Background: There are many studies suggesting that the pelvic radiographs taken in posterior-anterior (PA) projection cause far less radiation exposure than anterior-posterior (AP) projection. However, PA projection is rarely used in daily practice due to the concern that the obtained images will not provide radiological standards. Objectives: The aim of the study was to determine whether PA projections meet the radiological criteria of correct positioning as AP projections. Results: The reliability of AP and PA projections was excellent for PRI (Intraclass correlation coefficient [ICC] = 0.66, 95% confidence interval [CI] = 0.90 - 0.98), SIA (ICC = 0.99, 95% CI = 0.90 - 0.98), and PII (ICC = 0.95, 95% CI = 0.90 - 0.98). Conclusion: PA projection instead of AP projection for pelvic radiography has no drawback in terms of acceptability criteria. Considering PA projection is a dose reducing technique requiring no additional equipment, it may be a safer option for children.
