This exam is done feet first and your head will not go into the scanner. You will be given hearing protection as the MRI machine makes a series of loud noises.
What injection is given during MRI?
Gadolinium contrast media (sometimes called a MRI contrast media, agents or ‘dyes’) are chemical substances used in magnetic resonance imaging (MRI) scans. When injected into the body, gadolinium contrast medium enhances and improves the quality of the MRI images (or pictures).
How long does an MRI of the foot and ankle take?
The length of an ankle MRI is typically 30-35 minutes and will require you to hold very still. MRI scans are sensitive to motion and any motion may obscure information the Radiologist uses to make a formal report.
What does an MRI show on a foot?
MRI Scans. During an MRI scan, magnetic fields and radio waves are used to create images of ligaments, tendons, and cartilage in the foot and ankle. Your doctor may recommend an MRI scan to help pinpoint the cause of your symptoms, particularly if they don’t improve after four to six weeks.
Can you wear pants during an MRI?
Please wear comfortable clothing. Cotton, polyester, and wool are best. Don’t worry about the snaps or zippers on pants, as that metal can be allowed into the scanning facility. If you have questions about these procedures, please feel free to contact the study coordinator.

What kind of MRI do you need for joint pain?
Arthrography is an MRI technique used to image joints if a standard MRI does not provide enough detail. 10 Arthrography requires an intra-articular injection of GBCA into the joint space. The injection itself can cause localized pressure and pain.
What kind of MRI do I need for my foot?
Magnetic resonance imaging, otherwise known as MRI, uses a combination of magnetic fields and radio waves to take images of the internal structures of your body. Your doctor, with the help of a radiologist, can then examine these images to determine whether there is anything wrong with your foot…
Can a MRI be done without a dye injection?
If you are getting an MRI that does not require a contrast dye injection, you can skip steps 2-5. Consider yourself lucky. Also, I hate you.

How does a doctor inject contrast into a joint?
Injects contrast dye or air with a long, thin needle — your doctor will use fluoroscopy or ultrasound to guide the needle to the area around your joint. You may be asked to move the joint around so the dye spreads out. Takes images of your joint in different positions with either X-ray, fluoroscopy, MRI, or CT.
What happens when you get an MRI contrast injection?
Most people feel nothing after receiving an injection of contrast, Dr. Taouli says. Only a very small number of people will have adverse effects. Of those, a skin rash, hives, and pain at the injection site are more common. Dr. Biondo-Savin says he’s also had patients say they feel warm or dizzy, “but that’s very rare,” he adds.
