On the other hand, if the present case had been associated with a high probability of CAD or inadequate technical conditions (e.g. high ventricular response atrial fibrillation), the scenario could have been different, given that, for a patient with high atherosclerotic burden, the positive predictive value of angio-CT is limited. Furthermore, artifacts caused by an unfavorable situation (AF) may severely impair diagnostic accuracy. In these cases, MPS would be a better form of evaluation. 376
