Radiation and Imaging

by Hakan Ilaslan, MD

Imaging helps with initial diagnosis, staging, and monitoring. Primary care physicians and specialists work with radiologists who specialize in diagnostic imaging to choose the best imaging test; choice is based on the type of lesion suspected and its anatomic location.
