●● Where is the CR directed on a lateral calcaneus projection?
Lateral MAl
base of the first metacarpal
1 in distal to medial MAL
distal tip/fib joint space
Answer: 1 in distal to medial MAL
●● What CR angle Is required for an AP projection of the knee on a
patient W/ an ASIS to TT measurement of 18 cm
3-5 caudad
3-5 cephalic
perpendicular
10-15 cephalic
Answer: 3-5 ciudad
●● what cr angle should be used for a lateral projection of the knee on a
short wide pelvis patient?
No angle
5 cephalic
,7-10 cephalic
5-19 cephalic
Answer: 7-10 cephalic
●● which projection would best visualize a fibular head fracture?
lateral knee
medial obl knee
PA knee
AP knee
Answer: medial obl knee
●● 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
