MRI Anal Fistua (FIA) With Contrast

Specimen Required

NONE

Fasting Required

Purpose of the Test

A doctor may recommend an MRI Anal Fistula (FIA) with Contrast if a patient is experiencing pain, discomfort, or discharge in the anal region, as this could indicate the presence of an anal fistula. The test can help to identify the presence and extent of the fistula and guide appropriate treatment.

When this test is required

The test may be requested when a patient is experiencing symptoms such as pain, discomfort, or discharge in the anal region, which could indicate the presence of an anal fistula. It may also be ordered when previous imaging tests have not provided enough information or when a doctor suspects the presence of a fistula.

What the Test Detects

An MRI Anal Fistula (FIA) with Contrast generates detailed images of the anal region using a strong magnetic field and radio waves. The contrast agent is injected into a vein to help improve the visibility of the blood vessels and soft tissues in the area.

Preparation for the Test

Patients may need to follow specific instructions from their doctor regarding preparation for the test, such as avoiding food or drink for a certain period before the test or taking laxatives to cleanse the bowel.

Sample Requirements

No sample is required for this test.

Additional Notes

MRI Anal Fistula (FIA) with Contrast is a safe and noninvasive test, but it does involve exposure to a strong magnetic field, so patients with certain types of metal implants may not be eligible for the test. Additionally, the contrast agent used in the test can cause allergic reactions in some people, so patients should inform their doctor if they have a history of allergies or other medical conditions. Patients should also inform their doctor if they are pregnant or breastfeeding before undergoing the test.
