Abstract
Background/Objects: The purpose of this study is to compare a representative position and two positions what are used clinically at Chest PA examination. Methods/Statistical Analysis: The first position is generally known for minimizing overlap of lung fields and scapulae, and the other 2 positions are mainly used in actual clinics. 3 Radiologic technologists with an average of 7 years' experienced reviewed the images. The overlapping area was measured by connecting the overlapping part of the lung field and the scapula in the radiograph with dots and lines. Findings: We compared the incidence of overlap of scapulae and lung fields depending on sex and age. There were no statistically significant differences between males and females in CP (p>0.05). However, in IRP and HP, there were meaningful differences in the incidence of overlap depending on sex (p0.05). CP showed the least overlapping area followed by HP and IRP. Regarding the ratio of overlapping area, CP had the highest ratio and IRP had the least ratio, but this difference was not statistically meaningful according to Kruskal-Wallis H examination. For reference, a value closer to 1 in this test indicates less of an overlap between the scapula and lung field. Therefore, a position with a value closer to 1 is more useful in separating the scapula and the lung field when conducting Chest PA. Applications/Improvement: The research revealed that both positions are useful in minimizing the overlap between the lung field and scapula.
