摘　　要：目的探讨多排螺旋CT心肌灌注诊断冠心病缺血心肌的应用价值,为今后临床诊治提供参考和借鉴。方法本研究选取我院2011年4月至2013年5月期间收治的经核素灌注显像确诊为可逆性心肌缺血冠心病患者26例(观察组)及正常人15例(对照组),所有病例均行多排螺旋CT心肌灌注诊断,根据静息、负荷灌注心肌图像的变化来评价两组病例的心肌灌注缺损性质,测量心肌密度,对比分析两组的测量结果。结果对照组于静息及负荷下所对应的扫描期点心肌密度测量值对比无显著性(P>0.05),差异无统计学意义;观察组于静息及负荷下所对应的扫描期点心肌密度测量值对比有显著性(P<0.05),差异有统计学意义;观察组与对照组除了在平扫、静息延迟30s期点扫描的心肌密度测量值对比无显著性(P>0.05),差异无统计学意义,其余各期点的心肌密度测量值对比均有显著性(P<0.05),差异均有统计学意义。结论多排螺旋CT心肌灌注诊断能有效地鉴别可逆性心肌灌注异常,与核素灌注显像诊断结果具有较高的一致性,可为缺血性心脏病临床诊治提供准确的心肌循环血流信息,具有较好的临床应用价值,值得在实践中广泛的应用和推广。Objective To explore the application value of multislice helical ct myocardial perfusion in diagnosis of coronary heart disease ischemic myocardium and provides a reference for future clinical diagnosis and treatment. Methods This study selects the 26 reversible myocardial ischemia coronary heart disease patients who were diagnosed through nuclein perfusion imaging and were treated in our hospital from April 2011 to May 2013. They are the observation group. The control group includes 15 cases of normal people. All cases are diagnosed by multislice helical CT myocardial perfusion. According to the changes of resting load perfusion images,the study evaluates the myocardial perfusion defect nature and measures the myocardial density of cases in the two groups. Finally the study compares and analyzes the measuring results of the two groups. Results The contrast of the scanning stage myocardial density measurements corresponding to the resting and load in the control group is not significant（ P〉0. 05）. The difference is not statistically significant. The contrast of the scanning stage myocardial density measurements corresponding to the resting and load in the observation group is significant（ P〉0. 05）. The difference is statistically significant. The contrast of myocardial density measurements in the plain scan and resting late 30 s scan of the observation group and the control group is not significant（ P〉0. 05）. The difference is not statistically significant. The contrasts of myocardial density measurements in the rest period are significant（ P〈0. 05）. The differences are statistically significant. Conclusion Multislice helical ct myocardial perfusion diagnosis can identify the abnormalities of reversible myocardial perfusion effectively. It has high consistency with the diagnosis results of nuclein perfusion imaging. It can provide accurate myocardial circulation blood flow information. It is of high value in clinical application and is worthy applying and be promoted widely in practice.
