Coronary artery visualization using a 64-row multi-slice computed tomography in unselected patients with definite or suspected coronary artery disease: a comparison with invasive coronary angiography.

Background: Multi-slice computed tomography (MSCT) is becoming an increasingly acknowledged means of visualizing coronary arteries. The accuracy of 64-MSCT is still a subject of clinical evaluation. Our study, performed with a 64-slice scanner, was intended to assess the concordance of coronary artery lumen visualization in MSCT and invasive coronary angiography (ICA), both in post-revascularization and previously medically treated patients.
