Flashcards in Endoscopy Centesis and Radiology Deck (31):
the visual examination of the interior of any cavity by means of an endoscope.
a procedure using an endoscope to aid in surgical procedures so that only very small incisions are made.
the surgical puncture to remove fluid or gas for diagnostic purposes or for treatment.
a sharp, needlelike instrument that has a cannula (tube) that is used to puncture the wall of a body cavity to withdraw fluid or gas.
a hollow tube.
the procedure in which film is exposed as ionizing radiation passes through the patient and shows the internal body structures in profile.
an x-ray or record of ionizing radiation used to visualize internal body structures.
means record when talking about radiology
appearing white or light gray on a radiograph because ionizing radiation does not penetrate these structures well.
appearing black or dark gray on a radiograph because ionizing radiation passes quickly through these structures.
the study of internal body structures after exposure to ionizing radiation.
a plain radiograph made without the use of a contrast medium.
Radiographic contrast medium
a substance used to show structures on X-ray that are otherwise difficult to see.
Barium sulfate or barium
one example of contrast material.
a type of contrast radiograph used to visualize the structures of the lower gastrointestinal tract.
the method of introducing contrast material into the colon
a type of contrast radiograph used to visualize the structures of the upper gastrointestinal tract.

the path of the x-ray beam
the specified body position and the part of the body closest to the film.
used in reference to positioning
refers to the animal in its normal standing position.
the procedure in which ionizing radiation with computer assistance passes through the patient and shows the internal body structures in crosssectional views
CT scan/CAT scan
Another term for Computed tomography.
a recording of the internal body structures at predetermined planes that produces three-dimensional images.
Magnetic resonance imaging
the procedure in which radio waves and a strong magnetic field pass through the patient and show the internal body structures in three-dimensional views.
the procedure used to visually examine internal body structures in motion using radiation to project images onto a fluorescent screen as light
giving off a soft light
the imaging of internal body structures by recording echoes of high frequency sound waves.
