目的探讨对冠状动脉疾病使用核素心肌灌注显像与64层螺旋CT的诊断价值,以供临床对冠心病等疾病诊断给予参考和借鉴。方法对我院2010年8月～2011年7月收治的70例疑似冠状动脉疾病的患者分别采用核素心肌灌注显像与64层螺旋CT诊断,患者两种方法检查时间间隔在1个月内。以冠状动脉造影为诊断金标准。比较两种方法对患者的检出率。结果使用核素心肌灌注显像对70例患者的检出率为78.57%(55/70),其诊断准确性为81.43%(57/70);64层螺旋CT对患者的检出率为80.00%(56/70),其诊断准确性为82.86%(58/70),两种方法的检出率和准确性比较均无明显差异,P>0.05,差异无统计学意义。结论使用核素心肌灌注显像与64层螺旋CT均能够为患者给予较好的诊断,且两种方法的诊断检出率和准确率无差异,医生可根据患者的实际情况为其选择诊断方法,还可以联合使用此两种方法,以提高检出率。
Objective To investigate the diagnostic value of myocardial perfusion imaging and 64-slice spiral CT in the diagnosis of coronary artery disease (CAD) for the clinical diagnosis of coronary heart disease and other diseases. Methods Seventy patients with suspected coronary artery disease admitted from August 2010 to July 2011 in our hospital were diagnosed by radionuclide myocardial perfusion imaging and 64-slice spiral CT respectively. The patients’ examination interval was within 1 month . Coronary angiography for the diagnosis of gold standard. Compare the detection rate of the two methods to patients. Results The detection rate of myocardial perfusion imaging in 70 patients was 78.57% (55/70), and the diagnostic accuracy was 81.43% (57/70). The detection rate of 64-slice spiral CT was 80.00 % (56/70). The diagnostic accuracy of the two methods was 82.86% (58/70). There was no significant difference between the two methods in the detection rate and accuracy, P> 0.05, the difference was not statistically significant. Conclusion Both myocardial perfusion imaging and 64-slice spiral CT can provide a better diagnosis for the patients, and there is no difference between the two methods in diagnosis and accuracy. According to the actual situation of the patients, doctors can choose the diagnosis method , You can also use a combination of these two methods to improve the detection rate.
