These days CT is taking on a bigger role in presurgical planning, with increasing use of 3D measurements. And according to Korean researchers, the measurements based on 3D reconstructions are accurate and reproducible.May 30, 2006MRIHigh osmolarity agent beats gadolinium in cardiac MRA compact but concentrated dose of high-osmolarity contrast agent produced a better MR contrast profile than gadolinium in patients with chronic thromboembolic pulmonary hypertension, a U.K. team has reported.May 29, 2006Abdominal ImagingX-ray alien head vanishes from duck stomachNews of an apparent extraterrestrial being that was lodged in a duck's gizzard is grabbing headlines from San Francisco to cyberspace. Workers at the International Bird Rescue Research Center in Cordelia, CA, were stunned when they examined a plain radiograph of a sick mallard, according to workers at the center.May 25, 2006Cardiac ImagingAuntMinnie.com Cardiac Imaging InsiderMay 23, 2006CTStudies suggest 10-year colonoscopy intervals to age 80Two population-based studies in the latest Journal of the American Medical Association address critical topics in colorectal cancer screening with optical colonoscopy. The results suggest that once-a-decade screening is sufficient for average-risk patients, but that the potential of screening to extend lives diminishes by age 80.May 22, 2006CTConcentrated iodine permits lower volumes in cardiac CTACardiac CT can be performed successfully with lower contrast volumes and flow rates when contrast agents are more concentrated, according to a new study. Researchers in Germany reported that 16-slice cardiac CT angiography (CTA) produced equivalent opacification compared to the use of a less-concentrated agent and higher volumes.May 21, 2006CTPart I: Radiologists prepare for growing CT role in virtual autopsyImaging has a big future in virtual autopsy, and CT in particular seems headed for a major role. Noninvasive virtual exams can often do what traditional autopsy cannot, notably in identifying the dead and pinpointing the causes of death. For all but a few applications, investigators are finding CT to be the fastest and most accurate modality available to carry out this work.May 21, 2006CTAuntMinnie.com CT Radiology InsiderMay 16, 2006CTPart II: Automated CT lung nodule assessment advancesPart II of our series on automated CT nodule assessment explores the how and why of lung nodule assessment in a few computer-aided detection (CAD) systems. The results of some recent studies suggest that current CAD algorithms may need more emphasis on the small, irregularly shaped nodules that constitute many primary lung cancers.May 15, 2006Previous PagePage 191 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
