This morning started out at the medical group so I could get my PET CT and CaT scans done. The CaT scan looks at, basically, the torso. (The MRI will check out my head.) The PET CT scan works a little differently.
The PET CT scan traces the glucose in my system because the glucose sticks to areas of cellular activity. Although they expect to find it in places like my liver, if it shows up in unexpected places that could mean a cancer site.
When I first arrived they put me in a small “relaxation” room and stuck an IV in my arm so they could use it later. The first thing they put in the IV was a radioactive isotope. I was told they would leave me alone for about 45 minutes because that was the amount of time it took for it to dissipate sufficiently for me to be safe to be around. No, I didn’t glow.
I was given a liter of “contrast,” which is basically something added to water. I was told to drink it very slowly over the next 45 minutes but to leave a half glass. Although I brought a book to read during my relaxation, they really didn’t want me reading. Apparently, any activity shows up in your muscles when they do the scan. So I spaced out and sipped my “contrast.”
They eventually showed up to take me in to have the scans. Since I’ve already been diagnosed with melanoma they were doing a “top of head to toes” scan rather than the normal torso scan. I don’t know which part was which scan. The machine has a sliding table you lay on and it moves you in and out of a big tube. First they gave me the glucose through the IV while I was on the moving table. A kind of a torso scan only lasted a few minutes. Then they did a lower body scan that took about 12 minutes. At that point I had to flip around so they could do the upper body for about 15 minutes. Then I was done. In and out in just over a total of 2 hours.
