X-ray translucency of the lungs changes depending on inspired volume. In this study, the usefulness of measuring changes in pixel value on dynamic chest radiographs was assessed in comparison with count of radioactive isotope. In 12 abnormal subjects, there was a good correlation between them (r=0.77) . In eight normal controls, the changes in average pixel value measured in lung unit were almost equal in the right and left lungs, which was consistent with normal respiratory physiology. The results indicated that ventilation performance could be evaluated based on the changes in pixel value on dynamic chest radiographs.
