摘　　要：目的:探讨高分辨率磁共振成像(Magnetic Resonance Imaging,MRI)联合弥散加权成像(Diffusion Weighted Imaging,DWI)在肛瘘患者中的评估价值。方法:回顾性收集2020年1月至2023年10月于本院治疗的65例肛瘘患者的临床资料。所有患者术前均行高分辨率MRI、DWI检查。以手术结果为金标准,统计高分辨率MRI联合DWI评估Parks分型的结果,并分析其与手术结果的一致性及准确度。结果:手术结果显示,65例患者中括约肌间型32例,经括约肌型23例,括约肌上型6例,括约肌外型4例。高分辨率MRI评估分型结果与手术结果一致性较强(Kappa值=0.723,P<0.05);高分辨率MRI联合DWI评估分型结果与手术结果一致性强(Kappa值=0.879,P<0.05);高分辨率MRI检查准确度为81.54%(53/65)、高分辨率MRI联合DWI检查准确度为93.85%(61/65),差异有统计学意义(P<0.05)。结论:高分辨率MRI联合DWI具有较高的评估价值,可明确肛瘘分型,为临床手术治疗提供依据。Objective:To explore the evaluation value of high-resolution magnetic resonance imaging(MRI)combined with diffusion weighted imaging(DWI)in patients with anal fistula.Methods:Clinical data of 65 patients with anal fistula treated in our hospital from January 2020 to October 2023 were retrospectively collected.All patients underwent high-resolution MRI and DWI examination before surgery.Surgical results were used as the gold standard,the results of high-resolution MRI combined with DWI evaluation of Parks classification were statistically analyzed,and their consistency and accuracy with surgical results were analyzed.Results:The surgical results showed that among the 65 patients,there were 32 cases of inter sphincteric type,23 cases of trans sphincter type,6 cases of upper sphincter type,and 4 cases of external sphincter type.The consistency between the classification results of high-resolution MRI evaluation and surgical results is strong(Kappa value=0.723,P<0.05).The combination of high-resolution MRI and DWI showed strong consistency between the classification results and surgical outcomes(Kappa value=0.879,P<0.05).The accuracy of high-resolution MRI examination was 81.54%(53/65),and the accuracy of high-resolution MRI combined with DWI examination was 93.85%(61/65),with a statistically significant difference(P<0.05).Conclusion:The combination of high-resolution MRI and DWI has high evaluation value,which can clarify the classification of anal fistula and provide a basis for clinical surgical treatment.
