Low-dose computed tomography coronary angiography with prospective triggering: a promise for the future.

omputed tomography for coronary angiography (CTCA) as rapidly evolved into a valuable alternative to invasive oronary angiography for accurate noninvasive assessment f coronary morphology. Although increasing values of ositive predictive values are continuously reported, it is enerally accepted that the strength of this technology at resent lies in its excellent ability to exclude coronary artery isease (CAD) (i.e., its high negative predictive value). In oncordance, most recommendations (1) consider the use of
