C) ASIS and the crest of ilium. 
D) ASIS and the symphysis pubis.

Question 14

A) Repeat both the AP and lateral projections. 
B) Repeat the AP projection only. 
C) Ask another technologist for his or her opinion. 
D) Ask the radiologist if he or she wants the AP projection repeated.

Accepted Answer

A) Ilium 
B) Ischium 
C) Pubis 
D) Sacrum
