目的 对冠状动脉非钙化斑块的 CT影像特征进行详细的研究和分析。方 法 对我院2010年2月-2016年7月期间确诊 为冠心病患者120例，对其进行回顾性分 析。结果 120例患者中存在非钙化斑块一 共52块，在非钙化斑块在冠状动脉狭窄程 度中的分布情况为：轻度15个(28.84%)， 中度23个(44.23%)，重度14个(26.92%)； 主要以冠状动脉左边的前室间支和右边的 冠状动脉所占的比例为主；在剩下的三 支分支中所占比例较少；在统计的血管 狭窄阻塞数据中非钙化斑块明显比钙化斑 块和混合斑块所占比重多，采用软件检 测得出三类关系差别具有统计学意义(P ＜0.05)。结论 CT扫描检查对临床上的冠 状动脉粥样硬化性心脏病患者具有诊断价 值和指导意义。

Objective To investigate the CT imaging feature analysis of coronary artery noncalcified plaques. Methods 120 cases with coronary artery in our hospital from February 2010 to July 2016 were selected and retrospectively analyzed. Results Of 120 cases, 52 existed noncalcified plaques, distributed situation were: 15 mild (28.84%), 23 moderate (44.23%), 14 severe (26.92%), mainly anterior interventricular branch on left of coronary artery and right coronary artery, account less of other three branches. Noncalcified plaques account more than calcified plaque and mixed plaques from vascular stenosis block data, the difference of the three types were statistically significant (P<0.05). Conclusion Computed tomography ct scan has diagnosis value and guiding significance on coronary atherosclerotic cardiopathy.
