多排螺旋CT在心脏冠状动脉成像中的临床应用价值

目的探讨多排螺旋CT（MSCT）在心脏冠状动脉成像中的临床应用价值。方法回顾本院31例可疑冠心病患者，应用MSCT进行冠状动脉成像检查，其中7例中度以上狭窄者与选择性冠状动脉造影（DSA）检查，并将两种检查结果进行比较。结果对124支冠状动脉进行MSCT血管造影，其中成像血管清晰度优良率达84．7％（105／124），发现不同程度钙化19例，管腔内中度以上狭窄者7例、支架置入术后患者4例，其中支架再发狭窄1例，心肌桥2例，有3名患者进行了重复检查，7例中度以上狭窄患者选择性冠状动脉造影检查结果相符。结论多排螺旋CT冠状动脉成像是一种安全、无创的新型检查方法，在判断冠状动脉狭窄具有较高的特异性及准确性，在冠心病的初步筛选及评价方面具有较高的临床应用价值。

The clinical value of multislice spiral CT in coronary angiography

Objective：To study the clinical value of multislice spiral CT in coronary angiography.Methods：31 patients with suspected coronary artery disease were enrolled with multishce spiral CT,7 patients were found stenosis ≥50%, followed conventional coronary angiography, the results obtained from MSCT were compared. Results： Among the 124 segments satisfied imaging evaluation,19 cases showed small to severe calcification, 7 patients were found stenosis ≥50%, 4 cases done coronary angioplasty with frame insertion, 2 cases showed myocardial bridge. 3 cases done the same examination, 7 cases had identical appearance on both MSCT and DSA. Conclusion：it is suggested that MSCT coronary angiography is a safety and noninvasive examining method with specifical and accurately displaying clinical coronary artery stenoses. MSCT is a valuable method in detecting diseases or variations of coronary artery.
