Pump and PET scan strategies

Type 1 and LADA
1

I’m currently scheduled for my periodic PET scan. As most know, one has to fast before the scan. I’m always worried that my glucose will fall below the acceptable limits.

What strategies are others employing to keep that glucose level within acceptable bounds? I have a profile on my Tandem pump that I set at 0.5 u/hr. However, I’m not secure in the knowledge that the half-unit will suffice.

Looking for constructive input and game plans.

Thank you - Fame

I found this PET scan prep instructions from Jupiter Med. I don’t know if it is helpful. You might show this to who is doing your scan. The one thing that stood out to me is at the end.
“ If your fasting morning glucose tends to be under 70mg/dl, please drink a glass of juice before coming for your PET Scan appointment. Your serum glucose will be closely monitored.”

Good Morning Luis3:

Thanks for your feedback. I’ve read all of the hospital guidelines regarding a PET scan for diabetics. Unfortunately, none address the question I pose.

“If your fasting morning glucose tends to be under 70mg/dl, please drink a glass of juice before coming for your PET Scan appointment”

Drinking anything, with the exception of water is strictly disallowed. That in a nutshell is the point of my question.

You leave for your PET appointment (glucose levels are good) and between the isotope injection and the 1 hour wait time pre-PET, your glucose continuously drops.

Appointment canceled. The roundtrip drive time is two hours. Wasted day! Just part of the many joys a type 1 encounters

I just wonder why this group allows the juice, while your’s doesn’t.

idea: Drinking nothing doesn’t exclude dissolving glucose tabs in your own saliva.

Glucose is what a PET scan highlights. The cellular activity takes up glucose. So, no, glucose tabs would be exactly what isn’t wanted. It would skew the test results, making cellular activity indistinguishable from the ingested glucose tabs.
