摘　　要：目的分析MR扩散张量成像(DTI)对急性心肌梗死(AMI)后室性心律失常的评估价值。方法采取病例对照研究方法,纳入2018年10月-2022年10月期间在广西崇左市人民医院采用MR DTI进行检查的65例AMI后室性心律失常患者的临床资料作为观察组,另纳入同期该院收治的65例AMI后未出现室性心律失常的患者的临床资料作为对照组,收集所有患者MR DTI影像数据,分析MR DTI对AMI后室性心律失常的评估价值。结果观察组梗死区及边界区的FA值低于对照组,MD值高于对照组,差异有统计学意义(P<0.05);绘制受试者工作特征曲线(ROC)曲线图,结果显示,MR DTI参数对AMI后室性心律失常的评估AUC均>0.7,评估效能较好。结论MR DTI对AMI后室性心律失常具有较好的评估价值。Objective To analyze the value of MR diffusion tensor imaging(DTI)in evaluating ventricular arrhythmia after acute myocardial infarction(AMI).Methods A case-control study was adopted,and the clinical data of 65 patients with ventricular arrhythmia after AMI who were examined by MR DTI in the People's Hospital of Chongzuo,Guangxi from October 2018 to October 2022 were included as the observation group.In addition,the clinical data of 65 patients without ventricular arrhythmia after AMI admitted to the hospital in the same period were included as the control group.MR DTI imaging data of all patients were collected to analyze the value of MR DTI in evaluating ventricular arrhythmia after AMI.Results The FA value of infarct area and boundary area in the observation group was lower than that in the control group,and the MD value was higher than that in the control group,and the difference was statistically significant(P<0.05).The receiver operating characteristic curve(ROC)curve was drawn.The results showed that the AUC of MR DTI parameters for the evaluation of ventricular arrhythmias after AMI was>0.7,and the evaluation efficiency was good.Conclusion MR DTI has a good value in evaluating ventricular arrhythmia after AMI.
