Model finds polyp surveillance effective for cancer prevention

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.

Coronary CTA study aims for lowest dose

A study from Switzerland concludes that low-dose prospectively gated coronary CT angiography (CTA) is both feasible and promising, but not without wrinkles. Relying on prospectively triggered gating and some of the lowest radiation doses yet achieved for prospectively gated coronary CTA, the team reported that 95% of all coronary segments achieved diagnostic image quality, but image quality was very dependent on heart rate.

Sublingual nitroglycerin improves coronary CTA

Nitroglycerin significantly improves the results of coronary CT angiography (CTA) by dilating the coronary arteries before scanning, researchers in Belgium have reported. Their study found that vessel lumen diameters and average volumes were larger when nitroglycerin spray was administered sublingually before scanning. Their study appears in the January issue of the American Journal of Roentgenology.

VC program takes off in nonacademic setting

Radiologists in Belgium have built a popular virtual colonoscopy practice they credit with increasing awareness of colorectal cancer screening in their community and reducing unnecessary optical colonoscopies. The screening model offers a glimpse of what U.S.-based community screening practice might look like with a bit of reimbursement.

Five-modality Munich trial finds high sensitivity for OC, VC

A virtual colonoscopy screening trial performed entirely on 64-detector-row CT found clinically significant polyps nearly as accurately as optical colonoscopy, researchers report. The Munich Colorectal Cancer Prevention Trial incorporated five separate colorectal cancer screening modalities in the same screening cohort. The researchers presented their results at the recent 2007 International Symposium on Virtual Colonoscopy in Boston.

VC in elderly patients yields extracolonic advantage

Virtual colonoscopy is a valuable screening tool in symptomatic individuals age 70 and older, yielding diagnostic benefits far beyond the scope of barium enema exams, which remain common in the U.K. due to staffing and equipment issues, researchers report in this month's American Journal of Roentgenology.

Advanced liver imaging shapes surgical strategies

The days of planning liver interventions on the strength of a few CT or MR reconstructions may be numbered. Researchers from Germany and beyond are honing a set of advanced planning tools that not only provide high-resolution color-coded 3D visualization of the liver parenchyma and vasculature, but offer quantitative views of the intrahepatic vessel branching system and the risks of cutting at a given point in the organ.

Giant virtual reality chamber boosts 3D echo accuracy

Have you ever diagnosed a three-foot-tall 3D heart? Talk about cardiomegaly. Researchers from the Netherlands who survived the experience found they could diagnose valve defects that went unnoticed in a standard 2D exam. At the 2007 Computer Assisted Radiology and Surgery (CARS) meeting in Berlin, Anton Koning, Ph.D., from Erasmus University Medical Center in Rotterdam discussed how 3D visualizes complex pathology of the heart and how image display can be improved with different kinds of VR (virtual reality) systems.

Two-segment CTA reconstruction aids images, not accuracy

For patients with faster heart rates, the use of two-segment reconstruction improves image quality at 64-slice coronary CT angiography (CTA), according to a study from Germany. Among all patients, however, accuracy was not improved using two-segment when compared to single-segment reconstruction.
