CT best for ruling out CAD

Computed tomography (CT) is a better non-invasive imaging test than magnetic resonance imaging (MRI) for detecting and ruling out coronary artery disease, a meta-analysis shows. The analysis included 89 CT studies and 19 MRI studies directly comparing the noninvasive imaging test with conventional coronary angiography. The sensitivity and specificity for CT was 97.2% and 87.4%, respectively, and 87.1% and 70.3%, respectively, for MRI, the study authors found. "CT should be considered the foremost noninvasive alternative to coronary angiography in selected patient populations,” they concluded....
