Abstract
Background: Multislice CT coronary angiography is a recent technique used to diagnose coronary artery diseases with better spatial and temporal resolution.
Objectives: To detect stenosis in the coronary arteries using thin slice multidetector row CT coronary angiography.
Methods: A total number of 15 patients scheduled for elective conventional coronary angiography for known or suspected coronary artery disease were enrolled for multislice CT angiography of the coronary arteries 5 patients with previous CABG operation and other 3 patients with percuta-neous trans-luminal coronary angioplasty (PTCA) and stenting were included.
Results: CT coronary angiography detected significant and non-significant stenoses in the native arteries and evaluated the patency of the grafts, conduits and stents in post interven-tional cases.
Conclusion: The improved spatial and temporal resolution of the CT coronary angiography makes it capable of detecting stenosis in the coronary arteries, diagnosing coronary artery anomalies and proper evaluation of the grafts and stents.
