3D printing helps unravel rare cardiac anomalies
By Abraham Kim
A 3D-printed heart model based on patient MR images helped physicians identify two uncommon cardiac anomalies in a case report published online November 11 in Clinical Imaging. The technique may be a viable alternative to more invasive procedures, such as cardiac catheterization, researchers say.

Onsite FFR-CT tops CCTA in detecting coronary stenosis
By Abraham Kim
An onsite fractional flow reserve CT (FFR-CT) algorithm detected functionally significant stenosis in patients suspected of having coronary artery disease with greater accuracy than radiologists reading coronary CT angiography (CCTA) scans in a study, recently published online in Radiology: Cardiothoracic Imaging.

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.
