Hey Jessie, the 3 PET's were over the span of at least 5 years. When they do the PET they also do some sort of CT within the PET from what my Oncologist said. No ultrasounds. I have no symptoms of anything other than the excessive acid reflus and IBS my GI doc diagnosed. Had my PET this morning and discovered the PET DOTATATE probably was lighting up on some polyps in my stomach, which they removed this morning. They also did some biopsies of tissue which will take a few days to get results on. BTW, for what it's worth, I was wrong my my Chromagranin A levels. They were actually quite a bit higher at 22,899. My GI doc and I discussed a bit and he's at a loss as to why except for the PPI's and Kidney Disease. More when I get the actual results of the procedure.
