Abstract

　　Objective：To perspective scan the atheromatous calcification of coronary artery using Toshiba Aquilion M16 spiral CT. The objective of this study was to accurately score the extent of coronary artery calcification.

　　Methods：coronary artery scanned by means of ECG－gsted technology within the cardiac diastotic phase，and the data acquired by reconstructive image with ECG technique. The calcification scoring was using the software of Agatston score.

　　Results：In 128 patients underwent the examination，coronary arterial image of 96 cases showed satisfied，the images of 27 patients showed not very satisfied，and the images in 5 patients could not make the clinical diagnosis.

　　Conclusions：When the heart rate between 60－80 times per minute，the coronary artery image was the most satisfied，and the calcification scoring was accurate. Therefore，the MSCT was a noninvasive method in screen of coronary arterial calcification，and can provide strongly evidence for clinic diagnosis.
