In general, it takes 24/48hrs for the contrast to be completely eliminated from the body when the kidneys are functioning well. For people with kidney problems, it takes longer than usual for it to be eliminated. So it is essential to be well hydrated before and after receiving the contrast to help flush the contrast from the body and reduce the risk of acute kidney injury.
