If you search, the answer to this: How is MRI of the anus performed? The anorectal zone of rectum and anus is a part of the gastrointestinal tract that is engaged in transit of wastes. Due to complex anatomy and vulnerable situations, disease diagnosis in this area is most commonly dependent upon application of advanced imaging modalities. Human equivalent Magnetic Resonance Imaging or MRI is just one of those very helpful test procedures that provides accurate anatomical and pathological information without using radiation.
Why an MRI Scan of the Anus May Be Needed?
It is very easy to use when scanning anal canal complex structures, sphincter muscles, tissues in the surroundings, and disease state.
Evaluation of Perianal Fistulas: This pathologic tunneling between anal canal and covering skin is ordinarily complex and cannot be appropriately evaluated by history and physical examination.
Diagnosis and Staging of Anal Cancer: MRI plays an important role in the initial diagnosis and staging of anal cancer. It can determine the size and extent of the tumor and involvement with adjacent tissues.
Inflammatory Bowel Disease (IBD) Complications: Perianal complications in the form of abscesses and fistulas are identified in patients with a history of Crohn’s disease. MRI can give an estimate of the severity and extent of complications for both medical and surgical needs.
Assessment of Sphincter Damage: Anal sphincter muscle damage during operation or delivery results in fecal incontinence. MRI assesses the integrity and extent of the sphincter defect, visualizes them and guides reconstructive surgical planning.

The scan would take 30-60 minutes depending on how complicated a scan and set of numbers needs to be completed.
Conclusion
MRI of the anus is a safe, non-surgical, and highly effective imaging modality that gives advanced information regarding the anal canal, sphincter muscle, and the surrounding tissue. What does MRI of the anus involve? It is required for the diagnosis of complex diseases such as fistulas, cancer, and injury to the sphincter, enabling appropriate treatment planning and follow-up treatment.
