Abstract: A system that can be used for targeted radiology resident training can include a memory storing computer-executable instructions and a processor to access the memory and execute the computer-executable instructions to at least receive a preliminary report and a corresponding final report; determine a difference between the final radiology report and the preliminary radiology report; classify the difference as substantive or stylistic based on a property of the difference; and produce an output including the difference when classified as substantive. The output can include one or more critical errors reflected in the substantive difference. The one or more critical errors can be used to facilitate radiology resident training.
