What Are the Risks of Chest MRI?

The magnetic fields and radio waves used during chest MRI pose no risk.

Serious reactions to the contrast dye used for some MRI tests are very rare. However, side effects are possible and include the following:

  • Headache.
  • Nausea (feeling sick to your stomach).
  • Dizziness.
  • Changes in taste.
  • Allergic reactions, such as hives and itchy eyes. If you have an allergic reaction, your doctor can give you medicine to relieve your symptoms.

Rarely, contrast dye is harmful to people who have moderate to severe kidney disease.
