You should have a DR letter. Try to learn your advanced liver imaging (lirads) (CT liver/MRI liver) . Get good at your renal CT and MRI . Get good at surgical conditions (imaging features of cholecystitis on us/HIDA). Also try to get comfortable with vascular imaging (CTA/MRA/vascular us). Try to shadow a body attending during readouts and see as much surgical pathology as possible. This will help you with your surgical internship. If really having a hard time working with an attending on readouts consider doing a case report with one of the attending on one of the interesting imaging cases you see.
