Air trapping in a 57-year-old man with acromegaly who had a RV value of 173% of predicted and a Raw value of 3.47 cm H 2 O/L/s. (a) Inspiratory, transverse, thin-section CT scan obtained through the lower lung zone shows no abnormal findings. (b) Expiratory, transverse, thin-section CT scan obtained through the lower lung zone reveals diffuse air trapping (arrows).
