Unusual multiple large abscesses of the liver: interest of the radiological features and the real-time PCR to distinguish between bacterial and amebic etiologies.

We report a rare case of amebiasis generating 19 large liver abscesses. Such a quantity of abscesses is rare, especially when occurring in a young casual traveler without any immunodeficiency disorders. A possible co-infection was excluded.

Accuracy of a new method for semi-quantitative assessment of right ventricular ejection fraction by cardiovascular magnetic resonance: right ventricular fractional diameter changes.

Objective: Longitudinal shortening is traditionally considered the predominant part of global right ventricular (RV) systolic function. Less attention has been paid to transverse contraction. The aim of this study was to evaluate RV transverse motion by cardiovascular magnetic resonance (CMR) in a large cohort of patients and to assess its relationship with RV ejection fraction (RVEF).

Safety of meglumine gadoterate (Gd-DOTA)-enhanced MRI compared to unenhanced MRI in patients with chronic kidney disease (RESCUE study).

Objective: To prospectively compare the renal safety of meglumine gadoterate (Gd-DOTA)-enhanced magnetic resonance imaging (MRI) to a control group (unenhanced MRI) in high-risk patients.

Methods: Patients with chronic kidney disease (CKD) scheduled for MRI procedures were screened. The primary endpoint was the percentage of patients with an elevation of serum creatinine levels, measured 72 ± 24 h after the MRI procedure, by at least 25 % or 44.

[Left and right ventricular volumetry and ejection fraction with MRI: segmentation criteria and interobserver reproducibility].

Purpose: To propose and validate anatomical criteria for the manual segmentation of right and left ventricles on cardiac MRI, to evaluate the interobserver reproducibility and tho evaluate the ease of implementation.

Materials And Methods: Criteria for the segmentation and the choice of the basal slices were defined based on a review of the literature and cardiac anatomy. Cardiac volumetric measurements obtained from 20 consecutive patients using these criteria were compared to measurements obtained in reference to the orthogonal planes, and to those obtained with the classical criteria described in the literature.

[Current indications for cardiac CT].

There is a need to define the current indications for coronary CT angiography (CCTA) even as technology continuously evolves. CCTA using 64 MDCT units has shown to be highly accurate for diagnosis of stenoses >or=50% on selected populations. It is currently used for its negative predictive value (96-98%).
