Could someone please tell me if the PET Scan, which the technician said would go from my thighs to me eyebrows, detects brain mets?

Thanks.

Cheryl, I'm told it doesn't. I think PET is not a great method for detecting brain mets...MRI better. Primarily b/c PET scans measure glucose uptake & highlight abnormal metabolic activity. The brain is constantly active, so the PET wouldn't give a true read of "abnormal" activity. I'm told that this is why after the radioactive glucose is injected, they have you sit by yourself, in the dark, to quiet your brain & allow those lesions & nodules have chance to "feed" & instead of doesn't getting sucked up by the brain.
I also learned recently that you shouldn't exercise right before a PET, b/c again, right after exercise, your muscles are hungry for "food" & will suck up all that radioactive glucose & may contribute to a false read.
Oh the things we learn on this journey...
Keep the faith!

no, you must have a brain specific CT or MRI

Love and light,

Tell the tech to go all the way up to top of head. I think most do anyway. It will show if there is a big tumor in brain, but is not real good with brain things. Mri is better.

The best way to detect brain mets is with a specific brain MRI. Pet SCANS ARE NOT recommended usually because the use of radiation instead of magnites as with MRI's. Radiation is not a problem initially, but contiuing scans is never used to follow-up. Scanning up to the eyebrow is not capturing the entire brain. It is the brain MRI that is recommended.

We are happy to reply to your inquiry.
