  1. CT
    • (computed tomography) -
    • uses a narrow beam of x-rays, which rotates in a full arc around the patient to image the body in cross-sectional
    • slices.
  2. fluoroscopy
    directs x-rays through the body to a fluorescent screen to view the motion of organs, such as digestive system.
  3. US
    (ultrasonography) - employs high-frequency sound waves to produce images of internal structures of the body.
  4. MRI
    (magnetic resonance imaging) - employs magnetic energy (without ionizing x-rays) to produce cross-sectional images.
  5. PET
    (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.
  6. endoscope
    is a specialized lightened instrument to view the interior of organs and cavities.
  7. anastomosis
    surgically joins two ducts blood vessels, or bowel segments to allow flow from one to another.
  8. SPECT
    (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.
  9. tomography
    produces a film representing a detailed cross section of tissue structure at a predetermined depth; three types include CT, PET, and SPECT.
  10. radiopharmaceutical
    is a drug that contains a radioactive substance that travels to an area or specific organ to be scanned.
  11. endoscopy
    is a procedure to enable visualization of the interior of organs and cavities with a lighted instrument.
  12. cauterize
    is a procedure to burn abnormal tissue with electricity, freezing, heat, or chemicals.
  13. adhesion
    is a band of scar tissue that binds anatomical surfaces that normally are separate from each other.
  14. radiography
    is production of shadow images on photographic film.
  15. sepsis
    is the body’s inflammatory response to infection, in which there is fever, elevated heart rate and respiratory rate, and low blood pressure.
