Eric Barnes[email protected]CTMeasuring lean body weight can optimize CT contrast doseResearchers at Duke University report that radiologists can minimize contrast dose and optimize enhancement of focal lesions by basing their contrast administration protocols on patients' lean body weight, rather than on total weight.July 21, 2009CTVirtual gastroscopy distinguishes benign from malignant ulcersThree-dimensional CT imaging of the stomach has improved to the point where it's just as useful as endoscopy for differentiating benign from malignant gastric ulcers, albeit with important differences, say researchers from Taiwan.July 20, 2009Digital X-RayProspectively gated coronary CTA nearly equals normal-dose scansResearchers in Italy report that low-dose prospectively gated coronary CT angiography (CTA) scans are nearly equivalent to retrospectively gated exams in diagnostic accuracy, while reducing radiation dose by up to 72%, according to an article published in the Journal of the American College of Cardiology.July 16, 2009CTVC is cost-effective for screening; tiny polyps can be ignoredVirtual colonoscopy is a cost-effective way to screen for colorectal cancer -- provided that individuals with tiny lesions aren't referred for polypectomy, according to the results of a new study from France.July 14, 2009CTRepeated calcium scans increase cancer risk, study findsPatients who undergo repeated coronary artery calcium (CAC) scans may be setting themselves up for a cancer diagnosis, according to a new study that estimated the risks but not the potential benefits of CAC scan protocols and frequencies.July 12, 2009CTVirtual colonoscopy preferred for surveillance follow-upPatients referred for polyp surveillance after virtual colonoscopy are more likely to opt for another VC exam at follow-up, Italian researchers report. But patients want their follow-up scans sooner rather than later.July 9, 2009CTDual-energy CT characterizes fat-containing pathologiesIdentifying fat within lesions is important for narrowing the range of differential diagnoses and potentially avoiding unnecessary intervention. CT and MRI are usually less effective for lesions with low fat concentrations, but would dual-energy CT be better at sussing out fat-containing pathologies? The picture is mixed, according to researchers.July 7, 2009Digital X-RayHigh-pitch cardiothoracic CTA skips breath-holds and high dosesA new way to use CT angiography (CTA) to scan fast-moving targets -- such as fidgety children and grown-ups with rapid heartbeats -- is becoming routine at a hospital in France.July 6, 2009Image ProcessingCARS report: Liver segmentation tool allows manual fixesBERLIN - German researchers believe they have found a better way to preserve the best aspects of automated and manual segmentation in CT liver images, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting.June 30, 2009CTCARS report: New CAD tool follows lung nodules over timeBERLIN - It's easy to complain about the insanity of tracking lung nodule changes in multiple CT scans over time, but at least one group is doing something about it, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting.June 29, 2009Previous PagePage 144 of 258Next PageTop StoriesNuclear MedicineLLMs rapidly evolving in nuclear medicineLarge language models (LLMs) are widely used to handle the large volume of text data generated in nuclear medicine.MRIDWI with fat correction identifies liver scarring in MASLD patientsUltrasoundGhost scans problematic in POCUS trauma examsMolecular ImagingPSMA-PET may require selective use to be cost-effectiveSponsor ContentJoin Us!
