Abstract：Objective To review the clinical values of real-time myocardial contrast echocardiography (RT-MCE) and delayed-enhancement magnetic resonance imaging (DE-MRI) in detection survival myocardium. Methods The patients with coronary heart disease (CHD,n=27, male 16, female 11 and average age, 62.5) were chosen from July 2012 to Dec. 2013. All patients were given treatment of RT-MCE, DE-MRI, coronary angiography (CAG) and percutaneous coronary intervention (PCI). The images of RT-MCE were analyszed by using visual semi-quantitative method for deciding survival myocardium. DE-MRI was graded and survival status of myocardium was adjuged according to the grading results. All patients were given reexamination of RT-MCE after 1 m, 3 m and 6 m respectively. The improvement of ventricular segment systolic function after coronary revascularization was taken as the gold standard for deciding survival myocardium.Results The sensitivity, specificity and accuracy of semi-quantitative RT-MCE were, respectively, 70.9%, 85.7% and 76.3% and those of DE-MRI were, respectively, 72.7%, 76.2% and 74.0%. RT-MCE had higher specificity than DE-MRI (76.2%vs. 85.7%,P<0.05). The correlation between RT-MCE and DE-MRI was good.Conclusion RT-MCE and DE-MRI all have higher clinical value, and RT-MCE has higher specificity.
