I mentioned on a thread somewhere that it takes a few days to get the report on the disk. After all, the radiologist has to look at the films, then dictate the report, and then it has to be typed. Usually for me that takes a couple of days.
My advice would be to remember that radiologists like other specialists have a lot of education in order to read films, and MRI's are another ball game altogether. So I think you could drive yourself bonkers if you try to interpret it!
