X rays are radiation of short wavelengths which are produced when electrons hit a solid target. In the medical sense X rays are used to get a picture of the internal structure of the body namely the bones. When an X ray is taken a film is put on the other side of the body and a shadow is produced. As different parts of the body absorb the rays differently the resulting picture can be interpreted easily.
- Check the patients name is correct
- Check the date, time & relevant health system numbers
- Check how the image was taken PA vs. AP. (PA = through back of patient, AP= through front)
- Check whether Supine or Erect
QUALITY OF IMAGE EXPOSURE
- Pathologies may be missed if the image is under/over exposed
- The interverterbral disc spaces should be visualized behind the heart
- The pulmonary vasculature should be visualized
CHECK FOR ADDITIONAL INFORMATION
- Rotation? (Make sure the distance from each clavicle is equal)
- Start from the center of the image and work your way out to the periphery.
- Look at the heart, mediastinum, lungs, pleural space, ribs, clavicles, diaphragm, subcutaneous tissues, neck and upper abdomen
- Check Radiological Items
- Fields (Lungfields)
- Gastric Air Bubble
WHAT ARE YOU SEEING?
WHITE = Bone (high absorption of X rays)
BLACK = Air
GREY = Tissue (low absorption of X rays)
