Abstract

The thyroid gland is one of the most susceptible organs to radiation-induced cancer with children being at the highest risk. The aim of this study was to compare if there is a difference in radiation dose to the thyroid when performing an anteroposterior (AP) oblique scapular Y position vs posteroanterior (PA) oblique scapular Y position of the shoulder which is a common diagnostic projection used in a shoulder series. All variables, with the exception of positioning, remained constant with findings that suggest there is a difference in the average dose to the thyroid in the scapular Y views with a 39.19% increase in dose to the thyroid when performing the PA oblique scapular Y position over the AP oblique scapular Y position. There is also a significant difference in magnification of the image when utilizing an AP oblique scapular Y position vs. PA oblique scapular Y position which can affect image sharpness.
