Exam Details - X-Ray General
Available at:
DC, Bethesda, Fairfax, Sterling and Chevy Chase
Used To:
- View bones and soft tissue
Why:
- Many reasons for exam
How:
- X-ray passes through the body and are detected by sensors
- The black, white, and gray on an image depends on the body part's mass and composition
- Bone contains calcium, which is dense tissue
- This does not allow much radiation to penetrate through, resulting in white images on the x-ray film
- Example: The lung filled with air allows nearly all radiation to strike the film, resulting in a black image
- This is useful in detecting fracture and destruction of bone structures
