Can I get a Noncontrast MRI if I have GDD? A response to a sufferer, which is generalizable.

The is a short blog, a response to a question I often get:

these symptoms are almost certainly GDD. About 1/3- 1/2 of people with GDD who get noncontrast MRI will experience Flare from that - at this point the only way to find out if you are in that 1/3- 1/2 is to get a noncontrast MRI and see how you do. Since I don't think a syrinx is the problem and I am not sure finding one is the cause. I do not recommend a noncontrast MRI at this time. Generally how I approach these situations is: if it is likely to be GDD-related, then undergo 5 chelations (maybe 10) if the symptoms have not improved at all then look at other things. At that point a noncontrast MR would much less likely result in Flare, because there simply is less Gd in your body to cause Flare.

If the investigation/treatment carries a much greater risk of harm: such as ablation of electrical conduction foci in the heart or resection of bowel, then I would wait for at least 10 chelations (or more) before agreeing to undergo these procedures.
