Should I Be Worried About Radiation Exposure with My HeartLung Scan?

Radiation from x-rays is often misunderstood. X-rays are a form of energy, just like sunlight.

The difference is that the energy from x-rays can pass through your body and some of it gets absorbed. It’s absorbed differently by bones, organs, and tissues, which is the reason it can be used to create images that allow radiology doctors to see the internal structures. Thanks to x-rays, your health care providers can diagnose and treat many medical conditions.
