Computed tomography coronary angiography for screening asymptomatic subjects: a bridge too far?

ultislice computed tomography (MSCT) coronary aniography (CA) has emerged as a powerful noninvasive iagnostic modality to visualize the coronary arteries and the anifestations of coronary atherosclerosis (1). Many reports ave demonstrated that 64-slice computed tomography CT) CA is a viable diagnostic modality to detect or rule out he presence of significant coronary stenoses, but the precise ole of MSCT-CA in the diagnostic work-up of patients ith suspected CAD in relation to existing noninvasive unctional tests (electrocardiogram-stress test, stress–singlehoton emission CT, or dobutamine echocardiography) is ot yet established, and the technique falls short to replace nvasive coronary angiography.
