Even small amounts of plaque linked to heart attack, death
By Eric Barnes
A study of nearly 38,000 patients that was published in the Journal of the American Medical Association found that even small amounts of coronary artery plaque increased the risk of heart attack or death a year after diagnosis.

Time-of-flight PET/MRI could help with a variety of clinical applications
By Wayne Forrest
Wednesday, December 3 | 11:10 a.m.-11:20 a.m. | SSK18-05 | Room S505ABTime-of-flight PET/MRI provided comparable image quality and diagnostic ability to PET/CT in several clinical applications in a study from Stanford University.

Chest size swings calcium scores on CT scans
By Eric Barnes
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.

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

Does 4D CTA outperform DSA for arteriovenous malformations?
By Eric Barnes
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.

Is iterative reconstruction a fix for motion-altered calcium scores?
By Eric Barnes
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.

Calcium volume, distribution predict rupture risk for TAVR patients
By Eric Barnes
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.

Motion correction green-lights CCTA in faster hearts
By Eric Barnes
Monday, December 1 | 11:50 a.m.-12:00 p.m. | SSC02-09 | Room S504ABStopping motion in the fast-beating heart is, of course, one of the toughest challenges in radiology, but new methods such as high-pitch CT and motion correction techniques are fueling new levels of image quality, even in patients with the highest heart rates.

Calcium boosts heart attack risk. How about noncalcified plaque?
By Eric Barnes
Monday, December 1 | 11:10 a.m.-11:20 a.m. | SSC02-05 | Room S504ABThe role of coronary artery calcium in myocardial infarction risk is well-established, but the role of noncalcified plaque is still evolving. In this study, researchers aimed to determine how total plaque burden corresponds to traditional risk factors for cardiovascular disease.

3D CT fused with electroanatomic mapping for VT ablation
By Eric Barnes
Sunday, November 30 | 11:55 a.m.-12:05 p.m. | SSA02-08 | Room S502ABA new technique that fuses cardiac CT and electroanatomic mapping could boost the success rate for ventricular tachycardia (VT) mapping and ablation procedures, a more complex process than ablation for atrial fibrillation and related conditions.

Is epicardial fat linked to atrial fibrillation?
By Eric Barnes
Sunday, November 30 | 10:55 a.m.-11:05 a.m. | SSA03-02 | Room S504ABQuantifying epicardial fat on preprocedural CT scans may help identify patients with atrial fibrillation (AF) who will benefit from catheter ablation as a treatment for AF, according to a study to be presented on Sunday.
