text: Comparing sonographic pneumothorax detection (by the absence of parietal-over-visceral lung sliding with "comet tail" artifacts behind it) with the reference standard of chest CT in 169 consecutive trauma patients (ie, 338 lung fields) demonstrated a sensitivity of 47%, specificity of 99%, positive predictive value of 87%, and negative predictive value of 93%; with none of the small pneumothoraces missed by ultrasound requiring drainage during the hospitalization period.
