Comparison of upright inspiratory and expiratory chest radiographs for detecting pneumothoraces

摘要: Expiratory films are regarded as being superior to inspiratory for pneumothorax detection, yet this has not been proved. In the current study, we compared versus expiratory chest radiographs detection.Eighty-five paired and with pneumothoraces 93 pairs without were randomly arranged reviewed independently by three radiologists. A score of 1-5 was assigned each hemithorax (5 = definite pneumothorax, 1 definitely no pneumothorax). Results inspiration expiration using receiver operating characteristic (ROC) analysis.The average area under ROC curves all readers .973 .972 (nonsignificant). McNemar's test an alpha level .05 also yielded significant difference in sensitivity specificity. Four 85 cases scored on readers, ca...
