[CT coronary angiogram: state of the art in 2009].
Thanks to 64 multi-detector CT-scan it is nowadays possible to visualise non invasively the coronary arteries: the recently published series have shown excellent sensitivity and specificity in the detection of coronary artery disease. Actually, the principal interest of the technique is the excellent negative predictive value which is very useful to rule out a significant coronary artery stenosis. For the time being, the angio CT is recommended for symptomatic patients with low to intermediate probability of coronary artery disease with inconclusive functional test. Despite some technical ameliorations, the irradiation doses delivered by multi-detector CT are significant and should restrict its indications specifically in women and young patients, in whom a late radio-induced cancer may be a concern.
