Eric Barnes[email protected]MRIMRI histogram analysis predicts bladder tumor aggressivenessSophisticated histogram-based measurements of diffusion on MRI scans can predict bladder tumor aggressiveness noninvasively, according to a new study in Abdominal Imaging. The results could potentially help clinicians tailor therapy to individual patients, and even help predict which patients' tumors will metastasize.August 14, 2014CTStudy shows combined thoracic CT use has droppedCombined CT scans of the thorax -- which Medicare has been keeping an eye on -- aren't being overused after all. In fact, use of the combined scans is low and falling over time, according to a new study in the Journal of the American College of Radiology.August 13, 2014Nuclear MedicineCirculation: Little radiation risk seen in cardiac scansA lack of demonstrated harms combined with significant recent dose reductions have led at least one group of cardiovascular imaging specialists to worry less about the risks of a heart scan and more about the well-being of the patient, according to a new review article in Circulation.August 10, 2014CTAutomated CT tool reveals pulmonary hypertensionIn a new study that used computer-aided analysis, the presence of low normal lung tissue volume correlated with pulmonary arterial hypertension at 3D CT. The technique could offer a more accessible and less invasive diagnostic test than right heart catheterization, according to researchers from Japan.August 7, 2014ISCerner buys Siemens IT; ICR goes big; MRI appropriateness; iterative reconAugust 6, 2014CTDo homework before plugging in CT iterative reconstructionImplementing iterative reconstruction on your CT scanner is more than just turning the thing on: You need a careful stepwise approach to get the most out of the radiation dose reduction technology, according to Dr. Jeffrey Mendel. In fact, a full review of your institution's CT protocols could be in order.August 5, 2014CTCT shows Egyptian heart disease hasn't changed in millenniaCT scans of coronary artery calcium in modern Egyptians revealed that they had patterns of atherosclerosis nearly identical to those of ancient Egyptian mummies -- right down to the affected anatomy, according to a new study in Global Heart.August 3, 2014CTAuntMinnie.com CT InsiderJuly 30, 2014CTCT lung screening participants not bothered by false positivesParticipants in the massive National Lung Screening Trial weren't troubled by false-positive initial results suggesting they might have cancer -- possibly because they had been well-prepared in advance for such alarms, according to a report published on Friday in Cancer.July 24, 2014Digital X-RayStudy: Nonobstructive coronary disease has its own risksIndividuals found to have nonobstructive plaque at angiography are routinely sent home without being stented. But a new study from Colorado suggests that simply dismissing these patients and hoping for the best could be dangerous.July 17, 2014Previous PagePage 48 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
