  • An x-ray, ultrasound, CT, or MRI may show the infection and how deep it is. You may be given contrast liquid to help your foot show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can cause serious injury.

You may need surgery to remove infected or dead tissue. You may need an amputation. A diabetic foot ulcer can be life-threatening.
