X-ray radiography is an imaging method using X-rays. It exposes a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging.
Computed tomography (CT)—sometimes called CAT scanning—is a non invasive, painless medical test that helps physicians diagnose and treat medical conditions. This type of imaging uses special x-ray equipment to produce multiple images or pictures of the inside of the body and a computer to join them together in cross-sectional views of the area being studied. The images can then be examined on a computer monitor or printed.
Angiography is a type of x-ray that is done to image blood vessels in various parts of the body, including the heart, brain and kidneys, so as to determine whether the vessels are diseased, narrowed, enlarged or blocked altogether.
Mammography is a specific type of imaging that uses a low-dose x-ray system to examine breasts.
Fluoroscopy is an imaging technique commonly used by physicians to obtain real-time images of the internal structures of a patient through the use of a fluoroscope. In its simplest form, a fluoroscope consists of an x-ray source and fluorescent screen between which a patient is placed.
