Coronary angiography is the reference standard to confirm the presence and severity of coronary stenoses. Given the invasiveness of this procedure, a noninvasive mean allowing to visualize coronary anatomy would be of obvious clinical interest. Multidetector spiral computed tomography and magnetic resonance imaging are new and promising techniques for noninvasive detection of significant coronary stenoses. The purpose of this article is to review the present knowledge on these noninvasive techniques.
