DIAGNOSTICS Flashcards
(44 cards)
What imaging method is a compiled
series of X-rays?
CT
A computerized body scanner that
shows us cross-section views of the
body to see bone and tissue is know as
a:
CT scan
Noninvasive technique that produces
images of internal soft tissues through
the use of magnets and radio waves.
MRI
why does bone appear white on X rays?
the X-rays are absorbed by the bone
This medical imagery uses X-ray technology to produce a 3D image
Computed Tomography (CT)
This imaging technique uses sound waves to bounce off tissues and reflect back to a transducer
Ultrasound
This is the most common form of medical imaging. It uses high-energy radiation to
penetrate skin and tissues, but not bone.
A. X-rays
B. Magnetic Resonance Imaging (MRI)
C. Positron Emission Tomography (PET)
D. Ultrasound
A
Bone appears white on X-rays because the X-rays :
A. Excite the atoms in bone so they glow white
B. Cause a chemical reaction in bone that make it glow white
C. Are reflected off the bone
D. Are absorbed by the bone
D
This medical imaging technology Uses X-rays to produce a 3-D image.
A. Radiography - X rays
B. Ultrasound
C. Computed Tomography (CT)
D. Magnetic Resonance Imaging (MRI)
C
This imaging technique uses sound waves to bounce off tissues and reflect back to a
transducer.

D
This is an image produced by using ultrasound technology.
A. Echocardiogram
B. Sonogram
C. Angiogram
D. Radiograph
B
A middle-aged woman comes into the emergency room complaining of stroke-like
symptoms. She has a history of heart problems and high blood pressure so the doctor
thinks there may be a blood clot blocking one of her carotid arteries that supplies
blood to her brain. What type of scan would be the most helpful in diagnosing her
condition?
A. MRI
B. CT scan
C. Fluoroscopy
D. PET scan
D
A 20 year old man has blood in his stool, abdomen pain, and diarrhea. His doctor
wonders it he has inflammatory bowel disease. Which kind of diagnostic imaging Technology should the doctor use first to test his theory?
A. PET scan of the abdominal area
B. Colonoscopy
C. MRI three-dimensional reconstruction of his colon
D. Ultrasound or his abdomen
B
problem with using MRI as a medical imaging technology Is:
A. It doesn’t take images of the internal structures and function of the body
B. It uses a large amount of radiation
C. It cannot be used to observe changes in brain activity in a living person
D. If costs between 1 and 3 million dollars for each machine
D
A patient is given barium before getting an x-ray. What is the purpose of drinking the
bariums
A. To stop the contents of their stomach from blurring the X-rays
B. To allow their stomach and intestines to be X-rayed
C. To protect their stomach trom the radiation
D. It is safer to drink before X-ray exposure than water
B
Why is ultrasound used to see a fetus in the womb rather than a different imaging
technique
A. A fetus cannot hear normal sound
B. It poses very little risk to the fetus
C. It doesn’t require any training to do
D. Ultrasound helps the baby develop
B
Which scan involves the injection ot radioactive isotopes?
A. CT scan
B. CAT scan
C. PET scan
D. MRI SCan
