MRI Fistulogram (Plain) in Bihar
Non-contrast pelvic MRI for fistula evaluation at JP Diagnostic. Our 1.5T/3T MRI with specialized T2-weighted sequences visualizes perianal and pelvic fistula tracts, abscesses, and sphincter involvement without radiation — trusted by general surgeons, colorectal surgeons, and gastroenterologists across Patna, Gaya & Muzaffarpur.
What is an MRI Fistulogram (Plain)?
A non-contrast MRI examination focused on mapping fistulous tracts — primarily perianal and perirectal — using heavily T2-weighted and STIR sequences. Fluid and pus within the tract appear bright, allowing detailed visualization of the tract path, internal opening, abscess cavities, and relationship to anal sphincters without injecting contrast.
Fistula Tract Mapping
Clearly delineates the course of simple and complex fistula tracts, identifies internal openings, and classifies according to Parks’ criteria.
Abscess Detection
Identifies associated abscesses, horseshoe extensions, and secondary tracts that may be missed on clinical examination.
Sphincter Assessment
Evaluates the relationship of the fistula to the internal and external anal sphincters, critical for surgical planning and preserving continence.

MRI Fistulogram is the gold standard for complex fistulas, supralevator extensions, and pre-operative sphincter assessment — without radiation.
The Procedure
What to expect during your MRI Fistulogram (Plain) at JP Diagnostic. Total time: 25 to 40 minutes.
Check-in & Screening
Present your surgeon’s referral. Our front desk verifies your identity and previous surgical reports. Remove all metal objects and change into a hospital gown. Complete the MRI safety questionnaire.
Positioning
Lie comfortably on your back or in a prone position depending on protocol. A pelvic phased-array coil is positioned over the lower pelvis. Padding ensures comfort and minimizes motion.
Scanning
The table slides into the MRI tunnel. You must remain completely still. The scan uses heavily T2-weighted sequences where fluid in the fistula tract appears bright white. No IV contrast is injected for a plain study. Earplugs are provided.
Post-Scan & Results
The table slides out. Dress and collect your belongings. Our radiologist performs a preliminary review before you leave. Your detailed report with tract mapping is ready within 24 hours.
How to Prepare
Pelvic MRI requires specific preparation to ensure optimal image quality and comfort.
✅ Do’s
- Wear loose, comfortable clothing without metal zippers
- Empty your bladder before the scan
- Inform staff of any prior anal surgery or seton placement
- Bring prior surgical reports and discharge summaries
- Inform if you have a pacemaker or pelvic implants
- Arrive 15 minutes before appointment
- Inform if you have claustrophobia
❌ Don’ts
- Do not insert any rectal suppositories or enemas on scan day unless instructed
- Avoid wearing belts or clothing with metal buckles
- Do not bring electronic devices into the scan room
- Avoid scheduling during active heavy rectal bleeding if possible
- Do not wear jewelry or piercings below the waist
- Avoid excessive movement during the scan
Special Cases
| Condition | Required Preparation |
|---|---|
| Claustrophobia | Request wide-bore MRI or mild sedation (requires fasting + escort) |
| Post-Surgical Seton | Inform staff; most setons are MRI-safe but must be documented |
| Pregnancy | Inform technician; usually avoided in 1st trimester unless urgent |
| Severe Anal Pain | Inform staff; we provide positioning cushions |
| Contrast Study (if upgraded) | Blood creatinine test required to check kidney function |
Duration & Report Timing
We understand the urgency of surgical planning and prioritize rapid reporting.
| Scan Type | Duration |

| MRI Fistulogram with Contrast | 35 – 50 minutes |
| MRI Pelvis + Fistulogram | 40 – 55 minutes |
| MRI Fistulogram with Sedation | 1 – 1.5 hours |
Safety & Risks
MRI Fistulogram is extremely safe, with no radiation and no contrast-related risks for the plain study.

💡 Safety First: JP Diagnostic uses advanced MRI screening protocols. Our radiologists review every case individually before proceeding, especially for patients with prior pelvic surgery, setons, or implants.
Frequently Asked Questions
Everything you need to know about MRI Fistulogram (Plain) in Bihar.
Plain MRI fistulography uses heavily T2-weighted and STIR sequences. Fluid and inflammatory material within the fistula tract naturally appear very bright (white) on these sequences, allowing excellent visualization of the tract path, internal opening, and abscesses without injecting any contrast.
Yes. Conventional fistulograms inject contrast through the external opening and take X-rays, but they often miss complex tracts, secondary branches, and abscesses. MRI provides a 3D view of the entire fistula, sphincter relationship, and pelvic extensions — without radiation.
Plain MRI is excellent for most simple and complex fistulas, especially when there is fluid in the tract. For very fibrotic or healed tracts with minimal fluid, contrast-enhanced MRI may provide additional information. Your surgeon will advise if contrast is needed.
MRI itself is completely painless and non-invasive. There are no needles or injections for a plain study. If you have significant anal pain, inform our staff — we provide soft padding and comfortable positioning to minimize pressure on the affected area.
Usually no extensive bowel prep is required for a plain MRI fistulogram. We may advise emptying your bladder and bowels before the scan for clearer images. If your doctor has requested specific preparation, follow their instructions.
MRI Fistulogram cost in Bihar ranges from ₹5,000 to ₹10,000 depending on the center and whether contrast is added. At JP Diagnostic, we offer competitive pricing with EMI and insurance cashless options. Call us for exact pricing.

Expert Opinions
When do leading surgeons recommend an MRI Fistulogram?
For any complex or recurrent perianal fistula, MRI is mandatory before surgery. It prevents unexpected findings in the operating room, reduces recurrence rates, and preserves sphincter function by mapping the exact tract relationship.
In Crohn’s disease with perianal involvement, MRI fistulogram is indispensable. It identifies hidden abscesses and tracks that clinical examination cannot reach, guiding both medical and surgical management.
Plain MRI fistulography using high-resolution T2 sequences provides excellent tract visualization without contrast. It is my preferred first-line imaging for pre-operative fistula assessment, especially in patients with renal concerns.
