Biggest things are cost and detail. An MRI shows incremental cross sections of the body part in greater detail.

Hi Pete;
MRI is a static exam with excellent imaging qualities. The cost is about 900-1,000. A diagnsotic ultrasound sound is about 200-325 per test and it is dynamic as compared to the static MRI. You can move the foot with the Diagnostic ultrasound and image as you look. It is site specific. You focus on the area that hurts and look at it. I think that the same imformation is obtained with a DX Ultrasound a a fraction of the cost and is done in office as opposed to setting up an appointment to have it done at an outside facility.

Dr Cozzarelli,

In the case of a plantar fibroma.......
Between Ultrasound and MRI....which one do you think might give a better indication of:

1. the degree of nerve entanglement with the fibroma?
2. the degree of attachment between the plantar facia and the fibroma?

Thank you!
