No, identifying the tumor is only step 1, and is the easiest step. Most non-radiologists can identify whether a tumor is present. The harder part (and the true value of radiologist reads) is everything that comes after finding the tumor: what structures are the tumor invading? Is there spread to lymph nodes? Are there secondary findings that might affect the diagnosis or treatment?

These questions and their relevance changes for every individual case, and while each question by itself may be approachable with AI, getting a detailed and relevant report without meaningless noise from an AI ensemble is a very very hard problem.
