How is magnetic resonance imaging (MRI) used to diagnose deep vein thrombosis (DVT)?

ANSWER

During an MRI, you lie still on a sliding table while radio waves and a strong magnetic field make detailed pictures of the inside of your body on a computer. (You'll hear loud tapping or knocking sounds during the test.) You might need to get a shot to make your blood vessels stand out more.

This can find DVT in your pelvis and thigh -- and your doctor can look at both legs at once.
