CAMRT Radiographic Procedures: Skeletal System Questions and Answers 2

Question 1

For an AP shoulder, how should the arm be positioned to show the greater tuberosity in profile?

Accepted Answer

External rotation with hand supinated and epicondyles parallel to detector

Answer

External rotation places the greater tuberosity in lateral profile.

Question 2

What is the Mortise view of the ankle and how is it positioned?

Accepted Answer

Demonstrates ankle mortise joint uniformly open; internally rotate 15-20 degrees

Answer

Internal rotation 15-20 degrees places the intermalleolar line parallel to the detector.

Question 3

What are the key positioning elements for an AP pelvis radiograph?

Accepted Answer

Centre between ASIS and symphysis pubis; feet internally rotated 15-20 degrees; verify symmetric ASIS positioning

Answer

Internal foot rotation compensates for femoral neck anteversion, showing necks in full length.

Question 4

What are the Ottawa Ankle Rules?

Accepted Answer

Clinical decision rules determining whether ankle radiographs are needed based on physical findings

Answer

Validated rules that reduce unnecessary ankle imaging by 30-40%.

Question 5

What projections constitute a standard knee series?

Accepted Answer

AP, lateral, and obliques showing joint space, patella, and tibial plateaus respectively

Answer

Multiple projections demonstrate different structures without superimposition.
