肛管是消化道的重要组成部分,具有复杂的解剖结构。近年来发生于肛管和肛周的疾病呈上升趋势,常见疾病包括肛瘘、肛周脓肿、痔、肛裂等,少见病包括肛管肿瘤、骶尾部藏毛窦及性疾病等,这些疾病严重影响患者的生活质量。MRI具有较高的软组织分辨率,能够全方位、多平面成像,作者着重探讨肛管和肛周疾病的MRI检查技术和表现,旨在提高对肛管和肛周疾病的诊断水平。
The anal canal is an important part of the gastrointestinal and has complex anatomic structure. Diseases occurring in the anal canal and perianal have increased in recent years, including anal ifstula, perianal abscess, hemorrhoids, anal ifssure, anal carcinoma, sacrococcygeal pilonidal sinus and so on, they can have serious effect in patients＇ quality of life. MRI has perfect soft-tissue resolution and comprehensive and multi-planar imaging. This article mainly talks about the performance of these diseases in MRI and the MRI technique in order to improve the level of diagnosis in anal canal and perianal diseases.
