"Stanford Medicine Imaging’s goal is to reduce radiation dose exposure and provide the highest level of diagnostic quality images one patient at a time."

At Stanford Medicine Imaging, we understand that radiation exposure is a concern to patients and referring physicians. CT is a powerful imaging tool to diagnose a wide variety of disorders such as cancers, cardiovascular disease, infectious disease, trauma and musculoskeletal abnormalities. Stanford Medicine Imaging is committed to the radiation safety principles of ALARA (As Low As Reasonably Achievable):

For more than one hundred years, Stanford’s Department of Radiology has been making contributions to medical and surgical advances by pioneering innovations in image-based patient care, research, and education. We are preparing for the future with active research to discover new methods to optimize imaging and reduce radiation dose. Additionally, we are implementing innovative processes for cumulative dose tracking, notification and reporting.

How is ionizing radiation measured?

Radiation dose to the body is measured in units known as milliSieverts (mSv). The small amount of background radiation we all receive every year is about 3 to 5 mSv.
