Initial exploration of coronary multi slice spiral CT angiography and selective coronary angiography

Objective To evaluate the feasibility and accuracy of multi slice spiral CT (MSCT) in the detection of coronary artery stenosis. Methods Thirty five patients with suspected coronary artery diseases underwent contrast enhanced MSCT and conventional selective coronary angiography, the outcomes of the two kinds of examination were compared. Results Taking conventional selective coronary angiography as the gold standard, the sensitivity, specificity, and positive and negative prediction values in detecting ≥50% stenotic lesions for assessable segments was 79.4%, 95.7%, 83.1%, and 94.6% , respectively. Conclusion MSCT is capable of achieving high accuracy in detecting coronary artery stenosis, and is a reliable technique in diagnosing coronary artery disease.
