Additional Medical Terms Flashcards
adhesion
Band of scar tissue binding anatomical surfaces that are normally separate from each other
inflammation
Protective response of body tissues to irritation, infection or allergy
sepsis
Body’s inflammatory response to infection in which there is fever, elevated hear and respiratory rate, and low blood pressure
endoscopy
Visual examination of the interior of organs and cavities with a specialized lighted instrument called and endoscope
fluoroscopy
Radiographic procedure that uses a fluorescent screen instead of a photographic plate to produce a visual image from x-rays that pass through the patient, resulting in continuous imaging of the motion of internal structure and immediate serial images
MRI
Radiographic technique that uses electromagnetic energy to produce multi-planar cross-sectional images of the body
nuclear scan
Diagnostic technique that produces and image of and organ or area by recording the concentration of a radiopharmaceutical (the combination of a radioactive substance called a radionuclide and another chemical) introduced into the body
radiography
Production of captured shadow images on photographic film through the action of ionizing radiation passing through the body from an external source
radiopharmaceutical
Drug that contains a radioactive substance which travels to an area or a specific organ that will be scanned
scan
Technique for carefully studying an area, organ, or system of the body by recording and displaying an image of the area
tomography
Radiographic technique that produces a film representing a detailed cross-section, or slice, of an area, tissue, or organ at a predetermined depth
CT
Radiographic technique that uses a narrow beam of x-rays that rotates in a full arc around the patient to acquire multiple view of the body that a computer interprets to produce cross-sectional images of that body part
PET
Radiographic technique combining computed tomography with radiopharmaceuticals that produces a cross-sectional image of the dispersement of radioactivity in a section of the body to reveal the areas where the radiopharmaceutical is being metabolized and where there is a deficiency in metabolism
SPECT
Type of nuclear imaging study that scans organs after injection of a radioactive tracer and employs a specialized gamma camera that detects emitted radiation to produce a three-dimensional image from a composite of numerous views
US
Imaging technique that uses high-frequency sound waves that bounce off body tissues and are recorded to produce and image of an internal organ or tissue
