Will Improved Vascular Mapping Achieved with Gadobenate Dimeglumine Aid in Interpretation of Breast MR Images?
The findings of Sardanelli et al show not only that gadobenate dimeglumine can be used to obtain vascular maps that are superior to those obtained with gadopentetate dimeglumine but also that a difference in vascularity between the two breasts is an indirect sign of malignancy.

American College of Radiology Clinical Statement on Noninvasive Cardiac Imaging
This clinical statement of the American College of Radiology (ACR) discusses various technical and patient safety issues related to cardiac CT and MR imaging, and it suggests appropriate qualifications for radiologists until such time as ACR practice guidelines for the performance of cardiac CT and cardiac MR imaging are written and approved through the usual ACR process.

Feasibility of Integrating High-Spatial-Resolution 3D Breath-hold Coronary MR Angiography with Myocardial Perfusion and Viability Examinations
It seems feasible to complete a cardiac MR imaging examination that facilitates myocardial perfusion, myocardial viability, and proximal and middle coronary artery vessel assessments within 30–45 minutes.

Quantitative Assessment of Left Ventricular Function: Steady-State Free Precession MR Imaging with or without Sensitivity Encoding
The results of this study suggest that sensitivity encoding–assisted cine acquisitions with steady-state free precession (SSFP) can help to reduce examination time while producing left ventricular functional assessment data comparable to those achieved with conventional cine SSFP acquisitions.

New Suction Guide Needle Designed to Reduce the Incidence of Biopsy-related Pneumothorax: Experimental Evaluation in Canine Model
The results of the present experiment are promising because we significantly reduced the incidence of intraprocedural pneumothoraces by using the suction guide needle.

Contrast Medium–induced Nephrotoxicity: Which Pathway?
The current article by Heinrich et al in Radiology provides a renewed focus on the direct tubular cell toxicity pathway of contrast medium–induced acute renal failure and, in my opinion, a promising pathway to solve a growing clinical crisis.
