Noncathartic bowel prep facilitates, complicates virtual colonoscopy
SAN FRANCISCO - Studies suggest that virtual colonoscopy without cathartic bowel preparation is feasible and sufficiently accurate. More patients might be willing to get screened. But if prepless VC makes patients' lives easier, it complicates matters for radiologists. Dr. Michael Zalis from Massachusetts General Hospital in Boston discussed several issues that impact the emergence of a kinder, gentler screening exam at the International Symposium on Multidetector-Row CT.

Inverse-geometry CT project promises higher image quality, fewer artifacts
SAN FRANCISCO - A new research project aims to take CT imaging to the next level with a design known as inverse-geometry CT (IGCT), which incorporates multiple detector arrays for wide field-of-view imaging. Researchers from Stanford University discussed the details of their project and the new technology at this week's International Symposium on Multidetector-Row CT.

Renal artery size varies widely; stent filters don't fit
A review of abdominal multidetector-row CT (MDCT) angiograms found significant size differences between left and right renal arteries, between men and women, and between patients. These differences have serious implications for the increasingly common use of distal filtering devices to prevent distal atheroembolization after percutaneous transluminal renal angioplasty (PTRA). The devices are designed for carotid and coronary arteries, and more often than not don't fit, according to the study authors.

Significant extracolonic cancer found in VC screening patients
Unsuspected extracolonic cancers are found in about one in 300 asymptomatic virtual colonoscopy (VC) screening subjects, according to a new study of more than 5,000 individuals who underwent colon cancer screening. The results add weight to the argument that following up the most serious extracolonic findings can potentially benefit outcomes.

Patients show slight preference for MR colonography over colonoscopy
Most patients who underwent MR colonography (MRC) and optical colonoscopy preferred MRI, according to a new study by researchers from Essen, Germany, and Atlanta, GA. When the patients were questioned about which colorectal screening test they'd rather have in the future, however, MR's advantage dwindled.

Marijuana increases lung cancer risk
Despite the biological plausibility of marijuana being carcinogenic, and suggestions that overall lung cancer risk may be associated with pot smoking, epidemiologic findings of marijuana use have been weaker and far less consistent than studies associating tobacco smoking with lung cancer. But a new study from New Zealand finds that pot smokers do indeed face higher lung cancer rates that increase for every year of smoking, and for patients who begin smoking younger.

VC measurements more accurate than optical colonoscopy
Virtual colonoscopy did a better job of measuring polyps than optical colonoscopy, and optimized 2D measurements were slightly more accurate than 3D, according to a just-published study from South Korea. The measurements affect not only thresholds for removal, but also polyp-matching algorithms in both modalities, explained the researchers from the Asan Medical Center and Seoul National University Hospital in Seoul.

256-slice CT brings new possibilities in head imaging
Researchers in Japan and the U.S. are producing promising new head CT images on a work-in-progress 256-slice scanner. A major advantage of so-called area detector scanning is the ability to acquire morphologic and functional images in a single scan, yielding a clutch of new diagnostic possibilities and time-saving exam protocols.

Study correlates CTA to angiography, myocardial perfusion SPECT
An ambitious effort to compare the results of coronary CT angiography (CTA), catheter angiography, and myocardial perfusion SPECT imaging yielded good overall agreement in patients with known or suspected heart disease. The researchers, from the Medical University of South Carolina in Charleston, believe CT could potentially replace the other modalities in patients with known or suspected coronary artery disease.

Big Japanese study finds benefit in CT lung screening
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.
