It's not too hard to train yourself to identify sex or approximate age. (I claim this because of time spent reviewing model output for work that I have done to build models to estimate age.) The reason radiologists don't do this is that there is no clinical reason to do it, so it's not a skill that they develop. (Deep neural networks can also beat radiologists at bird classification, another task that is not relevant for their job.)
