MRI scans of the face and neck with contrast are generally safe, non-invasive tests that do not use ionizing radiation. However, the contrast material may cause side effects such as nausea, vomiting, or allergic reactions in some patients. Patients should inform their physician of any medical conditions, allergies, or medications they are taking before the test. Additionally, it’s important to follow all instructions provided by the medical facility for test preparation, such as avoiding metal objects and fasting before the test.
