PATIENT RADIATION DOSE FROM CHEST X-RAY EXAMINATIONS IN THE WEST BANK—PALESTINE

On February 2018, Adnan Lahham, Ahlam Issa and Hussein AL Masri published a new study in Radiation Protection Dosimetry "PATIENT RADIATION DOSE FROM CHEST X-RAY EXAMINATIONS IN THE WEST BANK—PALESTINE"

 The article aimed to evaluate the organ doses and effective doses for patients undergoing chest X-ray radiography in different projections.

The results of this study demonstrated that The absorbed organ doses were calculated for 29 body organs for every patient. The average organ doses were evaluated from all patients in anterior posterior anterior (AP), posterior anterior (PA) and lateral projections. PA and lateral projections in chest radiography account for more than 75%, of chest X-ray examinations. In case of incapacitated patients, AP projection was performed by portable X-ray machine. Calculations of organ and effective doses were conducted while a patient is positioned with arms in PA and AP projections and without arms in lateral projections. The highest average organ dose was 0.56 mGy and received by breasts in LAT projection. Breasts received also the highest dose in AP projection, ~0.56 mGy. While the highest average dose in PA projection was found for lungs, ~0.23 mGy. Relatively high doses were received by spleen in both PA and LAT projections, while heart receives high doses in AP and LAT projections. Skeleton is exposed approximately to the same radiation dose in the all three projections. The organs exposed to the lower doses in all projections of chest X-ray were brain, testicles, urinary bladder and uterus. Figure 1 presents the average organ doses for all surveyed patients.
