MRI and Ultrasound

Ultrasound and MRI do not use ionizing radiation and have no risk of inducing cancer. While excellent for many things, MRI and Ultrasound are often not the best test and CT scans or x-rays are preferred. Talk to your healthcare provider about imaging options and what is best for you.

Please see Glossary for description of different studies.

Keep in mind, the overall lifetime risk of developing an invasive cancer is 37.5% (1 in 3) for women and 44.9% (1 in 2) for men regardless of imaging history. These statistics are averages and do not predict what is going to happen to you. They do not take into consideration individual risk factors including lifestyle (smoking, diet, exercise, etc), family history (genetics) or radiation exposure. The majority of cancers occur later in life and the average lifetime risk of dying from cancer is 25% (1 in 4).
