Therapeutic Radiology in California

13 providers, $43,256 in total reported payments from drug and device makers. Ranked below by lifetime general payments.

Ranking high here usually means a consulting or royalty arrangement, not wrongdoing. Payments to device inventors and trial investigators are legal, disclosed, and concentrated in a small number of people — which is exactly why a list like this has a steep top and a long flat tail.
