X-ray is the oldest and most frequently used form of medical imaging. It is also the fastest, and easiest and most economical way for a physician to view and assess broken bones.

It can also be used to diagnose and monitor the progression of diseases, including osteoporosis, heart disease and cancer. Unlike other forms of radiation, X-rays can easily pass through body tissue, making it possible to provide images of internal structures without performing surgery.

During the procedure, electromagnetic radiation passes through the body onto “film” (now digitized and displayed on a computer screen). Dense structures such as bone absorb most of the radiation and appear white on the digital image. Structures that are less dense like air appear black. Everything in between appears a different shade of gray.
