I've been meaning to start special postings just for tubies, i.e., those of us who can not eat and need a feeding tube.
My wife just reminded me that prior to being on a feeding tube, I had been told to follow a special pre Petscan diet of low carbohydrates and no sugars for 24 hours before and avoid caffeine and heavy exercise. Since my Petscan is not until after noon on Wednesday I was planning on my usual breakfast of 2 cans of Jevity 1.5 through my feeding tube.so I would have fasted for six hours. Problem is that in looking at the nutrient label on the Jevity 1.5 cans I see that it is about 54% carbohydrates and of course mostly Sugar under a different name: Corn Maltodextrin (second ingredient by volume) and Corn syrup (third).

Since this is my third time around with this cancer, I need this Petscan to be accurate and not have unreliable SUV.
I've emailed my doctors to ask them if those diet instructions I got five years ago and four years ago when I had Petscans really mean I should not take my canned nutrient.

Unless they tell me otherwise, I'm going to play it safe and use my Vitamix to liquify some eggs and other low carb foods for dinner and breakfast.the night before and morning of the Petscan. I've only had MRIs since the permanent feeding tube so didn't think of this.
I will keep you posted on what, if any replies I get
