However, do you really trust even the radiologist reads of your MRIs and CTs? In many instances (as they do not have an accurate history), their readings are usually flawed, as they miss the forest for the trees. How many times have you found far lateral discs that explain the patient's symptoms perfectly, while a two paragraph radiology report is focusing on all the other irrelevant findings?
And when radiologists describe stenosis, how many actually state the canal dimensions in mm or instead use "mild", "moderate", or "severe", which is arbitrary and in most instances tells you nothing?
Worse yet, the guys who will put ridiculous "readings" like "possible discitis" in the report when there are just Modic III degenerative changes that they simply won't call? It causes more harm than good, as one is medico-legally forced to order additional testing, simply because an incorrect read is put on the record in the first place.
I just look at the report afterward to see if there is anything they can add, and that is usually pretty rare.
Radiologists are going to be replaced first by contract docs overseas and then artificial intelligence. AI will make that whole specialty irrelevant in 20 years.
