Which projection is preferred in scoliosis imaging to minimize breast dose?

Explanation:
PA projection minimizes breast dose because the x-ray beam enters from the posterior side and exits anteriorly, placing the breast tissue farther from the primary beam and reducing both entrance skin dose and scatter reaching the breasts. In contrast, an AP view places the breasts closer to the x-ray source and within the primary beam, increasing their radiation exposure. Lateral or oblique projections still expose breast tissue and do not offer the same dose reduction as the PA view in scoliosis imaging.
