Before the MRI ankle test, patients should remove any metallic objects such as jewelry, piercings, watches, or eyeglasses, as they can interfere with the magnetic field. Patients should also inform the healthcare provider if they have any metal implants or pacemakers, as they may be contraindicated for the MRI exam. The patient may be asked to wear a gown and lie on a table that slides into the MRI machine. In addition, patients receiving an MRI ankle with contrast may be required to fast for several hours before the exam.
