Place du coroscanner dans la détection de la maladie coronaire chronique

The use of non-invasive imaging in the diagnosis of chronic coronary diseases is recommended for patients with clinical "intermediary" probability. We discuss the use of several techniques of investigation in relation to clinical signs and results of stress tests. Two different approaches of classification of the coronary disease can be used: the first, anatomical, based on the diameter or luminal reduction of the artery and the second, physiological, based on signs of myocardial ischemia. The coronary CT has recently been introduced in routine practice but official guidelines are still not very precise. This article discusses the use and the diagnostic efficiency of the CT coronary scan in patients with suspected coronary disease.
