Researchers from South Korea wanted to minimize radiation dose but avoid missing a recurrence, so they systematically analyzed the results of different blends.November 5, 2012Image ProcessingCardiac CTA incorporates function, motion analysisWednesday, November 28 | 3:40 p.m.-3:50 p.m. | SSM03-05 | Room S502ABA 64-detector-row scanner can deliver anatomic as well as functional information if you follow the lead of Johns Hopkins University researchers, who used the same data for CT angiography (CTA) and cardiac function, motion analysis, and myocardial perfusion information.November 5, 2012CTTechnologists are quick on the trigger to repeat head scansWednesday, November 28 | 11:10 a.m.-11:20 a.m. | SSK16-04 | Room S403BIn a Canadian study, CT technologists rated head CT image quality lower than radiologists when artifacts were present, making them more prone to repeat scans and expose patients to additional radiation.November 5, 2012CTVirtual high-keV images at DECT cut metal artifactWednesday, November 28 | 11:10 a.m.-11:20 a.m. | SSK11-05 | Room N230Virtual high-keV images of spine hardware at dual-energy CT (DECT) show less artifact and are easier to read than conventional CT images, according to a research team from the University of Michigan.November 5, 2012CT320-slice 4D head CTA derived from CTP replaces extra scanWednesday, November 28 | 8:55 a.m.-9:05 a.m. | VSNR41-02 | Room E451BA new technique can boost the quality of low-dose head CT perfusion (CTP) to the point where it can replace higher-dose 3D CT angiography (CTA), say Dutch researchers, who will explain their findings in this scientific presentation.November 5, 2012CTROMICAT II shows CCTA cuts hospital timeWednesday, November 28 | 8:30 a.m.-8:45 a.m. | VSCA41-01 | Room S502ABThe early use of coronary CT angiography (CCTA) in patients with symptoms suggestive of acute coronary syndromes shortens the length of hospital stay and reduces time to diagnosis, according to researchers from Harvard Medical School and Massachusetts General Hospital.November 5, 2012CTImplementing the ACR's CT dose registryTuesday, November 27 | 3:50 p.m.-4:00 p.m. | SSJ21-06 | Room S403AThe University of Washington has implemented the American College of Radiology's (ACR) CT dose registry, documenting a number of challenges relating to software installation, data transmission, and data consistency issues, most of which have been solved, according to researchers.November 5, 2012Previous PagePage 76 of 258Next PageTop StoriesDigital X-RayChest x-rays reveal atherosclerosis in patients undergoing amputationsLower limb amputation is an increasingly common major complication of advanced peripheral arterial disease and diabetes mellitus.MRI3D MRI technique helps plan treatment for pediatric heart conditionsWomens ImagingCould AI scoring help with managing DCIS?CTClinicians, beware: CT diagnostic accuracy varies by adnexal lesion typePractice ManagementRadiology coding update for 2026
