Cardiac MR measures predict pulmonary hypertension

Cardiac MRI is opening a new diagnostic window on pulmonary hypertension (PH), according to a pair of studies from Mount Sinai Medical Center in New York City. The first study focused on detecting PH by measuring the ventricular septal-to-free-wall curvature ratio. The second used phase-contrast MRI to determine that average blood velocity is strongly correlated to pulmonary pressure and resistance.

New developments improve VC -- and colonoscopy

Virtual colonoscopy is improving in important ways -- as it must to keep up with optical colonoscopy. But considering that innovations in conventional colonoscopy also impact the value of VC, radiologists would be wise to stay up-to-date with those improvements as well, according to a recent presentation at the European Congress of Radiology (ECR) in Vienna.

Dual-phase PET/CT useful in lung nodule assessment

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.

Chest CT shows whirlpool patients in hot water

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.

Lower tube current aids circle of Willis imaging

Reducing the tube dose improved the image quality substantially in a CT study of the circle of Willis, according to investigators from the University of Utrecht in the Netherlands. The group sought to assess the effects of lower tube voltage and various mAs settings in patients undergoing CT angiography (CTA) of the head.

Radiographers equivalent to radiologists in VC study

Finding polyps may be a tough job, but radiologists aren't any better at it than radiographers, according to the results of a new virtual colonoscopy study by researchers from the Netherlands. The findings suggest that dedicated radiographers trained in reading VC exams can be as accurate as radiologists in evaluating the exams.

VC CAD ramps up detection of medium-sized polyps

VIENNA - U.S. National Institutes of Health (NIH) researchers, who spent years developing an advanced VC computer-aided-detection (CAD) scheme, recently revamped the polyp-detection algorithm to significantly improve its performance. They presented their research on the updated system today at the European Congress of Radiology (ECR).
