Eric Barnes[email protected]CTCTA dose and image quality: 3rd- vs. 2nd-generation DSCTThursday, December 4 | 9:35 a.m.-9:45 a.m. | VSVA51-06 | Room E352How much can dose be reduced in CT angiography (CTA) while preserving image quality in the latest dual-source CT (DSCT) scanners? Dr. Florian Schwarz and colleagues from the University of Munich looked at the image quality and radiation dose-saving potential of advanced dual-source CT.November 3, 2014CTKnee perfusion is key in limb salvage after traumaWednesday, December 3 | 3:50 p.m.-4:00 p.m. | SSM25-06 | Room E450BTrauma patients are typically assessed for salvageability of lower limbs based on a clinical exam and perfusion assessment of the distal arteries. But a group from Texas found that flow in the geniculate artery on CT angiography studies is crucial in determining whether such patients will eventually need an amputation.November 3, 2014CTDoes 4D CTA outperform DSA for arteriovenous malformations?Wednesday, December 3 | 3:00 p.m.-3:10 p.m.| SSM25-01 | Room E450BDigital subtraction angiography (DSA) is the gold standard for evaluating arteriovenous malformations, but 4D CT angiography (CTA) outperforms it by visualizing the nidus.November 3, 2014CTStudy finds ultralow-dose CTC equivalent to normal-dose scansWednesday, December 3 | 11:50 a.m.-12:00 p.m. | SSK08-09 | Room E351The need for dose reduction is real in CT colonography (CTC), an exam that could be repeated several times between ages 50 and 80 years, when colorectal cancer screening is recommended. Fortunately, the University of Rome La Sapienza is on the case, working to reduce the dose for CTC to sub-mSv levels consistently.November 3, 2014Image ProcessingIs iterative reconstruction a fix for motion-altered calcium scores?Wednesday, December 3 | 11:50 a.m.-12:00 p.m. | SSK03-09 | Room S502ABDr. Martin Willemink and colleagues from University Medical Center Utrecht in the Netherlands addressed this question with iterative model reconstruction, a calcium hydroxyapatite-containing phantom, and a 256-slice CT scanner.November 3, 2014CTCT colonography keynote: Present and futureWednesday, December 3 | 10:30 a.m.-10:50 a.m. | SSK08-01 | Room E351CT colonography (CTC) expert Dr. Abraham Dachman will start off this year's CTC scientific sessions with a talk on the present and future of the technique.November 3, 2014CTRefresher course examines imaging for traumatic brain injuryTuesday, December 2 | 4:30 p.m.-6:00 p.m. | RC405 | Room E451AA Tuesday refresher course on traumatic brain injury will present three speakers beginning at 4:30 p.m. First, Dr. Paul Parizel, PhD, will discuss the use of CT and MR for patients with head trauma.November 3, 2014Image ProcessingStudy compares 2nd, 3rd generations of iterative reconstructionTuesday, December 2 | 10:50 a.m.-11:00 a.m. | SSG04-03 | Room E350Liver lesions are always a challenge to visualize with CT, and iterative reconstruction improves conspicuity in the liver and other regions. How does the latest algorithm stack up against an earlier iteration?November 3, 2014CTCalcium volume, distribution predict rupture risk for TAVR patientsTuesday, December 2 | 10:30 a.m.-10:40 a.m. | SSG02-01 | Room S504ABBalloon-expandable transcatheter aortic valve replacement (TAVR) procedures can lead to dangerous aortic root injury in the event of annular rupture. How do such ruptures happen and in which patients? Canadian researchers looked at the role of calcified plaque's location and distribution in these events.November 3, 2014CTImaging vulnerable populations -- the geriatric patientTuesday, December 2 | 8:30 a.m.-10:00 a.m. | RC308 | Room S502ABA special course on imaging vulnerable populations will begin at 8:30 a.m. and feature studies on several vulnerable patient groups for which CT plays an important role. Arrive by 9:30 a.m. to hear our highlighted presentation on geriatric patients, presented by Dr. Claudia Sadro.November 3, 2014Previous PagePage 43 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
