Scan Types / MRI Perianal Fistula Scan
MRI Perianal Fistula Scan
An MRI perianal fistula scan provides high-definition imaging of the anal canal, perineum, ischioanal spaces, and surrounding structures. It is the gold standard for diagnosing and mapping perianal fistulas, abscesses, and fistula tracts, especially in patients with Crohn’s disease or recurrent infections.
What is an MRI perianal fistula scan?
This scan uses dedicated pelvic MRI sequences to visualise:
- The internal and external anal sphincters
- Fistula tracts (intersphincteric, transsphincteric, suprasphincteric, extrasphincteric)
- Abscesses or collections
- Relationship to sphincters and rectum
- Post-surgical or chronic changes
MRI is the most accurate imaging modality for classifying fistulas and aiding surgical planning.
Why consider a private MRI for perianal fistulas?
Perianal fistulas can be painful, recurrent, and complex. MRI helps in precise diagnosis, classification, and preoperative assessment — critical for avoiding recurrence or sphincter damage.
Advantages of private MRI:
- Fast access and reporting
- Detailed surgical roadmap for colorectal surgeons
- No radiation exposure
- Suitable for patients with Crohn’s disease
Symptoms that may warrant a perianal MRI
This scan may be recommended if you have:
- Persistent pain or swelling around the anus
- Recurrent perianal abscesses
- Foul-smelling or bloody discharge
- Previous surgery for fistula or abscess
- Diagnosed Crohn’s disease with perianal involvement
- Difficulty with wound healing post-surgery
What can a perianal MRI detect?
This scan can help identify:
- Internal and external fistula openings
- Complex or branching tracts
- Perianal abscesses
- Inflammatory changes in Crohn’s disease
- Involvement of the anal sphincter
- Recurrence after prior surgery
- Co-existing rectal or pelvic pathologies
Preparing for your perianal MRI
What to expect:
- Fasting is usually not required
- You may be asked to empty your bladder beforehand
- No rectal contrast is required in most cases
- Wear metal-free clothing and remove accessories
