MR experts take issue with FDA gadolinium warning
By Shalmali Pal
In May 2007, the U.S. Food and Drug Administration (FDA) recommend that a "black box" warning label be places on all gadolinium-based contrast agents. Now a group of MR safety experts have deemed the FDA's suggestion as "imprudent." They argue that the risk of a patient with renal disease developing nephrogenic systemic fibrosis (NSF) does not currently appear to be the same among the various gadolinium-based MR contrast agents.

Computer-assisted MR guidance improves prostate biopsy
By Eric Barnes
An automated prostate biopsy system based on real-time guidance with high-field MRI earned high scores for accuracy and image quality, according to German researchers. They found that using a transgluteal needle approach to the prostate with the patient prone was accurate and safe when used in combination with the pneumatically driven needle positioning system.

MR adds value to urodynamics for imaging stress urinary incontinence
By Shalmali Pal
The spectrum of abnormalities detected at MRI in women with stress urinary incontinence can be classified into two categories: findings related to urethral sphincter deficiency (ISD) and/or urethral hypermobility (UH). Researchers from Baltimore-based Johns Hopkins Medical Institutions assessed if MR findings could predict whether a patient had ISD or UH, and if those results could be correlated with urodynamics.

Renal artery size varies widely; stent filters don't fit
By Eric Barnes
A review of abdominal multidetector-row CT (MDCT) angiograms found significant size differences between left and right renal arteries, between men and women, and between patients. These differences have serious implications for the increasingly common use of distal filtering devices to prevent distal atheroembolization after percutaneous transluminal renal angioplasty (PTRA). The devices are designed for carotid and coronary arteries, and more often than not don't fit, according to the study authors.

Obesity and prostate cancer: Should imaging have a role in screening?
By Kate Madden Yee
Prostate cancer remains a significant health concern in the U.S., where nearly 235,000 men were diagnosed with the disease last year. Preliminary research in obese men strongly suggests that these patients are susceptible to more aggressive cancers and higher mortality rates, and traditional prostate cancer screening exams are not always accurate in this population. Experts weigh in on whether screening obese patients with imaging would be a better bet.

Homogeneity at CT distinguishes renal cysts from cancer
By Eric Barnes
Renal cysts are common and benign; renal carcinoma is not. And distinguishing some high-attenuating cysts from cancer on a typical unenhanced CT scan can be difficult, if not impossible. But researchers from Yale University think they've succeeded in sorting them out fairly accurately, if only to inform the decision for the next exam.
