be diagnosed with an accuracy of 100% using two MRI parameters. The quantification of liver fibrosis was very accurate either with only one MRI parameter (r=0.78 for rT2) or with five parameters (r=0.90) in this cholestatic model.

Abstract
PURPOSE Diagnosis and quantification of hepatic fibrosis are especially important in patients with chronic liver disease. Liver biopsy remains the gold standard for diagnosis of cirrhosis but has several limitations. The purpose of this study was to determine the usefulness of diffusion-weighted MR imaging, for the diagnosis of cirrhosis and quantification of hepatic fibrosis, and to define the best sequence parameters for this evaluation. METHODS AND MATERIALS Diffusion-weighted imaging using a 1.5 T MR unit was performed in 14 healthy volunteers and 13 cirrhotic patients. Sets of 8 images with different b values (200, 400, 600, and 800 sec/mm2) and different TR (3500 and 5000 ms) were acquired with breath-holding. Apparent diffusion coefficients (ADCs) were calculated. Correlation between Child-Pugh scores, serum hyaluronate concentrations and ADCs were performed. RESULTS ADCs were significantly lower in cirrhotic patients (2,055 10-3) compared to controls (2,915 10-3) (p<0.05) when the b value was 200 s/mm2 and the TR was 5000 ms. Significant correlations were observed between Child-Pugh scores and ADCs (p<0.05), and between serum hyaluronate concentrations and ADCs (p<0.05), when the b value was 400 sec/mm2 and the TR was 5000 ms. CONCLUSION Our preliminary study showed that the measurement of ADCs has good potential for diagnosis and quantification of hepatic fibrosis, especially when using b values of 200 sec/mm2 and 400 sec/mm2.

Abstract
PURPOSE To prospectively determine whether a relationship exists between magnetic resonance (MR) imaging abnormalities of the right ventricle (RV) and intracardiac electrophysiologic (EP) test results in patients with myotonic dystrophy. MATERIALS AND METHODS Conventional T1-weighted single-shot black-blood fast spin-echo and gradient-echo MR imaging of the heart was prospectively performed in 32 patients with myotonic dystrophy who required EP testing. Patients were divided into two groups according to EP test results: (a) inducible (n = 15), indicating inducible ventricular tachyarrhythmias, and (b) noninducible (n = 17). Morphologic and functional MR data were analyzed by two independent investigators. Nonparametric statistical methods and kappa statistics were used. RESULTS No morphologic or functional abnormalities of the RV wall were observed in noninducible patients. Increased signal intensity of the RV wall, indicative of fatty replacement, was identified in 13 inducible patients. Myocardial thinning of the RV was observed in six inducible patients. An overlap of morphologically abnormal areas and areas of hypo- or dyskinesis were present in 11 inducible patients. RV outflow tract diameter was larger and RV ejection fraction was smaller in inducible patients than in noninducible patients, although differences were not significant. Interobserver agreement for MR findings was good (increased signal intensity: kappa = 0.87, P >.30 [pairwise Wilcoxon signed rank test]; myocardial thinning: kappa = 0.87, P >.30; hypo- or dyskinesis: kappa = 1.00, P >.99). There was a strong relationship between MR abnormalities and inducibility during EP testing (increased signal intensity, P <.001; myocardial thinning, P <.01; hypo- or dyskinesis, P <.01). CONCLUSION The relationship between MR morphologic and functional RV abnormalities and EP testing suggests potential for the use of MR imaging as a noninvasive method to estimate the individual risk of arrhythmia in patients with myotonic dystrophy.

Abstract
PURPOSE To compare the reproducibility of left ventricular (LV) mass measurements using a black-blood half-Fourier single-shot fast spin-echo (SSFSE) and a segmented gradient echo magnetic resonance (MR) pulse sequence. MATERIAL AND METHODS Breath-hold SSFSE and segmented gradient echo cardiac MR examinations were performed twice in 32 patients and manual detection of the LV endocardium and epicardium was applied by two blinded reviewers. The SSFSE pulse sequence allowed whole-heart coverage in a single breath hold, while multiple breath holds were required using the segmented gradient echo sequence. Spatial presaturation slabs were used with the SSFSE pulse sequence to reduce the field of view (FOV) and thereby achieve higher spatial resolution. RESULTS Intraclass correlation coefficients were higher with the SSFSE pulse sequence than with the segmented gradient echo pulse sequence: intraobserver reproducibility reached 0.999 vs. 0.991; interobserver reproducibility: 0.997 vs. 0.981; and interstudy reproducibility: 0.998 vs. 0.936. These higher levels of reproducibility were confirmed on Bland and Altman plots. CONCLUSION LV mass measurements can be assessed more reproducibly with the single breath-hold SSFSE technique than with the standard multiple breath-hold segmented gradient echo method.

Abstract
At liver magnetic resonance (MR) imaging in 38 patients, a breath-hold T2-weighted fast spin-echo (SE) pulse sequence optimized with fast recovery was compared with a conventional respiratory-triggered fast SE sequence and a breath-hold single-shot fast SE sequence. Mean signal-to-noise ratios for liver and contrast-to-noise ratios for hepatic lesions were higher with the breath-hold fast-recovery fast SE sequence than with the respiratory-triggered fast SE sequence (P <.05). Breath-hold fast-recovery images displayed better lesion clarity than did single-shot fast SE images (P <.05) and fewer image artifacts than did respiratory-triggered fast SE images (P <.05). The ability to determine lesion size and the overall image quality was best with the breath-hold fast-recovery sequence (P <.05). These results may justify use of the breath-hold fast-recovery fast SE pulse sequence for first-line T2-weighted MR imaging of the liver.

Abstract
A conventional T1-weighted spin-echo (SE) magnetic resonance (MR) imaging sequence was compared with breath-hold and non-breath-hold half- Fourier single-shot fast SE MR sequences with black-blood preparation and high spatial resolution for imaging of various cardiac diseases. The optimized single-shot fast SE sequence provided better or equal image quality in less time. Breath-hold and non-breath-hold single-shot fast SE sequences may replace the conventional T1-weighted SE sequence for first-line cardiac MR imaging.

Abstract
In 24 patients presenting with 55 renal lesions (mean size, 20.8 mm), single-breath-hold (SBH) fast spin-echo (FSE) techniques allowing T1 and T2 images to be produced within 20 and 23 sec, respectively, were compared with routine non-breath-hold (NBH) spin-echo (SE) T1 and NBH-FSE T2 sequences. Contrast-to-noise ratios (CNRs) measured from SBH-FSE T1 images were an average of 97% higher than their NBH counterparts (P = .0001) and allowed an improved lesion conspicuity in 80% of the cases (P = 0.0001). For T2 imaging, SBH-FSE and NBH-FSE sequences were not statistically different with respect to lesion conspicuity (P = .55) and CNR values (P = .19). This was observed despite a 35% average decrease in CNR of SBH-FSE compared to NBH-FSE images. By reducing respiratory motion artifacts while preserving SE-like image contrast, SBH-FSE techniques have the potential to replace routine NBH sequences for an optimal diagnosis of renal masses.
