MRI Foot Without Contrast

Specimen Required

NONE

Fasting Required

Purpose of the Test

An MRI of the foot without contrast may be ordered to investigate the cause of unexplained foot pain, swelling, or deformity, to evaluate a foot injury, or to monitor the progression of a foot condition or disease. It can also help diagnose a range of foot and ankle problems, including fractures, sprains, arthritis, tendonitis, plantar fasciitis, and neuromas.

When this test is required

An MRI of the foot without contrast may be requested by a doctor or healthcare provider when a person has symptoms of a foot or ankle problem, including pain, swelling, or deformity. It may also be requested to monitor the progression of a known foot condition or disease.

What the Test Detects

During an MRI of the foot without contrast, the person lies still on a table that slides into the MRI machine. The machine uses a powerful magnet and radio waves to create detailed images of the foot’s bones, joints, soft tissues, and blood vessels. These images can help the doctor or healthcare provider diagnose foot problems such as fractures, ligament or tendon injuries, arthritis, and tumors.

Preparation for the Test

In general, no special preparation is required before an MRI of the foot without contrast. However, the person will be asked to remove any metal objects such as jewelry or watches before the test, as they can interfere with the MRI machine. The person may also need to wear a hospital gown during the test. The MRI machine is a narrow tube, and some people may feel claustrophobic during the test. If this is the case, the healthcare provider may offer a mild sedative to help the person relax.

Sample Requirements

No sample is required for an MRI of the foot without contrast.

Additional Notes

An MRI of the foot without contrast is generally safe and painless. However, because it uses powerful magnets and radio waves, it is not recommended for people with certain medical conditions, such as pacemakers or metallic implants. The person undergoing the MRI should inform the healthcare provider if they have any medical conditions or implanted devices before the test. The test may take 30-60 minutes to complete, and the person should remain still during the test to obtain the clearest images possible.
