In adult patients, when would gonad shielding be used during a non-trauma pelvis X-ray?

Gonad shielding is used to reduce radiation dose to the reproductive organs without compromising the diagnostic quality of the image. In an adult non-trauma pelvis radiograph, the shield should be applied only when it can be placed so that it does not obscure the anatomy or affect the exposure, and when it adds to dose reduction without harming image quality. For the first pelvis X-ray, obtaining a complete and clear image is essential, so shielding is typically not used. If additional non-trauma pelvis images are needed, shielding can be used provided it can be positioned outside the primary beam and will not degrade the study. That balance—protecting the gonads on subsequent exams while preserving image quality on the initial exam—explains why shielding is indicated for non-trauma patients unless it’s their first pelvis study.
