摘　　要：目的探讨冠状动脉疾病诊断中放射CT血管造影的作用。方法选取冠状动脉疾病行放射CT血管造影的患者50例，经扫描心电门控技术完成钙化结节检查，按1、3mm不同层厚对原始数据重建。结果1mm组检出的钙化斑块数、相关敏感度、检出小钙化斑块数、相关敏感度均高于3mm组，差异有统计学意义（P〈0．05）。结论放射CT血管造影在冠状动脉疾病诊断中运用心电门控技术对钙化斑块检测时，相较3mm层厚，1mm可有更多钙化斑块检出，特别是小钙化斑块，故对钙化斑块的确定有非常重要的意义，为临床诊断提供了有力的参考依据，并辅助疾病治疗，是保障患者预后改善的强有力的保障。Objective To investigate the role of radiology CT angiography in diagnosis of coro- nary artery disease. Methods Fifty patients with coronary artery disease underwent radiology CT angiog- raphy were selected. They received calcification positive inspection by cardiac gating techniques, and raw data were reconstructed according to different thickness such as 1 mm and 3 ram. Results The number of detected calcified plaque and the related sensitivity, the number of detected small calcified plaque and the related sensitivity in 1 mm group were higher than 3 mm group; the differences were statistically sig- nificant （P 〈 0. 05 ）. Conclusions In the diagnosis of coronary artery disease with radiology CT angiog- raphy, 1 mm group can detect more calcified plaque, especially small calcified plaque when tested with cardiac gating techniques, so the radiology CT angiography is very important to determine calcification plaque. It provides strong references and can guarantee the prognosis.
