The Purpose and Procedure of X-ray Imaging
If your doctor or dentist says you need an X-ray, it’s time for your bones to smile for the camera. An X-ray takes a picture of the inside of your body. Doctors use them to diagnose:
- Broken bones
- Dislocated joints
- Arthritis
- Abdominal pain, in some instances
- Cancer
- Tooth decay
Doctors can also use X-rays to find an object that a child swallowed or to check your lungs for signs of pneumonia or tuberculosis.
