目的评价16层螺旋CT冠状动脉造影对冠状动脉病变的诊断价值。方法对80例冠心病(76例拟冠心病患者,4例冠状动脉支架及搭桥术后患者)行多层螺旋CT(MSCT)增强扫描及后处理。结果80例中共显示斑块204处,其中硬斑块128处,软斑块96处,尤以左前降支为最多;冠状动脉狭窄共60例,其中轻度狭窄36例,中度狭窄16例,重度狭窄8例,仍以左前降支为多。心脏肿瘤3例,中纵隔囊肿1例,主动脉夹层3例,真性动脉瘤1例,大血管畸形3例。结论16层螺旋CT对冠状动脉狭窄程度,斑块性质的评价,具有较高的应用价值,是安全、准确、可靠的冠心病诊断方法。
Objective To evaluate the value of 16-slice spiral CT coronary angiography in the diagnosis of coronary artery disease. Methods Eighty patients with coronary heart disease (76 patients with suspected coronary artery disease, 4 patients with coronary artery stenting and postoperative bypass grafting) underwent multi-slice spiral CT (MSCT) enhanced scan and post-treatment. Results There were 204 plaques in 80 cases, of which there were 128 plaques and 96 soft plaques, especially the left anterior descending branch. There were 60 cases of coronary stenosis, including 36 cases of mild stenosis and 16 cases of moderate stenosis , Severe stenosis in 8 cases, still more left anterior descending. 3 cases of cardiac tumor, 1 case of mediastinal cyst, 3 cases of aortic dissection, 1 case of true aneurysm and 3 cases of macrovascular malformations. Conclusion The evaluation of 16-slice spiral CT in the evaluation of coronary artery stenosis and plaque quality is of high value and is a safe, accurate and reliable method for the diagnosis of coronary heart disease.
