Declaration:
I, R. K. Mouj, declare that the material presented in this CXR PA Expiration View reporting module has been prepared solely for educational and academic purposes. Any radiographic descriptions, interpretations, observations, classifications, or example findings provided are illustrative in nature and should not be considered a substitute for professional medical diagnosis. The PA Expiration Chest View is commonly utilized for evaluation of subtle pneumothorax, air trapping, diaphragmatic motion abnormalities, and selected obstructive pulmonary conditions which may not be adequately visualized on routine inspiratory chest radiographs. Clinical correlation, patient history, laboratory investigations, and further imaging studies such as HRCT / CT Thorax may be necessary for accurate diagnosis and management decisions. All chest radiographs should be interpreted by qualified healthcare professionals within the appropriate clinical context.
