The Datscan is actually meant to rule out Parkinsonism, not exactly to diagnose. However, it is still considered relatively new technology and since my DatScan showed nothing but a sort of fog in a skull, I was not overly impressed. I trust my neurologist and his recommendations. I’ve also been diagnosed by 3 other opinions and they all agree, which adds to my trust in my neurologist. A good neurologist doesn’t usually need the DatScan, especially if he’s been in practice for awhile, and since technology can fail just as often, if not more, I would go with your doctor and allow him to determine the diagnosis. Based on my DatScan, vague as it was, I was diagnosed with PD. That’s a pretty sketchy diagnosis based on vague evidence if looking at the DatScan film. And when my diagnosis was changed to MSA it had to be done without a scan.

I had a DAT. Scan as soon as l was diagnosed .My neurologist at the time said that it was the only test that could be relied upon to give a reliable diagnosis. I wish l could have kept that neurologist . I’ve had three others since and haven’t trusted any of them . I don’t have one at all now as mine retired last year and hasn’t been replaced as yet so we are just muddling on. Fortunately we have a very good Parkinson’s nurse

My husband's doctor sait it was great for a diagnosis and can be repeated in a few years to see the progression.

Neurologists with the MDS (Movement Disorder Specialist) certification have 2 years of additional training working exclusively with PwP's (People with Parkinson). But unfortunately, there are few yet certified.

If you find a Certified MDS you're lucky.

I need to ask my doctor about it.
