I've had a Lumbar Spine MRI a couple of years ago for my back pain and was given a diagnosis of DDD, Osteoarthritis, Spinal Stenosis & 2 bulging discs. The majority of my pain is felt in my SI joint area. I know my spine conditions can be the reason I have so much pain in my SI joint area, but...having said that, I need another MRI prior to seeing a back surgeon for a consultation. Can I request for a certain type of MRI? i.e would a Lumbar/Sacral MRI be appropriate? I'm concerned I may have Arthritis in the SI joint or SI dysfunction. Any suggestions or advice would be greatly appreciated.
