Body structure/ directional Flashcards
adhesion
band of scar tissue binding anatomical surfaces that normally are 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 heart and respiratory rate, and low blood pressure
computed tomography (CT) scan
radiographic technique that uses a narrow beam of x-rays, which rotates in a full arc around the patient to image the body in cross-sectional slices. A scanner and detector send the images to a computer,which consolidates all of teh data it receives from the multiple x-ray views
endoscopy
visual examination of the interior of organs and cavities with a specialized lighted instrument (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. The technique offers continuous imaging of the internal structures and immediate serial images.
magnetic resonance imaging (MRI)
radiographic technique that uses electromagnetic energy to produce multi planar cross-sectional images of the body
nuclear scan
diagnostic technique that produces an image by recording the concentration of a radiopharmaceutical.
<p>
| positron emission tomography (PET)</p>
<p>
combines CT and radiopharmaceuticals. Produces a cross-sectional (transverse) image of the dispersement of radioactivity to reveal where being metabolized and where there is a deficiency in metabolism</p>
<p>
</p>
radiography
production of captured shadow images on photographic film through the action of ionizing radiation passing through the body from and external source
radiopharmaceutical
drug that contains a radioactive substance that travels to an area or a specific organ that will be scanned
scan
technique for carefully studying an area, organ, or system of teh body by recording and displaying an image
single-photon emission computed tomography
type of nuclear imaging study to scan organs after injecting radioactive tracer. Employs gamma camera to detect emitted radiation to produce 3D image
tomography
radiographic technique that produces a film representing a detailed cross-section of tissue structure at a predetermined depth
ultrasonography
imaging technique that uses high frequency sound waves (ultrasound) that bounces off body tissues and are recorded to produce an image of an internal organ or tissue. Ultrasonic echoes are recorded and interpreted by a computer, which produces a detailed image of the organ or tissue.
anastomosis
connection between two vessels; surgical joining of two ducts, blood vessels, or bowel segments to allow flow from one to the other
cauterize
process of burning tissue by thermal heat, including steam, electricity, or other (lase, dry ice)
cytologist
usually a biologist who specializes in the study of cells, especially one who uses cytologic techniques to diagnose neoplasms
cytology
study of cells
histology
study of tissue
dorsal
back (of body)
lateral
side, to one side
ventral
belly, belly side
anterior
front of the body
