Abstract

The radiographic examination of the pelvis is a routine procedure in the medical imaging facilities to measure pathological processes like fractures, arthropathy or degenerative disease. However, since X-ray imaging involves the use of ionizing radiation, there is a reasonable possibility of subjecting the sensitive organs of the pelvis, such as the gonads, bladder, rectum and bone marrow to harmful doses of radiation. The current study aimed at determining the levels of organ-specific radiation dose of a cohort of 100 adults who underwent conventional anteroposterior pelvic radiography in three different imaging centers based in Erbil, Iraq. The exposure variables (kVp, mAs, filtration, source-image distance) were measured with a Nomex multimeter and estimates of organ dose were obtained with the PCXMC 2.0 Monte Carlo simulation package. The effective dose rates of the vital organs ranged between 1.04 mSV onto the colon and 3.02 mSV onto the prostate. These findings demonstrate the urgency to unify and align imaging procedures and even guarantee their correspondence to diagnostic reference levels, reducing stochastic threats and preserving diagnostic effectiveness.
