摘　　要：目的:研究磁共振成像(MRI)扫描检查对肛周脓肿(PA)与肛瘘(AF)的诊断价值。方法:回顾性分析2016-2020年我科收治的98例PA和AF患者临床资料,所有受检者均接受术前MRI扫描检查并给出诊断结果,以术后病理结果作为金标准计算MRI诊断PA的灵敏度、特异度,并绘制其操作特征曲线(ROC)分析MRI诊断PA的价值。结果:98例受检者经术后病理证实PA 68例,AF 89例;术前MRI检出PA患者60例,检出病灶60个;术前MRI检出AF患者89例,瘘管89条,内口89个,经对比计算出术前MRI诊断PA的灵敏度为88.24%(60/68),特异度为96.67%(29/30);ROC曲线显示术前MRI诊断PA的ROC曲线下面积(AUC)为0.883,95%CI为0.877~0.895。结论:术前MRI对PA、AF具有较高诊断效能,可为临床提供术前诊断依据。Objective To investigate the value of MRI in diagnosing perianal abscess(PA)and anal fistula(AF).Methods Retrospectively analysed the clinical data of 98cases of PA and AF treated in author’s apartment(2016-2020):all the patients received preoperative MRI screen inspection and were given diagnostic results,by using postoperative pathological results as golden-standard MRI’s sensitivity and specificity in diagnosing PA were estimated;then,via ROC the value of MRI for diagnosing PA was analysed.Results In the 98 cases,68 were confirmed by pathological exam.after surgery as PA,89 as AF,meanwhile,preoperative MRI found 60 cases with PA and their lesions of 60,also found 89 cases with AF,and their 89 fistula tract,as well as 89internal opening.Thus in diagnosing PA preoperative MRI’s sensitivity and specificity were respectively 88.24%(60/68)and 96.67%(29/30);ROC shown AUC of the MRI in diagnosing PA was 0.883,95%CI was 0.877-0.895.Conclusion Preoperative MRI has higher efficacy in diagnosing PA and AF,can provide basis for preoperatively clinical diagnosis.
