[Noninvasive imaging techniques to study coronary artery aneurysms].

Given the growing evidence about the use of membrane-covered stents to treat coronary artery aneurysms, it is fundamental to know the exact anatomy of the aneurysm to enable patients to be selected correctly. Invasive heart catheterization has limitations for diagnostic purposes and can underestimate the size of the aneurysm. In this article, we review the noninvasive diagnostic imaging techniques for the study of coronary artery aneurysms, illustrating the usefulness of each technique.
