[Abstract] 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 fistula, perianal abscess, hemorrhoids, anal fissure, 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.
[Keywords] Anal canal；Anus diseases；Magnetic resonance imaging
