摘要
Abstract
Objective To evaluate the morphological assessment, accuracy and clinical significance of 320 slice dynamic volume CT (320 - DVCT) in diagnosis of mural coronary artery - myocardial bridges ( MCA - MB). Methods The 320 - slice DVCT scan and coronary angiography (CAG) were performed in 85 patients suspected of coronary artery disease (CAD) for evaluation of the efficacy of DVCT in MCA - MB diagnosis. Results The detection rate of MCA - MB with 320 - slice DVCT was 30. 6％ , among which 82.4％ were located in middle and distal segment of left anterior descending artery. The mean length and thickness of MB were ( 13. 38 +5.06)mm and (3.61 ±2.53)mm, respectively. The incidence of atheroselerosis of MCA - MB adjacent vessels was 96. 2％. Meanwhile, the detection rate of MCA - MB with CAG was 8.2％, which was significantly lower than that with DVCT ( P ＜ 0. 05 ). Conclusion As a new non- invasive approach of assessing MCA - MB, 320 - slice DVCT provides sufficient accuracy and reliability. Furthermore,MCA - MB in patients suspected of CAD is correlated with atherosclerosis.关键词
