Eric Barnes[email protected]CTMRI sees spinal metastases earlier, but low-dose whole-body MDCT aces skeletal workupResearchers from the University of Munich in Germany produced two studies that put 16-slice MDCT to the test for detecting musculoskeletal tumors. In the first, MRI was far more sensitive than CT for detecting spinal metastases. However, the second study found that ultra-low-dose CT detected 100% of the osteolytic lesions detected at both standard-dose CT and MRI.May 19, 2005CTCAD struggles through tagged, subtracted VC dataRadiologists would love to see a virtual colonoscopy exam so easy it doesn't even need a bowel prep. But to pull it off, they'll need a CAD algorithm that doesn't need a bowel prep either. Researchers from Boston's Massachusetts General Hospital take tentative steps toward an easier VC protocol.May 17, 2005CTConcentrated contrast improves liver lesion conspicuityNew concentrated contrast agents not only improve enhancement of focal liver lesions, they could make imaging safer by reducing contrast volume and flow rates, researchers in France and Germany have concluded.May 15, 2005CTAuntMinnie.com CT Radiology InsiderMay 15, 2005CTVC practice thrives in WisconsinAs debate inches forward in the U.S. over the value of screening virtual colonoscopy, a radiologist in the Midwest has already arranged reimbursement with local payors, and built a thriving practice.May 9, 2005CTRV function scans integrated with chest CTPoor right ventricular function lies at the heart of many chest troubles, and assessing RV function has traditionally required radionuclide ventriculography, echocardiography, or more recently, a dedicated CT scan. But two recent studies looked at preliminary efforts to acquire RV functional information as part of a broader CT evaluation.May 8, 2005CTSupport vector machines boost accuracy of VC CADIt takes a village to raise a child, a famous political wife once wrote. And it seems that carefully chosen groups of advisers can also be beneficial when it comes to computer-aided detection (CAD) features.May 2, 2005CTVC plus vascular views shows invasive colorectal cancerA new study from Japan used vascular views in virtual colonoscopy exams to detect blood pooling related to invasive cancers and small vessels of the colorectal wall. Researchers from the National Cancer Center and National Cancer Center Hospital in Tokyo said their technique will improve radiologists' ability to detect not only colonic polyps, but invasive lesions more accurately.May 1, 2005CTMeta-analysis shows CT is sufficient to exclude PEA negative chest CT exam -- even single-slice -- is enough to rule out pulmonary embolism (PE), according to a meta-analysis published today in the Journal of the American Medical Association.April 26, 2005CTVC study finds thin slices more important than low noiseA new study from Sweden affirms the superiority of thinner CT collimation for detecting colonic polyps, even when constant radiation doses result in noisier images.April 26, 2005Previous PagePage 208 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
