title: Visualization of air-trapping area with expiratory CT in hypersensitivity pneumonitis.
abstract: We report a case of summer-type hypersensitivity pneumonitis that demonstrated air-trapping. In this case we used images at inspiratory and expiratory volumetric HRCT, which enabled us to obtain images of the same level at inspiratory and expiratory CT.
