Diagnosing hemothorax after @entity130 may be aided by @entity341 ( @entity341 ) ultrasound (US). Various prior studies have evaluated @entity341 US using different gold standards. A prospective study of @entity130 @entity1 who underwent computed tomography (CT) scan of the chest, abdomen, or both, was performed. Before CT scan, an US examination was performed specifically to identify free fluid in the thorax. The CT scan findings were used as the gold standard for validation of US results. From July 1998 to June 1999, 142 of 155 @entity1 who underwent US and CT scan for evaluation of @entity130 were included in this study. The CT scan identified 16 cases of hemothorax among these @entity1 . @entity341 US resulted in 2 true-positive, 2 false-positive, 14 false-negative, and 124 true-negative findings. @entity341 US was 12.5% sensitive and 98.4% specific. @entity341 US did not detect small-volume hemothorax identified by CT scan. Future research should focus on further defining the size of hemothorax appreciable with @entity341 US, with increased attention paid to the type of gold standard implemented for its evaluation.
