Overview
Fistulography is used to diagnose anal fistula in the past but is replaced by MRI nowadays. This is used to find out the anatomy of fistulas.
X Ray
- Fistulography is used to diagnose anal fistula in the past.
- Fistulography is painful and invasive procedure so it is replaced by MRI nowadays.
- This is used to find out the anatomy of fistulas.
Procedure:
- A fine cannula is catheterized through the external opening, a water-soluble contrast agent is injected to find out the fistulous track and after that X-ray is taken.
Drawbacks of fistulography:[1][2]
- It is very difficult to assess fistula with multiple tracks due to the filling defect with contrast material.
- Fistulography is not used to visualize the anal sphincter.
