When “contrast” is required

Some types of scans require the use of a contrast medium to provide a clear image. Also, your physician may request the use of a contrast medium. The MRI contrast agent is administered intravenously. If you are a diabetic or have limited kidney function, please alert us, as this may affect the use of MRI contrast.
