Better guidelines are needed to increase the modality's value in breast imaging, according to a presenter at the 2006 American Society of Breast Disease (ASBD) symposium in Las Vegas.May 25, 2006CT64-slice CT reliable as first-line test before coronary angiographyIn two of the first studies comparing generations of CT systems, 64-slice scanners appear to be the most accurate in detecting coronary vessel obstruction. The studies, presented at the 2006 American College of Cardiology (ACC) meeting in Atlanta, found clinically significant differences among 12-, 16-, and 64-slice scanners.May 24, 2006Page 1 of 1Top 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
