ObjectiveTo evaluate the CT features of coronary artery aneurysm by coronary artery imaging on 128 slice CT and dual source CT (CTCA).
MethodsA total of 1 108 cases were prospectively examined using CTCA between March 2011 and April 2014. With volume rendering, maximum intensity projection, multiplanar reconstruction and surface reconstruction, we observed the coronary artery morphology and vascular wall condition.
ResultsThree cases of coronary artery aneurysm were found. In case one, the anterior descending branch (LAD) had grape-like prominency segmentally; in case two, LAD and left coronary circumflex branch (LCX) and right coronary artery (RCA) had diffuse dilation with local shuttle expansion; in case three, left main, LAD and LCX and RCA had diffuse expansion.
ConclusionCTCA is a noninvasive, simple and effective method for the diagnosis of coronary artery aneurysm, and it can be the first choice for the high risk population with coronary artery aneurysm.
