目的通过分析64层螺旋CT冠状动脉狭窄程度判断不准确原因,以期提高诊断准确性。方法回顾性总结160例临床怀疑冠状动脉粥样硬化性心脏病并同期接受64层螺旋CT冠状动脉造影及常规冠状动脉造影的病例,计算64层螺旋CT冠状动脉造影狭窄程度高估及低估所占比例并分析常见原因。结果 64层螺旋CT冠状动脉造影评估血管段狭窄程度高估占12.8%,低估占5.8%。判断不准确常见原因为较严重钙化、图像质量欠佳及医师诊断经验不足。结论 64层螺旋CT冠状动脉造影狭窄程度判断准确性与多种因素有关,多方面共同努力可有效提高判断准确性。
Objective To analyze the 64-slice spiral CT coronary artery stenosis to determine the inaccurate causes in order to improve the diagnostic accuracy. Methods A retrospective review of 160 cases of suspected coronary atherosclerotic heart disease and concurrent 64-slice spiral CT coronary angiography and conventional coronary angiography in patients with computed tomography 64-slice spiral CT coronary angiography over-estimated and underestimated the share of Proportions and analyze common causes. Results 64-slice spiral CT coronary angiography assessment of vascular stenosis overvalued accounted for 12.8%, underestimation accounted for 5.8%. Common causes of inaccurate judgment are more severe calcifications, poor image quality, and inadequate physician diagnostic experience. Conclusion The accuracy of 64-slice spiral CT coronary angiography is related to many factors. The joint efforts of many aspects can effectively improve the accuracy of the judgment.
