I believe you said in other threads that your skin biopsy was done at Hopkins, so I'll assume you are referring to a clinic at Hopkins for the MRI. I don't know whether a 'technician' will know about the DRG Protocol. The radiologist that actually read my MRI was Avneesh Chhabra, MD. He specializes in MR neurography (even wrote a book with the same title). I don't know if you mention a name whether it would help get you this specialized test or not...but it can't hurt. I would ask your neurologist about it (if he is at JH), not the MRI clinic. My test was ordered through my neurologist.

I will add that my neurologist specifically asked them to look at the DRG due to my Sjogren's diagnosis. I have also asked a radiologist on this forum about this protocol. He said he had not heard of it specifically under that name, BUT that a strong enough magnet could definitely see the DRG.

I understand (I really do), the need for a 'cause', but treatment is the key. IF you can find something to alleviate your pain/suffering, then the cause is just a name. It took years and years for a diagnosis of Sjogren's for me. Even though I had known in my mind that there was ONE cause for all my secondary diagnosis, I had given up hope of ever finding out what it was. I was always more concerned with finding a means to control my symptoms. I think we have ALL considered diagnosis for ourselves at some point in our medical journey. Being your own advocate with your doctor is the best thing you can do for yourself. Stay on top of your testing and learn about your symptoms so that you can have productive discussions with your doctor.
