An X-ray is a type of medical scan. Several types of scanning tests can be used to make a diagnosis, depending on the situation. An X-ray is primarily used to determine if there is damage to bones such as a fracture or dislocated joint, locate a foreign object (i.e., bullet, a swallowed toy, etc), diagnose certain diseases (example-pneumonia) or to get a general idea of where to focus a more detailed scan of soft tissues. It is performed by placing the patient between a specialized type of film and a radiation source, which can be targeted at any given point of the body. It creates a picture that is then viewed by an X-ray technician, nurse, physician assistant or physician in order to help make his/her diagnosis. There are also CAT scans, MRI's, ultrasounds, and PET scans, all of which use different technology to be able to view inside the body in varying levels of detail.
