Apparently you are not supposed to eat carbohydrates 48 hours before a PET scan. Who knew? Well okay, I sorta knew as I used to read about some people’s pre-PET regimens on the Colon Club forum, but as nobody here had ever said anything other than I shouldn’t eat six hours before the scan I didn’t think it mattered that much.
Turns out that it is rather important as too much carb-sugar can skew the scan results, often ending up with false positives. Likewise doing any strenuous exercise 48 hours before a scan. I actually knew about the latter but can’t actually see the connection in the same way as the sugar connection – Sledpress, can you shed any light on this?
It also turned out that, coming home after two days of – let’s be honest – some rather intense tapearing in Málaga, I felt like I needed to detox a bit. So yesterday I eschewed carbs and went for nice light veggie and protein meals, which means that just by chance I am doing the 48-hour thing. But I wonder why I have never been told about this at the hospital here. Ah well, by this time mañana I will know if I am okay for another six months or if……

I’ll be thinking of you, too.
(And I’m curious about the reasons for the low carb before the scan, too. No idea.)

Well, if the scan detects metabolic activity — I see here on Wikipedia that the “glowing” molecule for cancer metastasis detection is a glucose analogue — then metabolism of glycogen, or muscle sugar, which is how the muscle cells store glucose for immediate uptake, might throw off the results.
I always wake up in the middle of the night which is about when you’ll be going in, and I’ll be transmitting thought waves…
