| What is an x-ray? |
| An x-ray or radiograph is one of the most commonly used techniques in radiology for imaging internal structures of the body. An x-ray image is produced when a small amount of radiation passes through the body and strikes a sheet of sensitive film. The exposed radiographic film shows body structures in relation to their density. Bone has a high body tissue density so it absorbs more x-rays, resulting in white or nearly clear images on the film. Where x-rays are least hampered in their path, such as through air in the lungs, the film is darkest. The differences in shading between the extremes of tissue densities allow x-rays to outline organs, reveal structural abnormalities and pinpoint a disease location. |

What are the reasons for having an x-ray? |
Radiographs are a reliable and accurate means of obtaining information to help diagnosis the cause of pain. An x-ray exam is commonly used to determine the presence or absence of disease, a bony fracture, joint misalignment, arthritis or the source of other painful conditions. |

Are x-rays safe? |
| X-ray uses ionizing radiation. The technologists at WIS are experts in utilizing the minimal dose to achieve optimal results. Lead aprons and shields are used and the equipment is routinely inspected for safety and adequate shielding. All examinations are well within permissible levels of diagnostic radiation dosage. However, be sure to notify the technologist if there is a chance of pregnancy. |

What are the alternatives? |
| Alternate diagnostic tests such as MRI or ultrasound may be performed without utilizing ionizing radiation, however their use is dependent on your condition and the information your doctor requires. |
