I-ELCAP data suggest need to work up secondary lung lesions
Lung cancer screening data from the I-ELCAP trial suggest that patients with secondary tumors might benefit from more aggressive management, and that metastases, at least in the predominant non-small cell lung cancers, may be less common than previously thought. The data also suggest that revisions in the current staging criteria may help save lives.

CT differentiates mesenteric ischemia from transmural necrosis
Researchers in Korea have found CT useful for differentiating transmural ischemic necrosis from nontransmural ischemia, potentially sparing some patients the need for surgical intervention.

Familial links may improve patient selection for lung cancer screening
The past decade has seen substantial growth in lung cancer screening, which has benefited from government funding and improvements in MDCT technology and CAD software. But studies suggest that improvements in mortality may come at a high cost. New research, however, offers hope for lowering screening costs through better selection of the screening population based on genetics and familial linkage.

Automated CO2 insufflation maintains lead
Automated CO2 insufflation improves colonic distension for virtual colonoscopy compared to manual CO2 insufflation, particularly in the left colon, researchers from the U.K. reported in the January American Journal of Roentgenology.

MDCT equals MRI for RV function assessment
Right ventricular (RV) parameters and function are known to have major prognostic import in patients with heart disease and chronic pulmonary embolism, but RV assessment can be challenging with CT, compared to the MRI gold standard. But researchers from Germany have found that 16-slice MDCT was statistically equivalent to cine MRI for estimating RV volumes, ejection fraction, and other important parameters.

Twenty-nine states pay for some diagnostic VC
Slow and steady is winning the race for virtual colonoscopy. As of this month, 29 states have finalized local coverage decisions at the Medicare Carrier Advisory Committee level authorizing VC reimbursement after incomplete colonoscopy. And during the first quarter of 2006, local coverage decisions are pending approval in six more states.

VC CAD found equivalent to colonoscopy in screening population
The National Institutes of Health (NIH) scored a CAD coup this month with a study concluding that its VC computer-aided detection (CAD) system yielded sensitivities that were statistically equivalent to that of optical colonoscopy for significant polyps in a large screening population.

Breast CT developers aim to 'revolutionize' mammography
Researchers in California are hoping to revolutionize mammography quite literally -- with the aid of a prototype conebeam CT scanner that acquires images in a single revolution around the breast. In a preliminary study, its sensitivity for the detection of breast cancer was comparable to that of two-view mammography.
