uses a narrow beam of x-rays, which rotates in a full arc around the patient to image the body in cross-sectional
directs x-rays through the body to a fluorescent screen to view the motion of organs, such as digestive system.
(ultrasonography) - employs high-frequency sound waves to produce images of internal structures of the body.
(magnetic resonance imaging) - employs magnetic energy (without ionizing x-rays) to produce cross-sectional images.
(positron emission tomography) - is a type of nuclear scan that uses radiopharmaceuticals to diagnose disorders involving metabolic processes, such as brain tumors, epilepsy, stroke, Alzheimer disease, and pulmonary disorders.
is a specialized lightened instrument to view the interior of organs and cavities.
surgically joins two ducts blood vessels, or bowel segments to allow flow from one to another.
(single-photon emission computed tomography) - is similar to PET, but employs a specialized gamma camera that detects emitted radiation to produce a three-dimensional image based on a composite of many views.
produces a film representing a detailed cross section of tissue structure at a predetermined depth; three types include CT, PET, and SPECT.
is a drug that contains a radioactive substance that travels to an area or specific organ to be scanned.
is a procedure to enable visualization of the interior of organs and cavities with a lighted instrument.
is a procedure to burn abnormal tissue with electricity, freezing, heat, or chemicals.
is a band of scar tissue that binds anatomical surfaces that normally are separate from each other.
is production of shadow images on photographic film.
is the body’s inflammatory response to infection, in which there is fever, elevated heart rate and respiratory rate, and low blood pressure.
