ANSWERS GUARANTEED TO PASS
◉ To properly visualize the joint spaces w/ the AP projection of the
foot. the CR must be:
parallel to the longitudinal arch
perpendicular to the metatarsal
perpendicular to the longitudinal arch
parallel to the metatarsals.
Answer: perpendicular to the metatarsals
◉ What CR angulation is required for the AP oblique projection of
the foot?
CR perpendicular
10 degrees
15-20 degrees
5-7 degrees.
Answer: CR perpendicular
◉ A correctly positioned AP medial OBL foot projection will
demonstrate
,3rd-5th metatarsal free of superimposition
1st-5th metatarsal s free of superimposition
1st-2nd cunieform joint space open
cr is centered to mid shaft of 3rd metatarsal.
Answer: 3rd-5th metatarsal free of superimposition
◉ A lateral knee radiograph that is over rotated toward the IR can be
recognized by which of the following?
The fibular head will appear more superimposed by the tibia than a
true lateral
The fibular head will appear less superimposed by the tibia than a
true lateral.
Answer: The fibular head will appear less superimposed by the tibia
than a true lateral
◉ You are taking an AP projection of the tibia and fibula on an adult
and need to ensure that both joints are included, what you should
do?
Increase SID to 60 inches
Use the bucky
Turn the IR diagonally.
Answer: Turn the IR diagonally
, ◉ How much is the foot dorsiflexed with the tangential sesamoid
bone projection if the CR remains perpendicular to IR?
15-20 degrees from vertical
no flexion
5-7 degrees from vertical
30-45 degrees from vertical.
Answer: 15-20 degrees from vertical
◉ what CR angulation (if any) is required for an AP projection of the
toes
CR perpendicular to IR
5 degree toward calcaneous
10-15 toward calcaneous
20-25 toward calcareous.
Answer: 10-15 toward calcaneous

should the technologist place on the IR in the unexposed area?
Lead masking
Nothing
The opposite body part for comparison.
Answer: Lead masking
