Ridley[email protected]UltrasoundUltrasound performs well in meniscal tearsUltrasound can accurately diagnose meniscal tears, yielding results that correlate well with MRI findings, according to researchers from South Korea. They found that ultrasonography can be a useful alternative to MRI in selected cases of meniscal tears.February 4, 2008AIAuntMinnie.com Advanced Visualization InsiderJanuary 29, 2008UltrasoundBreast sonoelastography aids in evaluating breast lesionsReal-time breast sonoelastography supports other imaging modalities in the evaluation of breast lesions, and shows promise for reducing biopsy rates, according to results from an Italian multicenter study. Researchers performed high-resolution ultrasound and sonoelastography on 784 women with a total of 874 lesions.January 27, 2008PACS/VNAPDAs may be suitable for viewing trauma head CTA personal digital assistant (PDA) with a high-resolution display offers similar performance compared to a diagnostic workstation for reporting the presence of an acute intracranial hemorrhage, according to a study by researchers in Ireland. The study included 30 noncontrast cranial CT cases, with images viewed on a PDA and a 3-megapixel display.January 24, 2008UltrasoundAuntMinnie.com Ultrasound InsiderJanuary 22, 2008PACS/VNAMagnification matters for lesion trackingWhen viewing comparison images, the magnification of one image compared to another can affect radiologists' ability to perceive lesion growth, according to researchers from the University of Alabama at Birmingham (UAB). Using 90 pairs of CT images depicting well-defined, hypodense liver lesions, the team sought to determine the effect of the magnification of one image on lesion comparison over time.January 20, 2008PACS/VNAAuntMinnie.com PACS InsiderJanuary 15, 2008PACS/VNALossy compression performs well in abdominal CT imagesLossy compression techniques are effective in abdominal CT exams at a range of compression ratios, according to a pair of recent studies. Researchers in Austria judged 3D JPEG 2000 to be suitable at ratios up to 15:1, while a South Korean team found 5:1 JPEG 2000 to be visually lossless.January 15, 2008BreastMammo CAD results show reproducibility in serial examsThe sensitivity and reproducibility of computer-aided detection (CAD) software is consistently high for breast cancer detection in both initial and short-term follow-up digital mammograms, according to research published in the January issue of Radiology.January 9, 2008UltrasoundComprehensive musculoskeletal US exam offers most valueWhile a focused musculoskeletal sonographic exam can identify most abnormalities, a protocol-based exam allowed for identification of 98% of symptomatic abnormalities in a recent retrospective study, according to researchers from the University of Michigan Hospitals in Ann Arbor.January 2, 2008Previous PagePage 285 of 393Next 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
