Answer

Multidetector computed tomography (MDCT) coronary angiography may be considered as an alternative to invasive angiography to exclude ACS when there is a low to intermediate likelihood of CAD and when cardiac troponin and/or ECG results are inconclusive. [61]  This imaging modality can be used in the emergency department for triage of patients with chest pain. [62]
