目的 探讨螺旋CT造影技术判断 异常血管的应用价值。方法 选择2012年 7月-2014年9月我院收治的冠心病患者 172例作为观察组，同期选择在我院进行 冠状动脉造影的非冠心病患者172例作 为对照组，两组都进行彩色超声分析与 螺旋CT造影判断。结果 观察组的IMT值 明显高于对照组，而SPV、MSV和EDV值 明显低于对照组，对比差异经检验都有 统计学意义(P＜0.05)。观察组多表现为 钙化型与溃疡型斑块，而对照组多表现 为正常、脂质型与纤维型斑块，对比差 异有统计学意义(P＜0.05)。观察组的 狭窄处血管总面积明显高高于对照组(P ＜0.05)。结论 螺旋CT造影技术结合超 声能有效判断冠心病患者的异常血管血 流情况、斑块情况与狭窄情况，从而有 利于进行疾病鉴别与诊断。

Objective To investigate the applying values of spiral CT angiography in the abnormal blood vessels. Methods Selected 172 patients of coronary heart disease from July 2008 to September2014 in our hospital as the observation group, choose 172 notcoronary heart disease patients at the same period in our hospital for coronary angiography as the control group, both groups were given the color ultrasound analysis and spiral CT angiography judgment. Results The IMT value of the observation group were significantly higher, while the SPV, MSV and EDV values were significantly lower than the control group (P＜0.05). The observation group were more showed calcified and ulceration plaques, while the control group were showed more normal, lipid and fibrous plaque that compared difference were statistically significantly (P＜0.05). The total area of the blood vessel stenosis of the observation group were significantly higher (P＜0.05). Conclusion The spiral CT angiography combined with ultrasound can effectively determine abnormal blood flow, plaques and stenosis situation in patients with coronary heart disease which is conducive to the identification and diagnosis of disease.
