Question 2
An AP oblique sacroiliac joint projection (RPO position) with poor positioning demonstrates a closed sacroiliac joint, the superior and inferior sacral alae without superimposition, and the lat-eral sacral ala superimposed over the iliac tuberosity.
How was the positioning setup mispositioned for such a projection to be obtained?
a. The pelvis was insufficiently rotated.
b. The pelvis was overrotated.
c. The central ray was not angled.
d. The central ray was centered too medially.
