@rx2rich Before you have that CAT scan, I would ask to make sure your eGFR is at a good level. Contrast material can be hard to clear from the kidneys when our function is lowered [usually anything from 30 or lower should be careful for contrast scans].

Since the initial MRI was not for the kidneys, I hope you are able to get that appointment sooner than later. Ask them to be placed on a cancellation list; that might speed the response. Call and ask what the hold up is to getting an appointment!
