@redbeets I leave it to my doctors to determine the best type of imaging for diagnosing my health issues, so I cannot say which is best. Depending upon issue and location, I have had x-ray studies, MRI, and CT scans with and without contrast. With injections to a specific area, my docs have variously used ultrasound or x-ray guidance depending upon location.

I figure they went to school for up to 12 years to learn everything, my few hours of research doesn't even begin to compare.
