Why do you have to wait so long for results? In most places they are read in a couple of hours, at most, and the report is released electronically to the requesting doctor immediately when filed. You could probably go to the place where the scan is performed the next day--in some cases sooner--and pick up a copy of the report. (They may have to give you a CD also, but you don't have to actually do anything with it.) If you don't want to wait, ask them when you are in for the scan.
I do it every time.
