摘要
目的分析冠状动脉狭窄诊断中SPECT负荷核素心肌灌注显像与CT冠状动脉造影联合应用的互补效果。方法回顾分析40例2018年10月至2019年10月期间的冠状动脉狭窄患者临床资料,所有患者均接受CTCA和MPI检查,比较不同方法对冠状动脉狭窄诊断的效果。结果CTCA诊断为阳性32例,MPI检查结果为阳性33例,其阳性率分别为80.0%和82.5%,CTCA与MPI联合诊断的阳性率为95.0%,与单独CTCA或MPI阳性检出率比较差异具有统计学意义(p<0.05)。结论CTCA或MPI联合应用于冠状动脉狭窄诊断,能够充分发挥这两种检查方法的优势,互为补充,从而提升临床对冠状动脉狭窄的诊断效率。
Objective To analyze the complementary effects of SPECT-loaded nuclide myocardial perfusion imaging and CT coronary angiography in the diagnosis of coronary stenosis.Methods The clinical data of 40 patients with coronary artery stenosis from October 2018 to October 2019 were retrospectively analyzed.All patients were examined by CTCA and MPI to compare the diagnostic effects of different methods on coronary artery stenosis.Results The CTCA was diagnosed in 32 cases,and MPI was positive in 33 cases.The positive rates were 80.0%and 82.5%,respectively.The positive rate of combined CTCA and MPI diagnosis was 95.0%,compared with the positive detection rate of CTCA or MPI,the difference was significant(p<0.05).Conclusions The combined use of CTCA or MPI in the diagnosis of coronary artery stenosis can give full play to the advantages of these two methods and complement each other,thereby improving the clinical diagnosis efficiency of coronary artery stenosis.
