Which methods are recommended to reduce breast radiation dose during scoliosis examinations?

• A. PA Position And Lateral Position
• B. PA Position And With Breast Shields
• C. Lateral Position And With Breast Shields
• D. PA Position, Lateral Position, And With Breast Shields

Answer: (B)

Using a PA projection with breast shielding provides the greatest reduction in breast dose during scoliosis radiography. The PA setup places the breasts farther from the primary beam, which lowers the entrance dose to breast tissue compared with an AP orientation. Adding a breast shield further decreases dose by blocking scatter and superficial exposure. A lateral view, while sometimes necessary for spinal assessment, tends to increase breast exposure because the beam path goes closer to or through the breast on the near side, adding additional radiation. Therefore, the combination of a PA projection and breast shielding offers the best balance of protecting breast tissue while still capturing the necessary spinal images.
