Eric Barnes[email protected]Molecular ImagingMDCT, SPECT, and echo agree on LV functionSure, multidetector-row CT can do arteries, but how about global and regional left ventricular (LV) function? It can indeed assess them accurately, researchers from the Netherlands reported in the European Journal of Nuclear Medicine and Molecular Imaging.August 6, 2006CTPart II: Virtual autopsy promises better data on U.S. military casualtiesOur final installment on the growing use of CT in autopsy discusses its use in the U.S. military, which since 2005 has performed whole-body multislice CT as part of a comprehensive forensic and pathological assessment of every soldier, sailor, airman, or Marine killed in a theater of war. An officer from the Armed Forces Institute of Pathology details the successes and the problems encountered in the high-volume scanning operation.August 2, 2006CTElderly need less contrast for pancreatobiliary imagingOlder patients need less contrast than younger adults for pancreatobiliary imaging, researchers from Japan report. The results of their study, published in the August American Journal of Roentgenology, showed that a 12% contrast dose reduction by body weight produced the optimal contrast profile in multidetector-row CT's triphasic imaging protocols.August 1, 2006CT2D, 3D primary VC have their own advantagesThere's no right or wrong choice for primary reading when it comes to 2D or 3D virtual colonoscopy. But whichever method you choose, you'll need the other to confirm the findings. Dr. Judy Yee from the University of California, San Francisco, recently discussed both primary reading methods, and some of the latest study results on 2D versus 3D.July 27, 2006CTStudy: 16-MDCT yields too many nonevaluable artery segmentsLow-dose 16-slice MDCT angiography should not be recommended for the routine nonemergency evaluation of patients with chest pain and an intermediate or high probability of coronary artery disease, according to the authors of a new study in this week's Journal of the American Medical Association.July 25, 2006CTAuntMinnie.com Virtual Colonoscopy InsiderJuly 23, 2006CTWindow levels matter when viewing submerged polyps in VCTagging regimens are increasingly popular among virtual colonoscopy providers, who want to optimize lesion conspicuity and thereby avoid undetected lesions. But finding submerged polyps in 2D means paying careful attention to the attenuation of tagged fluid and window settings, according to new research from the U.K.July 23, 2006CTCanadian lung CAD cuts false positivesAt the Computer Assisted Radiology and Surgery (CARS) conference in Osaka, researchers from Canada presented a CAD algorithm that can distinguish between faint and similarly shaped lung structures, reducing false positives with the aid of a hybrid learning scheme that uses both linear discriminant analysis and fuzzy c-means clustering.July 23, 2006Industry NewsX-ray reveals python's too-hot dinnerA 12-foot Burmese python swallowed an electric blanket -- electrical cord, control box, and all -- but will probably survive to eat another meal. X-ray images show the tangle of the blanket's wiring extending through the python's digestive tract.July 20, 2006CTExtracolonic findings double VC costs, but might be worth payingFollowing up extracolonic findings in virtual colonoscopy can easily double the cost of exams in symptomatic patients, but even the occasional detection of significant pathology may make it cost-effective, researchers from the U.K. report.July 19, 2006Previous PagePage 188 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
