Correct Answers
change
imaging is not needed when there would be no ____________ in treatment from the injury
(no treatment is available, or the patient would not consent to treatment)
X-rays (radiography)
type of imaging that produces a radiograph in the form of an analog image or digital image;
produces ionizing radiation (known to cause cancer) and disrupt cell processes
as low as reasonably achievable
what ALARA stands for; patient should be exposed to the least amount of radiation in order
to get the image needed
intensity of radiation, number and type of images needed, distance from beam, patient
shielding
ALARA considerations for x-rays
attenuation
as x-ray passes through the body, the number of the x-ray photons in the beam decreases as
photons interact with dense tissue
lighter, darker
dense matter shows up as ____________ in an x-ray image, whereas less dense matter shows
up as ____________
contrast agents
, substance that is ingested or injected that makes soft tissue more visible on a radiograph; a
positive contrast medium (because it show up lighter)
negative contrast medium
contrast that shows up darker on an image (ex: air)
positive contrast medium
contrast medium that shows up lighter on an image (ex: injected contrast agent)
