An X-ray is a quick, painless test that produces images of the structures inside your body — particularly your bones. X-ray beams pass through your body, and they're absorbed in different amounts depending on the density of the material they pass through. Dense materials, such as bone and metal, show up as white on X-rays. The air in your lungs shows up as black, while fat and muscle appear as shades of gray.
We’ll use X-ray technology to examine parts of the body.
- Fractures and infections. In most cases, fractures and infections in bones show up clearly on X-rays.
- Arthritis. X-rays of your joints can reveal evidence of arthritis. X-rays taken over the years can help your doctor determine if your arthritis is worsening.
- Osteoporosis. Special types of X-ray tests can measure your bone density.
