X-rays

An X-ray, also called a radiograph, is a medical imaging test that helps doctors diagnose and monitor a variety of conditions. X-rays use a small amount of ionizing radiation to create images of structures inside the body.

During an X-ray, radiation passes through the area of the body being examined to create an image. Dense structures, such as bones, absorb more radiation and appear white on an X-ray. Softer tissues allow more radiation to pass through and appear in shades of gray.

Most X-rays require little to no special preparation. Your care team will let you know if you need to follow any specific instructions before your exam.
