【摘要】 目的:探讨99mTcMIBI SPECT心肌灌注断层显像(MPI)诊断冠心病(CAD)的临床价值。方法:159例患者,均进行MPI和冠状动脉造影(CAG)检查,将结果进行对比分析。结果:159例中CAD 109例,其他心脏病32例,无器质性心脏病18例。在CAD的诊断中,CAG的敏感性为97.2%;MPI的敏感性为91.7%,特异性为88.9%。结论:CAG和MPI均为诊断冠心病的有效手段。后者由于它的无创性、检查费用低、易于重复,是临床随访的好方法。

Comparison of Myocardial Perfusion Imaging with 99m TcMIBI SPECT and Coronary Angiography in the Diagnosis of Coronary Artery Disease
Abstract: Objective To study the clinical value of 99m TcMIBI SPECT myocardial perfusion imaging (MPI) on diagnosis of coronary artery disease (CAD). Methods One hundred and fiftynine patients underwent both MPI and coronary artery angiography (CAG). All results and clinical data was analyzed. Results 109 cases were diagnosed as CAD, 32 cases as other kinds of heart problem and 18 cases without organic heart disease. The results indicated that for the diagnosis of CAD, the sensitivity of CAG was 97.2%, while the sensitivity and specificity of MPI were 91.7% and 88.9% respectively. Conclusion In this study, both CAG and MP……
