Has anyone had an arthrogram with contrast done to diagnose their torn acl or knee joint problem? The reason why I'm curious to know is because my orthopedist surgeon is sending me to get one done but I've read that the the Gadolinium (fluid dye) that is injected on the joint can cause infection and other adverse reactions such as tissue degeneration when combined with the radiation,,,,so,,,Im kinda skeptical about the whole procedure,,,and quite confused,,,I've already had 3 x-rays and 1 MRI done on the knee so I don't know if it can get worse from more radiation....
