CCTA adds value to ischemic stroke evaluation
By Abraham Kim
Monday, December 2 | 3:40 p.m.-3:50 p.m. | SSE06-05 | Room E353AAcquiring coronary CT angiography (CCTA) in addition to head CT for patients suspected of having an acute ischemic stroke can help identify potential sources of cardioembolic stroke while also providing insight into the patients' risk of coronary artery disease, according to this study to be presented on Monday.

FFR-CT, CCTA bolster emergency chest pain evaluation
By Abraham Kim
Monday, December 2 | 11:20 a.m.-11:30 a.m. | SSC04-06 | Room S102CDThe combination of fractional flow reserve CT (FFR-CT) and conventional coronary CT angiography (CCTA) proved to be effective at ruling out major adverse cardiac events for emergency patients with acute chest pain in this study to be discussed on Monday.

CT whole-heart volume predicts adverse cardiac events
By Abraham Kim
Sunday, December 1 | 11:05 a.m.-11:15 a.m. | SSA03-03 | Room S105ABIndividuals with a small 3D whole-heart volume, as calculated on CT scans, have an increased risk of major adverse cardiac events, compared with those with a normal or large heart volume, according to researchers from Harvard Medical School.
