Abstract:
Objective To investigate the accuracy of 64-detector helical CT in assessing stenoses of coronary arteries. Methods 64-detector helical CT angiography was performed in 128 patients with suspected coronary artery disease,and the results were compared with that of invasive coronary angiography. Results Among 128 patients, 1 724 of 1 920 coronary artery segments were assessable (90%). Overall sensitivity for classifying stenoses was 92%, specificity was 94%, positive predictive value was 82%, and negative predictive value was 96%.Conclusion 64-detector helical CT provides a high diagnostic accuracy in assessing coronary artery stenoses.
