No hospital takes a few days to read an MRI. This is not true. You either dont know what you are talking about or are lying.
MRI's are usually read within MINUTES not hours of completion. Any hospital that allowed MRI's not to be read for hours would have lawsuits out the wazzzo in no time.
The physician has the results in an hour or two, btu probably doesnt get around to reading the radiologists notes for a day or two or three or four etc. Call the dr.s office and ask the next day and they should have them.
