 * X-rays are a form of electromagnetic radiation.
 * X-rays have much higher energy and much shorter wavelengths than ultraviolet light. [[image:https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQBNq3VgK8pj7eG2EV6FPQiiyte_7X5vG3ajabcUMZESJW8oVK_ width="218" height="166" align="right"]]
 * X rays can penetrate the human body and produce images of structures such as bones, organs, and signs of disease and injury.
 * A PET scan is an imaging test that can help reveal how your tissues and organs are functioning.
 * A small amount of radioactive material is necessary to show this activity.
 * The type of radioactive material and its delivery method depend on which organ or tissue is being studied.
 * A SPECT scan is a type of nuclear imaging test that shows how blood flows to tissues and organs.
 * Radioactive drug is injected into a vein and a scanner is used.
 * Makes detailed images of areas inside the body where the radioactive material is taken up by the ce lls.
 * Shows function and structure of cardiovascular system.
 * A physician may recommend cardiac imaging to support a diagnosis.
 * Bone Scanning
 * "Bone scan is a specialized radiology procedure used to examine the various bones of the skeleton to identify areas of physical and chemical changes in bone" ("Bone Scan"1).
 * In a bone Scan a small amount of radioactive substances is used.
 * The radioactive substance is called a radionuclide and is used as a tracer and goes to spots in the tissue that are not normal
 * Radiation therapy uses radiation to kill cancer cells.
 * A side effect is that it can damage normal cells
 * A patient may receive radiation therapy at a certain time during, before ,or after surgery depending on the type of cancer being treated
 * The radiation used for cancer treatment may come from a machine or radioactive material placed in the body
