MRA Leg With Contrast

Specimen Required

NONE

Fasting Required

Purpose of the Test

A doctor may recommend an MRA Leg With Contrast to evaluate blood flow and detect blockages or other abnormalities in the blood vessels of the leg. The test can help diagnose conditions such as peripheral artery disease, blood clots, or aneurysms.

When this test is required

The test may be requested when a patient has symptoms such as leg pain, cramping, or numbness that may be due to poor blood flow, or if the doctor suspects the presence of an aneurysm or blood clot.

What the Test Detects

An MRA Leg With Contrast generates detailed images of the blood vessels in the leg using a magnetic field and contrast dye. The contrast dye is injected into a vein in the arm or hand to make the blood vessels more visible in the images.

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, stopping certain medications, or informing the doctor of any allergies to contrast dye.

Sample Requirements

No sample is required for this test.

Additional Notes

MRA Leg With Contrast is a safe and noninvasive test, but it does involve exposure to a strong magnetic field and the use of contrast dye, which may cause allergic reactions in some people. Patients with certain types of metal implants may not be eligible for the test. Additionally, the test may not be suitable for patients who are pregnant or have kidney problems.
