Big Japanese study finds benefit in CT lung screening
By Eric Barnes
SAN FRANCISCO - A lung cancer screening study of nearly 20,000 subjects in Japan found smaller tumors and improved survival rates with CT. Another study, from Oklahoma City, confirmed that CT-detected lung nodules that were stable over two years' time would remain benign.

Bill would boost funds for colorectal screening
By Eric Barnes
After years of congressional cost-cutting, colorectal cancer screening could be in line for a booster shot. A bill introduced in the U.S. Senate (S. 1164) would restore full Medicare reimbursement for approved colorectal cancer screening exams such as colonoscopy and flexible sigmoidoscopy.

Divergent research on CT lung screening sparks more debate, fewer answers
By Wayne Forrest
There is no doubt in the healthcare community that multislice CT finds more potentially cancerous lung nodules than chest x-ray. But CT's efficacy in reducing mortality among patients with suspicious lung nodules has become considerably less conclusive and more divergent with the release of two recent research reports.

CAD results vary by lung nodule location, morphology; another method measures solid component of GGOs
By Eric Barnes
In two recent studies that looked at automated computer-aided detection (CAD) software, researchers from the Netherlands examined the accuracy and reproducibility of automated nodule volume measurements in LungCare software. A third study by U.S. researchers sought to automatically measure the solid component of ground-glass nodules containing both solid and nonsolid components.

CT screening for lung cancer: Implications on social responsibility
Radiology is positioned to play a key role in the exciting endeavor of CT screening for lung cancer. Radiologists should be optimistic about the possible social benefits that this new technology promises, but should cautiously move forward and continually evaluate the associated risks, then properly relay these findings to patients so they can make educated decisions.

Dual-phase PET/CT useful in lung nodule assessment
By Eric Barnes
The use of dual-phase PET/CT can help distinguish benign from malignant lung nodules when F-18 FDG uptake is low, according to a new study from Korea. A group from the National University of Pusan sought to assess the utility of dual-phase PET/CT to differentiate benign from malignant lung disease with low F-18 FDG uptake.

US is best bet in male breast, but only if imaging is absolutely necessary
By Shalmali Pal
Male breast cancer is rare, but the incidence of the disease is rising due to shifts in diet and environment, among other things. Dr. Robin Wilson from the London-based Guy's Hospital discusses why he prefers sonography over mammography for examining the male breast, as well as what imaging experts should look for on these exams.

64-slice cardiac CT points to important incidental findings
By Edward Susman
NEW ORLEANS - Performing cardiac CT on a 64-slice scanner, even with a limited field-of-view, can often reveal significant findings outside the heart, which clinicians need to follow up, according to a presentation this week at the American College of Cardiology (ACC) meeting.

Chest CT shows whirlpool patients in hot water
By Eric Barnes
Northern Californians beware: a granulomatous disease known as hot tub lung may result from exposure to Mycobacterium avium complex (MAC) in your friendly neighborhood whirlpool bath. A new survey found characteristic CT patterns of nodules and ground-glass opacities in the lungs of MAC patients who had spent time in hot tubs.
