Radiology Supplement

Question 1

Radiology

Answer 1

the production of images of the body for the diagnosis and treatment of disease
Medical Imaging or Diagnostic Imaging
x-rays, ultrasound, radioisotopes, and magnetic resonance

Question 2

nuclear medicine

Answer 2

part of diagnostic imaging that uses radioactive materials or radioisotopes to create images

Question 3

radiation therapy

Answer 3

a treatment process rather than an imaging process.

Question 4

interventional radiology

Answer 4

part of radiology and involves procedures where imaging is used to help treat the patient, rather than just produce an image.

i.e. when ultrasound is used to place a biopsy needle in a suspected tumor or CT is used to guide a catheter to a blood clot so that a chemical that dissolves the clot can be injected into the correct location.

Question 5

dosimetry

Answer 5

the measuring of radiation exposure

Question 6

film badge

Answer 6

healthcare workers who regularly work around radiation wear a film badge, radiation monitor.

the radiation monitor device is not an actual film badge anymore. different technology is used now but the purpose is still to monitor radiation exposure and the old term is still used.

Question 25

barium enema (BE)

Answer 25

images of the large intestine using barium resulting in barium enema images

Question 26

fluoroscopy

Answer 26

a type of radiography that employs an ongoing stream of x-rays so that a continuous image is produced. allows movement within the body to be watched and recorded

Question 27

CAT

Answer 30

computerized axial tomography

Question 31

CT

Answer 31

computerized tomography

Question 32

computerized axial tomography | computerized tomography

Answer 32

the use of x-rays and a computer to create cross-sectional images of anatomy. most commonly the cross-sectional images at taken of the transverse plane contrast media (barium and iodinated contrast) may be used to enhance the visualization of structures

Question 33

MRI

Answer 33

magnetic resonance imaging

Question 34

magnetic resonance imaging

Answer 34

use of a powerful magnetic field, radio frequencies, and a computer to produce 3D images of anatomy

Question 35

diagnostic medical sonography | ultrasonography

Answer 35

consists of using inaudible, high frequency sound waves that act to produce an image of a tissue. the sound waves travel into the body and then bounce back like an echo

Question 36

echocardiography

Answer 36

a form of sonography which specifically images the contraction and relaxation phases of the heart. used to evaluate how well the heart valves are working

Question 37
