I am scheduled for a PET scan on Feb. 1 and am fairly apprehensive about it.
This is what I have learned about it.
At first radioactive glucose is administered (hope you are not diabetic).
Radioactive glucose, which cancer is happy to receive is than given a chance to flow true your body. You are laying on a gurney in a isolation room for 35 minutes while this process takes place. After 35 minutes you are no longer considered radioactive and are summoned to drink a substance to further highlight the problem areas in question.
Hankering for more fun, you are then submitted to a PET scan (newer technology than CT scan). However, the PET scanning requires 30 minutes of radiation (vs 3 min. with CT scan), hence delivering about 20 times more radiation than CT scan.
Not healthy, and I am very apprehensive about it.
