    It's more accurate than an ultrasound, but there's a slight chance it will cause more blood clots.

    Magnetic resonance imaging (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 show up better.

    This can find DVT in your pelvis and thigh. And your doctor can look at both legs at once. MRI is much more expensive than other tests, though.
