Objective: To investigate the diagnostic value of flash dual-source CT(DSCT)coronary imaging combined with myocardial perfusion imaging in acute myocardial infarction model of pigs. Methods: A total of 5 acute myocardial infarction models of pigs were cultured by means of gelatin sponge embolization, which were scanned by DSCT and "one-stop" generated coronary imaging and myocardial perfusion imaging and were compared with coronary angiography and pathology staining. Results: Compared with pathology staining, the results of myocardial perfusion imaging are as follows: the sensitivity was 93%, the specificity was 91%, the negative predictive value was 96%, the positive predictive value was 84%, and the Kappa value was 0.82; compared with coronary angiography, the results of coronary imaging are as follows: the sensitivity was 93%, the specificity was 81%, the negative predictive value was 95%, the positive predictive value was 75%, and the Kappa value was 0.71. Conclusion: DSCT coronary imaging combined with myocardial perfusion imaging is in a good consistency with coronary angiography and pathology staining, which can be used for the diagnosis of acute myocardial infarction model of pigs.
