Abstract		Purpose: To determine the difference between scattered radiation emitted to testes in anterior (AP) and posterior (PA) projection of sacroiliac joint imaging in conventional radiography, with and without scrotum shield. Methods: The entrance skin dose (ESO) and the dose received by the testicles was measured on the phantom using termoluminiscent dosimeters (TLO). The optimisation was determined according to the European guidelines on quality criteria for diagnostic radiographic images, considering the quality of the image and the dose area product (OAP) measurement. Results: According to the DAP measurements we discovered that the dose received by the phantom in the same exposure conditions in PA is lower than in the AP projections (p~O,009). However, there were no statistically significant differences in the image quality (p~O,483). The dose received by patient's testicles in the PA projection in SIJ imaging is 94% lower than the dose received in the AP projection. No statistica/ly significant differences were determined between the dose received by the testicles in measurements with and without a scrotum shield in AP (p~O,559; p~O,058). Conclusion: We can conclude that it is better to use the PA projection in SIJ imaging, because the dose received by male testicles in significantly lower than the dose received in the AP projection. The use of the classical protection used in the body parts outside the primary x-ray beam is not highly relevant for the reduction of the received dose in AP.
