Can you get a good MRI with cast on?

In most cases, an MRI scan can be performed with a cast on, as long as the cast does not contain metal components. Certain metallic components can distort MRI images and interfere with the accuracy of the scan. If the cast does contain metal, the doctor may recommend removing the cast temporarily for the MRI scan and reapplying it afterward.

Some MRI-safe cast materials include:

- Cast materials made of fiberglass, plastic, or fabric.

- Thermoplastic materials that can be reshaped by heat, such as Polypropylene or Polyethylene.

- Plaster casts that do not contain metal components.

Certain types of metal-containing casts or splints may need to be removed before the MRI, to ensure that the scan produces clear and accurate images. These include casts made of:

- Metal screws, bolts, or pins.

- Cast materials containing metal wires, rods, or plates.

- Metal alloy frames or materials.

If you have a metal cast, the radiologist or healthcare professional will assess it to determine if it's safe to undergo the MRI with the cast on. In cases where the cast must be removed, they may provide you with temporary immobilization measures to protect the injured area during the MRI procedure.

It is important to communicate with your healthcare team and inform them about the materials used in your cast or splint before scheduling an MRI scan. They can provide you with specific guidance on whether the MRI can be performed safely with your cast in place.
