CT use cuts negative appendectomy rates
By Eric Barnes
CT is highly sensitive and specific for identifying acute appendicitis in both men and women, concludes a June 21 study in the Annals of Internal Medicine. In nearly 3,000 patients with suspected acute appendicitis, CT of the abdomen and pelvis appeared to reduce negative appendectomy and perforation rates.

Chest-wall toxicity risk predictable by SBRT dose
By Cynthia E. Keen
Stereotactic body radiation therapy (SBRT) is producing impressive rates of local control for malignant lung and liver lesions. An article published in the July issue of the International Journal of Radiation Oncology, Biology, Physics identifies dose-volume parameters that predict the risk of chest-wall toxicities for these patients.

Colon cancer rare 5 years after negative VC screening
By Eric Barnes
Patients without significant polyps at virtual colonoscopy screening can rest easy for at least five years, according to a study from the University of Wisconsin. The results, which showed one colon cancer case among more than 1,000 patients, suggest that recommended screening intervals are appropriate.

Ascending colon rotation can mask colonic polyps
By Eric Barnes
Polyps in the ascending colon can mimic mobile contents such as fecal matter when patients turn from prone to supine position at virtual colonoscopy, potentially skewing interpretation, a new study indicates. Simple awareness of the phenomenon can go a long way toward helping radiologists avoid misinterpretation of virtual colonoscopy results.

Fast 320-row CT produces lower dose in pancreas
By Eric Barnes
The image quality of contrast-enhanced CT scans of the pancreas was pretty much equivalent between fast 320-detector-row contrast-enhanced scans of the pancreas and 64-detector-row scans, according to a new study in Radiology. But there were some differences, notably far lower radiation doses with the 320-row scans.
