Measurement of diaphragmatic heights on the reformatted coronal image. (a) At maximal inspiratory image and (b) maximal expiratory image The diaphragmatic heights were taken as the vertical distance in between the line drawn tangent to the highest point of the diaphragm and a parallel line to the lung apex. The diaphragmatic motion is calculated as the difference between inspiration and expiration.
