Lack of virtual colonoscopy coverage a barrier to screening
By Eric Barnes
A survey of primary care patients who were offered but did not undergo colon cancer screening found that more than four-fifths would be willing to undergo virtual colonoscopy -- but not if they had to pay the entire cost out of pocket.

Constipated kids don't need abdominal x-rays
By Cynthia E. Keen
The practice of ordering an abdominal x-ray exam for constipated children to assess the presence of retained feces or to confirm a diagnosis made during a physical exam should be stopped, as the procedure is of limited value, according to an analysis published online in Pediatric Radiology.

Contrast US processing tool shows malignant liver lesions
By Eric Barnes
Swiss researchers have developed a real-time parametric imaging technique for distinguishing benign from malignant liver lesions easily and noninvasively using contrast-enhanced ultrasound. In its first clinical run, the method delivered high sensitivity and specificity in a patient cohort.

VC not cost-effective -- unless screening rates rise
By Eric Barnes
In a new model analysis published Tuesday in the Journal of the National Cancer Institute, virtual colonoscopy was generally less cost-effective than several other colon cancer screening tests, including conventional colonoscopy. However, VC would become the most cost-effective test if it were to increase colon cancer screening rates.

Pancreatic CT pitfalls can be avoided
By Eric Barnes
Evaluating pancreatic CT images to determine resectability is one of the more difficult jobs in radiology, perhaps more so because the stakes are so high. But a lot of mistakes can be avoided with 3D imaging and careful attention to a few details.

Requiring prone and supine CAD marks boosts VC results
By Eric Barnes
Radiologists detect more polyps when computer-aided-detection (CAD) software is required to mark lesions on both prone and supine views at virtual colonoscopy before findings can be deemed positive, according to a new study in Academic Radiology.
