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.

Imaging vulnerable populations -- the geriatric patient
By Eric Barnes
Tuesday, 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.

How often do pancreatic cysts become ductal adenocarcinomas?
By Eric Barnes
Monday, December 1 | 11:50 a.m.-12:00 p.m. | SSC04-09 | Room E353AThis study evaluated the relationship between pancreatic cysts and pancreatic ductal adenocarcinoma (PDAC), comparing imaging features of the cysts in subjects who subsequently developed PDAC versus those who did not.

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.

Increasing difference in x-ray spectra boosts image quality
By Eric Barnes
Monday, December 1 | 10:50 a.m.-11:00 a.m. | SSC12-03 | Room S403BThis study from the Mayo Clinic in Rochester, MN, showed that increasing the difference in the x-ray spectra in dual-energy CT increases image quality, and that this improvement can be translated into reductions in dose.

Monoenergetic reconstruction tool boosts pancreatic tumor conspicuity
By Eric Barnes
Monday, December 1 | 10:30 a.m.-10:40 a.m. | SSC04-01 | Room E353AIn pancreatic cancer imaging, conventional methods produce only very faint enhancement differences. Researchers from Germany are finding pancreatic lesions much easier to see using a monoenergetic reconstruction algorithm plus dual-source CT.

Organ-dose software results are highly variable
By Eric Barnes
Monday, December 1 | 10:30 a.m.-10:40 a.m. | SSC12-01 | Room S403BConcerns over radiation dose in CT have led to the development of dose tracking software that estimates organ doses, replacing tedious manual processes. How well do they work? Dr. Atul Padole and colleagues evaluated two software packages.

Effective assessment of lung cancer treatment response
By Eric Barnes
Monday, December 1 | 8:30 a.m.-10:00 a.m. | RC218 | Room N226A multispeaker course on treatment response for several kinds of cancer begins at 8:30 a.m. with a talk by Dr. Elena Korngold on a practical perspective of reporting treatment response. Arrive by 9:30 a.m. for the last talk in the series by Dr. Jeremy Erasmus from MD Anderson Cancer Center, who will focus on lung cancer.

Advanced imaging unveils secrets of ancient artifacts
By Eric Barnes
Sunday, November 30 | 2:00 p.m.-3:30 p.m. | RC124 | Room N226A review course taught by Dr. Barry Daly from the University of Maryland will cover a wide range of artifacts, including Egyptian and Peruvian mummies, Mesoamerican and Chinese ceramics, Mesopotamian stucco art, Judaic tabernacles, and European medieval religious artifacts.

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.

Single- vs. dual-energy abdominal CT: Which has the lowest dose?
By Eric Barnes
Sunday, November 30 | 11:45 a.m.-11:55 a.m. | SSA06-07 | Room E353ATriple-phase liver exams are a good way to evaluate CT dose. But which generates the lowest doses: single- or dual-source scanning? This study compared dose levels in 45 patients who had undergone the exam on different occasions with different scanners.
