| Popis: | INTRODUCTION:Positioning relative to the lateral automatic exposure control (AEC) chambers (cranial/caudal orientation) optimises dose and image quality in pelvic radiography. In the cranial orientation introducing gonad shielding (GS) in females may increase radiation dose. The aim of this study was to fully optimise the combination of pelvis orientation and use of GS in both male and females. METHODS:An anthropomorphic pelvis phantom was exposed, with dose area product (DAP) recorded, in both orientations without GS and four conditions with GS: cranial orientation (female/male), caudal orientation (female/male). A 4 cm × 4 cm grid incorporating thirteen positions for the GS resulted in 52 experimental settings. Blind image quality assessment, utilising a modified scale, was undertaken by two experienced observers. RESULTS:Comparing no GS (caudal orientation) to female GS, no significant change in DAP was seen (3.97 v 4.03 dGy*cm2; Mann-Whitney p = 0.060). Comparing no GS (cranial orientation) to male GS no significant change in DAP was seen (8.66 v 8.77 dGy*cm2; Mann-Whitney; p = 0.210). DAP increased significantly with introduction of female GS in the cranial orientation (23%: 8.66 v 10.65 dGy*cm2, Mann-Whitney; p |
