'Uniquely higher' relaxivity rates give gadobenate an edge
By Shalmali Pal
Not all gadolinium-based agents are created equal, and those agents with a higher relaxivity point offer a number of advantages in clinical MRI, according to a study in the American Journal of Neuroradiology. In this in vitro study, the investigators from the University of Pittsburgh in Pennsylvania demonstrated differences among various gadolinium-based contrast agents.

Model finds polyp surveillance effective for cancer prevention
By Eric Barnes
The risk of developing colorectal cancer from polyps found at virtual colonoscopy but left unresected is not precisely known, and the practice of polyp surveillance is still controversial. But a new study concludes that the low likelihood of advanced neoplasia combined with the high cost of colonoscopy argue against the immediate removal of small lesions.

By Eric Barnes
Radiologists routinely administer both an oral barium suspension and IV contrast for evaluating suspected appendicitis, diverticulitis, and small-bowel obstruction (SBO). Would studies work as well without oral contrast? And what about oral iodine? Can it replace barium in abdominal applications other than virtual colonoscopy? Two research groups recently explored these issues.
