This article describes the indications for breast MRI and discusses the pros and cons of using it to screen women for cancer and evaluate the extent of disease in women who are newly diagnosed.

Publicized cases of errant high radiation exposure delivered to patients undergoing diagnostic imaging have led to heightened awareness and scrutiny of the costs and benefits of imaging by physicians, the public, and policymakers. The statistical risks associated with the ever-increasing utilization of modalities employing damaging ionizing radiation across the population are compounded by the development of the latest generation of devices, which are capable of delivering greater radiation doses than their predecessors for comparable diagnostic applications. This article reviews the fundamental concepts and risks of medical radiation exposure, trends in imaging utilization, and the role of radiologists and their physician colleagues in managing and appropriately utilizing imaging for patient diagnosis.
