目的 旨在探讨256排螺旋CT后处 理容积再现技术在冠心病诊断中的应用价 值。方法 选取我院2016年6月-2017年11 月收治的冠心病患者63例，患者均经冠状 动脉造影检查确诊为冠心病，63例患者均 进行了CT检查并进行容积再现后处理，收 集患者影像学资料，以冠状动脉造影检查 结果为对照，计算256排螺旋CT后处理容 积再现技术对冠心病的检出率及诊断准确 率。结果 容积再现技术对冠心病的检出 率及诊断准确率分别为98.41%(62/63)、 96.82%(61/63)，其中对轻度狭窄检出 率、诊断准确率为94.73%、89.47%，中 度狭窄检出率、诊断准确率为100%、 96.00%，对重度狭窄及血管闭塞检出率、 诊断准确率均为100%。结论 256排螺旋CT 后处理容积再现技术可有效显示冠心病患 者血管狭窄情况，并可对患者血管狭窄进 行相应准确诊断，为临床后期制定治疗方 案提供影像学资料。

Objective To explore the value of 256-slice CT postoperative volume rendering in the diagnosis of coronary heart disease. Methods 63 cases of coronary heart disease patients treated in our hospital from June 2016 to November 2017 were selected. Those 63 cases patients were conducted CT examination and volume rendering treatment, their imaging data was collected. By the comparison with the results of coronary angiography examination, 256-slice CT volume rendering technique on the detection rate and diagnosis accuracy of coronary heart disease (CHD). Results The detection rate and diagnostic accuracy of volume reproduction technology for coronary heart disease were 98.41% (62/63) and 96.82% (61/63) respectively, among which the detection rate and diagnostic accuracy for mild stenosis were 94.73% and 89.47% respectively. Conclusion 256-slice CT postoperative volume rendering can effectively show the vascular stenosis in patients with coronary heart disease, and can accurately diagnose the vascular stenosis in patients with coronary heart disease, providing imaging data for the formulation of treatment plans in the later stage of clinical practice.
