When i had mine at addenbrokes.
the syringe was in a lead vase, lifted out by tongs, the nurse took a couple of measurements i presume too check the radio activity of the isotope, the syringe itself was covered in a lead jacket, you couldn't see any of the dye and after she injected it she also added some water solution.
And that was that for 4 or 5 hours i was free too wander the hospitals shopping and food complex which is large and impressive like it would put any town too shame, until the afternoon, the scan it self was totally different and kinder in my opinion too a M.r.i, a little russian doctor adjusted a panel closely to slowly rotate around my head, i laid back for 20-30 mins and almost fell asleep
He woke me almost, ''that's it all done'' he said, i asked him what happens next, he said ''your results will be with your neurologist by tmrw afternoon, you should make a emergency appointment with your neuro'' he said.
It was a subtle hint from him in a way, my results were with the neuro the next day as he said, and with my gp within a week, i have a copy i later got of the letter tween addenbrokes the neuro and the gp, but No one fought too tell me until 6 weeks later.the neuro had told the gp, but the gp hadn't told me and when i turned up for appointment with the neuro he thought i'd already been told the results, a c*ck up.
the results anyway showed i have reduced uptake on both spheres(sides) of my brain, hence PD diagnosis.
