After s/he does an official reading, s/he will send both a report and a disc to the chiropractor. Your chiropractor may look at the images, but, unless he is pathologically arrogant, will also read the report and defer to the radiologist''s reading.
And before you tell me that your chiropractor can read MRI's, I'm sure he can - to an extent. I can read xrays. I can tell you whether you have pneumonia or heart failure, whether you have a punctured stomach or intestine or are just full of shit (yes, that does show up on xray), or whether your neck is broken, among other things. But you would be ill-advised to take my conclusions - or your chiropractor's, since neither of us have done a four-year residency in radiology, and because neither of us does continuing education on it in the amount that a radiologist is required to.
