Read our detailed review of the MRI foot scan. Learn about the procedure, preparation, and how it helps accurately diagnose foot pain and injuries.
Overview
If you have sharp pain in the heel, swelling of the midfoot or ache in the toes at the close of the day, you could be greatly constrained in your independence. When conservative treatment like rest, icing, and physical therapy efforts are not relieving your foot pain, your foot doctor will have to take a look under the skin to determine what is happening. There the Magnetic Resonance Imaging (MRI) of the foot is of great assistance. This sophisticated technology gives your healthcare team an indepth, 3-D representation of your lower limb to ensure that you receive a treatment plan that is tailored to 100% certainty.
How is MRI Foot Done?
This is frequently likened to a conventional orthodontic radiograph and patients wonder. An MRI overcomes the diagnostic gap by using a powerful magnetic field and radio waves to deliver a complete image, but it does not emit any of the harmful ionizing radiation that is produced by an xray or computed tomography (CT) scan.
This innovative combination acts in collaboration with the water molecules in the body to produce a high resolution 3 planar views of your foot. Its ability to reveal the intricate web of muscles, ligaments, tendons and cartilage that provide balance and mobility in an unprecedented tissue contrast none of any other scans can compare.
What is the MRI Foot used to look for?
This new imaging technology is available to foot specialists to diagnose numerous complex issues. It is commonly used in studies of:
Achilles and Plantar Issues: To evaluate extreme micro-tears in the plantar fascia or the important point of attachment of the Achilles tendon to the heel.
Inflammatory arthritis of the synovial joints: To see the aggressive arthritis such as rheumatoid flareups and gout arthritis that damages the lining of the joint. This test helps in locating pinched nerves or a benign fluid-filled sac (ganglion cyst) precisely to determine the location of pressure that can be immense.
Occult Bone Trauma: For detection of deep bone marrow edema (bruising) or microcracks (stress fractures) which are seen in athletes, runners and dancers.
How is MRI Foot Done?
Clothing Change: You will change into a comfortable gown with no zippers, snaps or buttons to interrupt the magnetic field.
Getting Settled: You will be sitting on a moving examination chair. A small lightweight receiver, called a "coil," will be placed around your foot which functions as an antenna to significantly improve the clarity of the image.
Relaxation and a totally still body in the toes position is required during the Scanning Phase of the bed. There will be acoustic knocking and buzzing noises, the magnet is working. Ear defense or music provided to keep comfortable.
Time frame: It takes 30-45 minutes to screen.
Frequently asked questions (FAQ)
Should I take off my toe rings or ankle bracelets?
Yes. Any type of metallic jewelry must be removed before entering the scanning suite for safety reasons.
Is the machine able to diagnose gout?
Yes, it is very helpful in illustrating the precise joint inflammation and tissue alterations of acute attacks of gout.
If I have very bad bunions or hammertoes is that okay?
Absolutely. The scanner and foot coil easily fit any foot shape and deformity without causing any additional pain.
Will I feel any heat or physical sensation during the scan?
No, the procedure is completely painless although a very mild harmless warming sensation may be felt in the area being scanned.
May I use my regular shoes at the clinic?
Any kind of shoes that you like will be suited for this appointment and you will need to take your shoes off before you can have the test.
Is anybody going to drive me home?
No. Because you don't get any sedation, you can drive yourself right after the appointment.
