目的 :通过临床试验对99mTc潘生丁SPECT心肌显像这项无创性检查对诊断冠心病的临床价值进行科学评估。方法 :选择 3 0例可疑冠心病患者 ,首先静脉注射0 5 6mg/kg潘生丁注射液 ,紧接注射 110 0MBq99mTcMIBI ,90min后采集心肌断层图像 ,隔日做蹭车试验。结果 :SPECT检查 9例阳性 ,踏车试验 11例阳性。敏感性和特异性分别为 73 %、94%。结论 :由于该项检查的科学性和无创性 ,具有很高的实用价值 ,可在临床上大力推广。
OBJECTIVE: To evaluate the clinical value of 99mTc dipyridamole SPECT myocardial imaging in the clinical diagnosis of coronary heart disease. Methods: Thirty patients with suspected coronary heart disease were selected. The first injection of dipyridamole (0 5 6mg / kg) was followed by injection of 110 0MBq99mTcMIBI, and the myocardial infarction images were collected 90 minutes later. Results: 9 cases were positive by SPECT and 11 cases by treadmill test. Sensitivity and specificity were 73%, 94%. Conclusion: Due to the scientific and noninvasive nature of the examination, it has high practical value and can be clinically promoted.
