Abstract
PURPOSE: Identification of abnormal lung expansion by measurment of pleural elastance is useful in evaluating patients with malignant effusion, suspected trapped lung, and post-thoracentesis pneumothorax. We sought to identify chest radiographic findings that would predict abnormal pleural elastance.
METHODS: In a blinded fashion, we reviewed and scored the radiographs of patients who had pleural manometry as well as pre and post-thoracentesis radiographs. Effusions were scored on a scale of 1-4
