Eric Barnes[email protected]Clinical NewsBlood infection risk extremely low with VCThe risk of bloodstream infections such as bacteremia leading to endocarditis is extremely low in virtual colonoscopy -- in fact, infection rates are probably even lower than in conventional colonoscopy, say researchers from Ireland, the U.K., and the U.S.March 30, 2010Clinical NewsHeart rate key to image quality in low-dose coronary CTAHeart rate control is an important factor for success in prospectively gated coronary CT angiography (CTA). But once patients are beta-blocked, the success rate is high and the doses are uniformly low, according to a new study by Swiss researchers.March 28, 2010Clinical NewsDiverticular disease favors prone over supine VC imagesDiverticular disease, an unfortunate result of low-fiber Western diets that increases in incidence with age to burden most of the elderly population, has a friend in virtual colonoscopy. That's because VC generally provides an easier colon exam for both patient and provider than conventional colonoscopy.March 25, 2010ConferenceOrgan-based tube-current modulation cuts breast doseVIENNA - Radiation doses to the breast can be cut by nearly 40% using a new organ-based dose modulation technique in combination with a noise-optimized image reconstruction method. The two techniques must be used together if the resulting images are to remain readable, researchers reported.March 7, 2010ConferenceOne-day bowel prep eases VC for patients, providersVIENNA - A one-day bowel prep and virtual colonoscopy exam regimen offers sufficiently good image quality, making life easier for both patients and providers compared to a multiday regimen, according to a study presented Sunday at the European Congress of Radiology.March 6, 2010ConferenceCT doses, widely variable in Europe, are reduced by staff effortsVIENNA - Although dose variations remain wide on the continent, there are opportunities for substantial improvement with dose-reduction training and programs, according to two European studies of clinical CT doses presented back-to-back Saturday at the European Congress of Radiology.March 5, 2010ConferenceCoronary CTA predicts long-term outcomesVIENNA - A decade's worth of coronary CT angiography (CTA) studies is starting to reveal the modality's long-term predictive powers, if a study from one of Poland's largest heart centers is any indication.March 5, 2010ConferenceHigh pitch equals low dose in coronary CT angiographyVIENNA - High-pitch dual-source CT exams can evaluate the coronary arteries using about a third of the dose of even prospectively triggered exams, according to a study presented in Thursday's cardiac sessions of the European Congress of Radiology.March 3, 2010Clinical News320-row CT minimizes dose in pediatric abdominal studiesIt's no secret that CT radiation dose levels in children -- especially in the emergency department, where patients are fidgety and physicians need fast answers -- are too high. One solution, investigated by researchers from Toronto and Berlin, is wide-area-detector scans with 320-detector-row CT.March 2, 2010Clinical NewsCT blood-flow measurement gauges stenosis severity64-detector-row CT has sufficient temporal resolution to measure blood flow through the heart, offering the promise of a new functional test based on CT alone, according to a proof-of-concept study by German researchers.February 25, 2010Previous PagePage 47 of 59Next PageTop StoriesWomens ImagingHybrid AI reading shows success in breast cancer screeningA Dutch team found that a hybrid reading strategy for screening mammography reduced radiologist workload by 38% without changing recall or cancer detection rates.Medical, Legal, and PracticeCooking robot gets rave reviews in TübingenMRIUltrasound plus MRI helps diagnose pain from rotator cuff tendinopathyMedical, Legal, and PracticePressure grows for more rigorous financial disclosureMRIMRI, CT findings correlate for assessing epicardial fat volume
