Comparative StudyComparison of upright inspiratory and expiratory chest radiographs for detecting pneumothoraces.
Expiratory films are regarded as being superior to inspiratory films for pneumothorax detection, yet this has not been proved. In the current study, we compared inspiratory versus expiratory chest radiographs for pneumothorax detection. ⋯ Inspiratory and expiratory upright films are equally sensitive for pneumothorax detection. Given the limitations of expiratory films, inspiratory films are recommended as the initial examination of choice for pneumothorax detection.

Comparative StudyDetection and estimation of the volume of pneumothorax using real-time sonography: efficacy determined by receiver operating characteristic analysis.
The purpose of this study was to determine the efficacy of real-time sonography for the detection and estimation of the volume of pneumothorax using receiver operating characteristic (ROC) analysis in 27 patients evaluated by five radiologists using previously described sonographic findings. ⋯ Real time sonography is useful to localize known pneumothorax but cannot be used to exclude the diagnosis. Moreover, sonography has a significant false-positive rate and is of no use in estimating the volume of a pneumothorax.
