Results of Clinical Studies

This chapter summarizes the diagnostic performance of cardiac CT. The method has high sensitivity for detecting stenosis in native coronary arteries and can be used to reliably rule out disease in patients with low-to-intermediate pretest likelihood. CT is suited for detecting coronary artery bypass graft occlusion. In patients with stents, high rates of nondiagnostic studies and relatively poor positive predictive value limit the use of cardiac CT. Studies show high agreement of CT with magnetic resonance imaging in cardiac function assessment.
