Section 1

Question Answer
endoscopythe visual examination of the interior of a body cavity
endoscopic surgerysurgical procedure performed through very small incisions with the use of an endoscope and specialized instruements
endoscopea small flexible tube with a light and a lens on the end
laparoscopythe visual examination of the interior of the abdomen with the use of a laparoscope that is passed through a small incision in the abdominal wall
centesisa surgical puncture to remove excess fluid or to remove fluid for diagnostic purposes
abdominocentesisthe surgical puncture of the abdominal cavity to remove fluid
arthrocentesisthe surgical puncture of a joint space to remove synovial fluid for analysis to determine the cause of pain or swelling within a joint
cardiocentesisthe puncture of a chamber of the heart for diagnosis or therapy
pericardiocentesisthe puncure of the pericardial sac for the purpose of removing fluid

Section 2

Question Answer
imaging techniquesused to visualize and examine internal body structures
radiography (x-ray)uses x-radiation passing through the patient to expose a film or create a digital image that shows the body in profile.
computed tomography (CT)uses x-radiation with computer assistance to produce multiple cross-sectional views of the body.
contrast mediumused to make specific body structures visible
radiopaquethe substance does not allow x-rays to pass through
radiolucentthe substance does allow x-rays to pass through
intravenous contrast mediuminjected into a vein to make the flow of blood through blood vessels and organs visible
bariuma radiopaque contrast medium used primarily to visualize the gastrointestinal tract; radiography and fluoroscopy are used to trace the flow of the barium
radiologycreates an image of hard-tissue internal structures by the exposure of sensitized film to x-radiation
radiographfilm that results from a radiology
radiopaque hard tissueappear white or light gray on a radiograph; bone, tooth
radiolucent soft tissueappear as shades of gray to black on a radiograph; muscle, skin
radiologistphysician who specializes in diagnosing and treating diseases and disorders with x-rays and other forms of radiant energy
interventional radiologythe use of radiographic imaging to guide a procedure such as a biopsy.; also used to confirm the placement of an inserted object such as a stent or feeding tube

Section 3

Question Answer
radiographic positioningdescribes the placement of the patient's body and the part of the body that is closest to the x-ray film
radiographic projectiondescribes the path that the x-ray beam follows through the patient's body from the entrance to the exit
extraoral radiographythe film is placed and exposed outside the mouth
panoramic radiographicshows all the structures in both dental arches in a single film
intraoral radiographythe film is placed within the mouth and exposed by a camera positioned next the exterior of the cheek
computed tomographyuses a thin, fan-shaped x-ray beam that rotates around the patient to produce multiple cross-sectional views of the body
tomotherapy the combination of tomography with radiation therapy to precisely target the tumor being treated; radiation is delivered slice-by-slice to the tumor and is able to avoid healthy tissue
magnetic resonance imaginguses a combination of radio waves and a strong magnetic field to create signals that are sent to a computer and converted into images of any plane through the body
magnetic resonance angiographyhelps locate problems within blood vessels throughout the body
fluoroscopythe visualization of body parts in motion by projecting x-ray images on a luminous fluorescent screen
cineradiographyrecording of the fluoroscopy images
ultrasonographyimaging of deep body structures by recording the echoes of sound wave pulses that are above the range of human hearing
sonogramthe image created by ultrasonography
carotid ultrasonographythe use of sound waves to image the carotid artery to detect an obstruction that could cause an ischemic stroke
echocardiographyan ultrasonic procedure used to evaluate the structures and motion of the heart
Doppler echocardiogrammeasures the speed and direction of the blood flow within the heart
fetal ultrasoundnoninvasive procedure used to image and evaluate fetal development during pregnancy
transesophageal echocardiographyultrasonic imaging technique used to evaluate heart structures;this test is performed from inside the esophagus
