New method corrects for hyperattenuation surrounding tagged VC data

Fluid and fecal tagging is a proven method of distinguishing polyps from residual materials in virtual colonoscopy. But tagged, highly attenuated regions tend to "bleed" into adjacent structures on CT images. Researchers from Boston are addressing the problem with a method to electronically subtract the spillover attenuation without otherwise affecting the images.

Elderly need less contrast for pancreatobiliary imaging

Older patients need less contrast than younger adults for pancreatobiliary imaging, researchers from Japan report. The results of their study, published in the August American Journal of Roentgenology, showed that a 12% contrast dose reduction by body weight produced the optimal contrast profile in multidetector-row CT's triphasic imaging protocols.

2D, 3D primary VC have their own advantages

There's no right or wrong choice for primary reading when it comes to 2D or 3D virtual colonoscopy. But whichever method you choose, you'll need the other to confirm the findings. Dr. Judy Yee from the University of California, San Francisco, recently discussed both primary reading methods, and some of the latest study results on 2D versus 3D.

Window levels matter when viewing submerged polyps in VC

Tagging regimens are increasingly popular among virtual colonoscopy providers, who want to optimize lesion conspicuity and thereby avoid undetected lesions. But finding submerged polyps in 2D means paying careful attention to the attenuation of tagged fluid and window settings, according to new research from the U.K.

Extracolonic findings double VC costs, but might be worth paying

Following up extracolonic findings in virtual colonoscopy can easily double the cost of exams in symptomatic patients, but even the occasional detection of significant pathology may make it cost-effective, researchers from the U.K. report.

2D primary reading plus CAD has an edge in VC study

In comparing 2D primary reading to 3D for virtual colonoscopy interpretation, 3D yielded lower sensitivity and more false positives, and took significantly longer to complete. But a computer-aided reading scheme applied to both methods was helpful, according to a study in the June issue of Radiology.

Data, not fear, should drive CT decisions in pregnancy

Deciding whether to scan a pregnant patient with CT can be one of the toughest decisions in radiology. At the recent International Symposium on Multidetector-Row CT in San Francisco, two presenters addressed some of the risks and fears of CT in pregnancy.

Upper GI series catches gastric bypass complications, guides additional treatment

By Shalmali Pal

An upper gastrointestinal series after bariatric surgery can alert surgeons to the need for postsurgical modifications, according to a presentation last week at the American Society for Bariatric Surgery (ASBS) meeting in San Francisco. Cleveland-based investigators reviewed close to 1,000 patient records for their study.
