But research based on payor data covering millions of patients found that initial evaluation with coronary CT angiography cut costs significantly over a year's time for patients without coronary artery disease and the patient cohort overall.May 29, 2008Cardiac ImagingAuntMinnie.com Cardiac Imaging InsiderMay 26, 2008CTCoronary calcium still mattersIn light of radiology's fervent focus on coronary CT angiography (CTA) and unstable coronary artery plaque, does coronary artery calcium even matter anymore? It does, according Dr. J. Jeffrey Carr of Wake Forest University in Winston-Salem, NC. He recently debunked some myths about calcium at the 2008 International Symposium on Multidetector-Row CT.May 25, 2008CTAutomated polyp measurement cuts variabilityA new study from the Netherlands found that manual polyp measurements in virtual colonoscopy were a bit more accurate than an automated process based on polyp protrusion measurements. The automated scheme still came out ahead, however, because it eliminated interobserver variability.May 20, 2008CTLow tube current, modulation reduce pediatric CTA doseDialing down the x-ray tube current and activating tube-current modulation made a huge difference in the radiation dose for children undergoing coronary CT angiography (CTA), according to a new study in the American Journal of Roentgenology. The reduced-dose acquisition protocols had no significant negative effect on image quality and were, in fact, hardly noticeable, researchers said.May 20, 2008CTCMS launches comment period for VC coverageJust weeks after the American Cancer Society recommended virtual colonoscopy for colon screening, Medicare is taking up the task by launching an analysis of the technology that could eventually lead to U.S. reimbursement for nationwide screening.May 19, 2008Previous PagePage 161 of 258Next PageTop StoriesCTNew benchmark helps monitor cumulative CT radiation doseThe findings highlight the need for systematic dose tracking and rigorous justification of imaging.Radiation Oncology/TherapyStudy questions routine use of radiotherapy after bone surgeryUltrasoundCEUS outshines color Doppler imaging for indeterminate kidney lesionsWomens ImagingWomen's Imaging MinnieCast, Episode 2: Risk-based vs. annual mammography screening, part 1Digital X-RayChest x-rays reveal atherosclerosis in patients undergoing amputations
