CT ownership growth among otolaryngologists and neurologists: Major trend?

Friday, December 5 | 11:00 a.m.-11:10 a.m. | SST10-04 | Room N227Ear, nose, and throat (ENT) physicians and neurologists are among the physician groups increasingly putting CT scanners in their offices -- bypassing radiologists for in-office exams. How common is the trend?

Chest size swings calcium scores on CT scans

Friday, December 5 | 10:50 a.m.-11:00 a.m. | SST03-03 | Room S504ABDoes chest size, since it is related to obesity, affect calcium scores? Dutch researchers aimed to find out, having previously found an association between obesity and coronary calcium scores, and shown that CT image quality deteriorates with increased body weight.

CT aims for takeover of scintigraphy in GI bleeding

Thursday, December 4 | 11:00 a.m.-11:10 a.m. | SSQ07-04 | Room E353AAcute lower gastrointestinal bleeding (GI) is a medical and surgical emergency that can lead to significant morbidity and mortality. But how should physicians detect where it comes from? CT does it best, researchers from Pakistan will report in this presentation.

CTA dose and image quality: 3rd- vs. 2nd-generation DSCT

Thursday, 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.

Knee perfusion is key in limb salvage after trauma

Wednesday, 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.

Does 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.

Study finds ultralow-dose CTC equivalent to normal-dose scans

Wednesday, 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.

Is 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.

CT colonography keynote: Present and future

Wednesday, 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.

Refresher course examines imaging for traumatic brain injury

Tuesday, 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.

Study compares 2nd, 3rd generations of iterative reconstruction

Tuesday, 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?

Calcium volume, distribution predict rupture risk for TAVR patients

Tuesday, 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.
