Eric Barnes[email protected]MRICardiac MR measures predict pulmonary hypertensionCardiac 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.April 8, 2007CTNew developments improve VC -- and colonoscopyVirtual 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.April 5, 2007CTDual-phase PET/CT useful in lung nodule assessmentThe 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.April 3, 2007CTAuntMinnie.com Virtual Colonoscopy InsiderApril 1, 2007CTChest CT shows whirlpool patients in hot waterNorthern 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.March 27, 2007CTLower tube current aids circle of Willis imagingReducing 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.March 21, 2007CTRadiographers equivalent to radiologists in VC studyFinding 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.March 18, 2007MRI1.5T, 3.0T MRI are equivalent for assessing myocardial infarctionIn a new study by researchers from the U.K., 1.5- and 3.0-tesla MRI showed strong agreement in both mass and transmural extent of myocardial hyperenhancement (HE) when using the same imaging sequence for patients with previous myocardial infarction.March 14, 2007CTPrepless VC a gentle alternative for elderlyVIENNA - Prepless virtual colonoscopy with oral contrast is a viable alternative to aggressive oral cleansing preparation and colonoscopy in frail, elderly patients, researchers from Ireland reported at the European Congress of Radiology (ECR).March 12, 2007CTVC CAD ramps up detection of medium-sized polypsVIENNA - 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).March 11, 2007Previous PagePage 178 of 258Next PageTop StoriesMolecular ImagingPET predicts faster cognitive decline in women than menWomen initially outperformed men at low brain tau levels, but the advantage diminished as tau levels increased over time.MRIUnclear explanations of contrast MRI exams heighten patient anxietyWomens ImagingMammography screening improves survival for late-stage cancersUltrasoundUltrasound MinnieCast, Episode 2: Body imaging with RUS-PATSponsor ContentHow Agentic AI Is Transforming Radiology Ops
