摘要(Abstract)：

目的:分析3.0T磁共振多序列成像在肛周脓肿和肛瘘诊断分型中的应用。方法:随机选取疑似肛周脓肿或者肛瘘患者237例,首先利用3.0T磁共振多序列成像,手术后所有患者的手术切出标本实施病理检查明确肛周脓肿或肛瘘;分析3.0T磁共振多序列成像检查对肛周脓肿患者分期、分型和肛瘘患者分型诊断的准确性,对比患者3.0T磁共振多序列成像诊断与病理检查Ⅰ期对两种疾病总根治率。结果:161例肛周脓肿及76例肛瘘患者均通过3.0T磁共振多序列成像检出,与病理结果一致;诊断肛周脓肿分期的准确率为98.76%(159/161)、分型准确率为98.76%(159/161),与病理结果比较,差异无统计学意义(P>0.05);根据3.0T磁共振多序列成像检测结果治疗患者总有效率(92.82%)与病理检查Ⅰ期患者的总有效率(99.16%)比较差异无统计学意义(P>0.05);肛周脓肿分级与Van Assche评分呈正相关性。结论:3.0T磁共振多序列成像检查可作为肛周脓肿及肛瘘诊断分型的重要方法。
Objective:To observe the application of 3.0 T multi-sequence MRI in the diagnosis and classification of perianal abscess and anal fistula.Methods:237 cases with perianal abscess or anal fistula were randomly selected.Firstly,3.0 T multi-sequence MRI was used to identify perianal abscess or anal fistula by pathological examination.The diagnostic accuracy of 3.0 T multi-sequence MRI in staging,classification and classification of patients with perianal abscess were analyzed.The overall curative rates of patients diagnosed with 3.0 T multi-sequence MRI and pathological examination of stage I for both diseases were compared.Results:161 cases with perianal abscess and 76 cases with anal fistula were detected by 3.0 T multi-sequence MRI.The results were completely conformity with the pathological examination.The accuracy of staging and typing of perianal abscess was 98.76%(159/161) and 98.76%(159/161),and there was no significant difference compared with pathological examination(P>0.05).According to the results of 3.0 T MRI multi-sequence imaging,there was no significant difference between the total curative rate(92.82%) and pathological examination(99.16%),P>0.05.The classification of perianal abscess was significantly correlated with Van Assche scores.Conclusion:3.0 T multi-sequence MRI can be used as an important method for the diagnosis and classification of perianal abscess and anal fistula.
