In my business I read MRI and CT reports all the time and whenever evidence of a prior surgery is seen it is noted and commented on in exactly this fashion and it does sound like pretty standard language. If there was something abnormal- a finding that was not expected- your doctor would have called you.
It’s also industry standard that a doctor that orders a CT or MRI scan discusses the findings with the patient by phone or sets up an appointment to do so. I have read countless records or orthopedic surgeons and the pros always schedule a follow up after an MRI. So I am not really sure why you got left twisting in the wind on this. Most of my docs who order tests communicate with me by email on the results. Even blood labs - I get emails on both the test results and the doctor’s interpretation of them. This is 2019 and this is how real pros operate.
