Which carpal bone can easily be palpated on the anteromedial surface of the wrist?
pisiform
Stress images of the ankle may be ordered to evaluate what pathologic condition?
Inversion/eversion injury
The bony process on the proximal, medial side of the femur is known as:
lesser trochanter
The dorsal surface of the foot refers to the:
top surface
Which of the following bony structures are commonly associated with two small sesamoid bones?
head of the first metatarsal
What position is the first digit in when the palm is pronated and resting on the image receptor (IR)?
oblique
Which term describes a lateral movement away from the body?
abduction
What anatomically important structure is located in the carpal canal?
median nerve
When evaluating a posteroanterior (PA) hand image, the technologist notices that the metacarpophalangeal joints are open, but the interphalangeal joints are not open. What should the technologist do?
repeat the image with the fingers extended and parallel with the image receptor (IR)
What anatomical structure of the humerus is most likely to be affected by trauma?
surgical neck
Where in the hand would it be most common to see two small sesamoid bones?
anterior surface of the head of the first metacarpal
In which projection will the humeral epicondyles form a perpendicular plane to the image receptor (IR)?
lateral elbow
A radiographic image demonstrates the fingernail centered over the distal phalanx, open interphalangeal joints, and equal soft tissue on both sides of the digit. Which radiographic projection is this?
posteroanterior (PA) finger
In which projection of the ankle should the malleoli be equidistant to the image receptor (IR)?
anteroposterior (AP) oblique 15 degree medial rotation
When performing an AP projection of the femur, what is the purpose of internal rotation of the leg?
to compensate for anteversion of the of the proximal femur
