目的：分析磁共振T2WI压脂及T1WI压脂增强序列在肛痈及肛漏诊断中的价值。方法：41例肛痈及肛漏患者均行常规及Gd-DTPA增强磁共振检查，经手术证实，对以上各磁共振扫描序列组合对各种类型肛痈、肛漏及其内口的检出率进行统计分析。结果：肛痈32个，肛漏26个。对于肛痈、肛漏检出率，矢状位平扫及增强T1Wl压脂序列与手术结果比较差异均有统计学意义（P<0.05）。矢状位平扫及增强T1Wl压脂序列对肛漏、肛痈的检出略高于轴位T2WI+冠状位T2WI序列和轴位T2WI压脂+冠状位T2WI压脂序列，但差异无统计学意义（P>0.05）。结论：轴位联合冠状位T2WI压脂序列及T1WI压脂增强扫描序列可明显提高肛痈、肛漏临床诊断正确率，为手术方式的最佳选择提供科学信息。%Objective:To analyze the value of mri T2WI pressure grease and fat enhanced T1WI pressure sequence in diagnosis of anus carbuncle and anal leakage.Method:41 patients with anal carbuncle and anal leakage both conventional and Gd-DTPA enhanced magnetic resonance examination,confirmed by surgery,the combination of all mri scanning sequences of various types of anal abscess in mouth,anus leakage and its detection rate were analyzed. Result:Anal carbuncle was 32,anal leakage was 26.For abscess,anal leakage inspection rate,sagittal scan and enhanced T1Wl pressure grease series all had significant difference compared with surgical results(P<0.05).Plain and enhanced sagittal fat-suppressed sequences T1Wl for anal leakage,check out slightly higher than the shaft of the anus carbuncle T2WI and coronal T2WI sequences and shaft a T2WI pressure grease+coronary a T2WI fat sequence,there was no significant statistical significance(P>0.05).Conclusion:Shaft joint coronary bits fat T2WI pressure fat sequence and T1WI enhancement scan sequence can obviously improve the anus carbuncle,anal leakage clinical diagnostic accuracy, provide scientific information for the best choice of the surgical procedure.
