Q1 QUESTION 1 OF 73
sagittal view
CORRECT ANSWER
Divides right/left
Q2 QUESTION 2 OF 73
Coronal view
CORRECT ANSWER
divides front/back
Q3 QUESTION 3 OF 73
axial view
CORRECT ANSWER
divides upper/lower
Q4 QUESTION 4 OF 73
computed tomography (CT)
CORRECT ANSWER
a scanning technique using multiple X-rays to construct three-dimensional images.
•Uses x-ray and a computer
•X-ray rotates around patient inside hole (gantry)
•Body is viewed as a "slice" like a loaf of bread
•Computer creates crosssectional images of body
•Radiation reported as mGy unit
• Proportional to energy in breaking of cell bonds

, Q5 QUESTION 5 OF 73
•Most effective for viewing bone and soft tissues
•Blood vessels
•Shows soft tissues better than x-ray
•Quick & effective = top choice for emergency imaging
CORRECT ANSWER
What does a CT show?
Q6 QUESTION 6 OF 73
MRI (magnetic resonance imaging)
CORRECT ANSWER
•Uses a magnet, radio waves and a computer •Detects different water concentrations in tissues •Body is viewed as a
"slice" like a loaf of bread - 1/4" thick
•Computer creates cross-sectional images of body
• 2D or 3D
can "see" hydrogen nuclei contained in water molecules.
• Hydrogen nuclei have a quantum physics property called "spin" which means they can be 'oriented' in certain ways
• MRI first "irritates" hydrogen nuclei; and then from response detects their presence
Uses magnet to flip the hydrogen nuclei around; out of their normal alignment in the body
• When the nuclei realign into proper position they send out radio signals
• These signals are received by the computer that analyzes and converts them into 2D image of body part being imaged.
Q7 QUESTION 7 OF 73
MRI
CORRECT ANSWER
Generally favored to CT because lack of ionizing radiation
• Only not preferred in situations of MRI contraindication (e.g. Pacemaker), too expensive, time is of the essence, or
extreme claustrophobia
