I presented my forms at the desk of nuclear medicine at 8 am. By 8:30, the technician was injecting 4 needles around my melanoma site, on my arm. I was wheeled to surgery , with results in hand, for a 10:30 survey. By 10:45 , I was under and I was released by 1 pm.
Tne majority of time, in nuclear medicine, was waiting for the dye to move through the lymph system.
I expect that this would vary, depending on the site.
