Exercise before PSMA PET scan

dhccpa profile image

I'm having my first ever PSMA PET on Wednesday. Instructions say only to hydrate well--no other restrictions.

I want to exercise the morning before (about 26 hours) before scan, and wanted to see if anyone had any contrary opinions.

I ask because when doing Axumin PETs one instruction was to not exercise 24-48 hours before.

hi! I did not have such restriction, but isn't there a reference manual?

I don't know. I've always followed clinic directions, but this scan is more important than ever.

then do not exercise, that's the safest option

Just to clarify, the restriction on exercise was on previous Axumin PET scans.

No such restriction from the clinic for the upcoming PSMA PET scan. I'm just seeing what others were told for PSMA scan specifically.

They didn't inform me of any exercise restriction prior to my Axumin scan. Just sayin'.

Yes, I get them at least once a year, sometimes twice. Had one 6 months ago and having another in September. My MO is super cautious with use of a PARP inhibitor

PSMA PET requires good liver and kidney function for purging the residuals, hence the hydration requirement which as a side benefit makes canula insertion easier. It is then a matter of balancing hydration and exercise. I would not be concerned the day prior. And my annual PET is this month so been there, done that.😀

Cannula?…..I had no cannula for my psma….or you referring to the IV port?

RS265 profile image
RS265 in reply toTommyj2

Ports are typically implanted for longer term use/access. I suspect we are both referring to the same temporary IV line.

i’ve had multiple PSMA scans at UCLA in the last four years. Each time, Dr. Kushan’s staff has given me a list of dues and don’ts prior to PSMA scan and this includes no heavy exercise for 24 hours unsure of the reason though.

Interesting in Australia no such restrictions that i know of

dhccpa in reply toBrianne07

I suspect some clinics just routinely advise this. Mine did not. But some PET scans do require no exercise.

I've had the scan 3X and was advised each time not to do any heavy exercise for 24 hours beforehand.

I go for my PSMA SCAN in 2 weeks, and instructions say no vigorous exercise 24 hrs prior.

I have had MANY MANY scans including many PSMA scans. All have said no vigorous exercise on the day of the scan or the day before.Also once I crashed on a bike and that was a couple weeks before the scan but the scan picked up a positive in my back. As it turned out that was in a clinical trial of PSMA vs Choline. The Choline was the one picking up that inflammation caused by the crash, the PSMA did not pick it up.

Exercise should have zero effect on test.Cancer doesn't care.

dhccpa profile image
dhccpa in reply tocarbide

Yes but instructions for some types of PET scan clearly advise against it. This one didn't, hence my post. And the reactions have been mixed. It's not the cancer, as I understand, but whether exercise can cause distortions in the scan results.

I see no reason at not to exercise. The ONLY recommendation for PSMA pet is to be well hydrated.

Have said that, my latest PSMA pet referral says “fast for 4 hours”. I KNOW that is not a requirement. So I’m guessing they just pasted the info they would use for a glucose based pet. Sometimes I think they don’t really carefully check the recommendation for a specific PET and just go with generic instructions.
