a hollow tube.

Question 6

Radiography

Answer 6

the procedure in which film is exposed as ionizing radiation passes through the patient and shows the internal body structures in profile.

Question 7

radiograph

Answer 7

an x-ray or record of ionizing radiation used to visualize internal body structures.

Question 8

graph

Answer 8

means record when talking about radiology

Question 9

Radiopaque

Answer 9

appearing white or light gray on a radiograph because ionizing radiation does not penetrate these structures well.

Question 10

Radiolucent

Answer 10

appearing black or dark gray on a radiograph because ionizing radiation passes quickly through these structures.

Question 11

Radiology

Answer 11

the study of internal body structures after exposure to ionizing radiation.

Question 12

Scout film

Answer 12

a plain radiograph made without the use of a contrast medium.

Question 13

Radiographic contrast medium

Answer 13

a substance used to show structures on X-ray that are otherwise difficult to see.

Question 14

Barium sulfate or barium

Answer 14

one example of contrast material.

Question 15

Lower GI

Answer 15

a type of contrast radiograph used to visualize the structures of the lower gastrointestinal tract.

Question 16

Barium enema

Answer 16

the method of introducing contrast material into the colon

Question 17

Upper GI

Answer 17

a type of contrast radiograph used to visualize the structures of the upper gastrointestinal tract.

Question 18

Barium swallow

Answer 18

contrast material that is injected intravenously.

Question 19

lymphangiography

Answer 19

a radiographic examination of the lymphatic vessels after injection of contrast material.

Question 20

Answer 24

the procedure in which ionizing radiation with computer assistance passes through the patient and shows the internal body structures in crosssectional views

Question 25

CT scan/CAT scan

Answer 25

Another term for Computed tomography.

Question 26

Tomography

Answer 26

a recording of the internal body structures at predetermined planes that produces three-dimensional images.

Question 27

Magnetic resonance imaging

Answer 27

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.

Question 28

Fluoroscopy

Answer 28

the procedure used to visually examine internal body structures in motion using radiation to project images onto a fluorescent screen as light

Question 29

Luminous

Answer 29

giving off a soft light

Question 30

ultrasound/ultrasonography

Answer 30

the imaging of internal body structures by recording echoes of high frequency sound waves.

Question 31

sonogram

Answer 31

ultrasound image that shows the internal body structures by recording echoes of pulses of sound waves above the range of human hearing.
