High yield areas for CT on the USMLE are head and abdomen. Be able to pick out the aorta, liver, kidney and pancreas in the abdomen and know the diff between epidural/subdural/SAH for the head.
MRI is very low yield on USMLE. I didnt have one question with an MRI.
Good anatomy questions often involve muscles innervated by/supplied by what nerves/arteries (i.e. what function is limited when the common peroneal nerve is damaged, etc), also embryology of organs, trauma to joints (what ligament/tendon/nerve) is affected
