When applying gonadal shielding to the ovaries of a patient, the ovarian shields should be placed where?

• A. 2 inches superior to each anterior superior iliac spine.
• B. 1 inch inferior to each anterior inferior iliac spine.
• C. 1 inch medial to each anterior superior iliac spine.
• D. 2 inches medial to each anterior inferior iliac spine.

Answer: (C)

Gonadal shielding aims to protect the ovaries from scatter radiation during pelvic imaging, so the shield must sit directly over the ovarian region without blocking essential anatomy or the primary beam. The ovaries lie near the pelvic walls, just medial to the anterior superior iliac spines. Placing the shield about 1 inch medial to each ASIS positions it over the ovaries, providing protection while keeping the shield out of the primary image area. Options that place the shield higher, lower, or farther from the ASIS can miss the ovaries or unnecessarily obscure anatomy and beam geometry, making protection less effective or compromising image quality.
