Just to provide some data on the radiation dose. It’s everyone’s own decision whether a ‘willy-nilly’ PET scan is worth it.

From the English Wikipedia:

FDG, which is now the standard radiotracer used for PET neuroimaging and cancer patient management, has an effective radiation dose of 14 mSv.

The amount of radiation in FDG is similar to the effective dose of spending one year in the American city of Denver, Colorado (12.4 mSv/year). […T]he whole body occupational dose limit for nuclear energy workers in the US is 50 mSv/year.

From the German Wikipedia:

Es ist bei einer Strahlendosis von 1 Sievert (Sv), der 100 Menschen ausgesetzt sind, mit 5 Todesfällen durch Strahlenkrebs zu rechnen […]. Man müsste also 100.000 PET-Untersuchungen durchführen, um 35 Todesfälle an Strahlenkrebs (nach einer mittleren Latenzzeit von etwa 15 Jahren für Leukämie und etwa 40 Jahren für solide Tumoren) zu verursachen, das heißt etwa eine auf 3000 Untersuchungen

If 100 people received a radiation dose of 1 Sievert (Sv), one would expect 5 deaths due to radiation-induced cancer […]. One would need 100,000 PET scans in order to cause 35 cancer deaths (after a median wait duration of 15 years for leucemia and 40 years for solid tumors), which is about 1 in 3000 scans.

I mean 1 in 3000 isn't a lot, but it's a lot more than nothing...
