  1. Adhesion
    abnormal fibrous band that hold or binds together tissues that are normally separated
  2. analyte
    substance analyzed or tested, generally by means of laboratory methods
  3. contrast medium
    substanc imjected into the body, introduced via catheter, or swallowed to facilitate radiographic images of internal structures that otherwise are difficult to visualize on xray films
  4. dehiscense
    bursting open of a wound, especially a surgical abdominal wound
  5. febrile
    feverish; pertaining to a fever
  6. nuclear medicine
    branch of medicine concerned with the use of electromagnetic radiation, ultrasound, and imaging techniques for diagnosis and treatment of disease an injury
  7. radionuclides
    substances that emit radiation spontaneously; also called tracers
  8. radiopharmaceutical
    radionuclide attached to a protein, sugar or other substance used to visualize an organ or area ofthe body that will be scanned
  9. sepsis
    pathological state, usually febrile, resulting from the presence of microorganisms or their products in the bloodstream
  10. suppurative
    producing or associated with generation of pus
  11. endoscopy
    visual examination of a body cavity or canal using an endoscope
  12. laparoscopy
    visual examination of the organs of the pelvis and abdomen through very small incision in the abdominal wall
  13. thoracoscopy
    examination of the lungs, pleura, and pleural space with a scope inserted through a small incision between the ribs
  14. complete blood count (CBC)
    common blood test that enumerates RBC's, WBC's and platelets; measures hemoglobin; estimates red cell volume; and sorts WBC's into 5 subtypes with their percentages
  15. urinalysis
    common urine screening test that evaluates the physical, chemical, and microscopic properties of urine
  16. computed tomography (CT)
    imaging technique acheived by rotating an x-ray emitter around the area to be scanned and measuring the intensity of transmitted rays from different angles
  17. Doppler
    ultrasound technique used to detect and measure blood-flow velocity and direction through the cardiac chambers, valves, and peripheral vessels by reflecting sound waves off moving blood cells
  18. fluoroscopy
    radiographic technique in which x-rays are directed through the body to a fluorescent screen that displays continuous motion images of internal structures
  19. magnetic resonance imaging (MRI)
    noninvasive imaging technique that uses radiowaves and a strongmagnetic field rather than an x-ray beam to produce multiplanar cross-sectional images
  20. nuclear scan
    diagnostic technique that uses a radioactive material called a tracer that is introduced into the body and a specialized camera to produce images of organs and structures
  21. positron emission tomography (PET)
    scanning technique using computed tomography to record the positron ( + charged particles) emitted from a radiopharmaceutical, that produced a cross-sectional image of metabolic activity in body tissues to determine the presence of disease
  22. radiography (ra-de-OG-ra-fe)
    imaging technique that uses x-rys passed through the body or area and captured ona film; also called x-ray.
  23. single photon emission computed tomography (SPEC)
    radiological technique that integrates CT and a radioactive material (tracer) injected into the bloodstream to visualize blood flow to tissue and organs
  24. tomography
    radiographic technique that produces an image representing a detailed cross-section, or slice, of an area, tissue, or organ at a predetermined depth.
  25. ultrasonography (US)
    imaging procedure using high-frequency sound waves (ultrasound) that display the reflected "echoes" on a monitor (called ultrasound)
  26. biopsy
    represented tissue sample removed from a body site from microscopic examination, usually to establish a diagnosis
  27. ablation
    removal of a part, pathway, or function by surgery, chemical destruction, electrocautery, freezing, or radio frequency
  28. anastomosis
    surgical joining of two ducts, vessels, or bowels segments to allow flow from one to another
  29. cauterize
    destroy tissue by electricity, freezing, heat, or corrosive chemicals
  30. curettage
    scraping of a body cavity with a sppon-shaped intrument called a curette
  31. incision and drainage (I & D)
    insicion made to allow the free flow or withdrawal of fluid from a wound or cavity
  32. laser surgery
    surgical technique employing a devise that emits intense heat and power at close range to cut, burn, vaporize, or destroy tissue.
  33. radical dissection
    surgical removal of tissue in an extensive area surrounding the surgical site in an attempt to excise all tissue that may be malignant an decrease the chance of recurrence
  34. resection
    partial excision of a bone, organ, or other strucures
