Core Tip

Core Tip: This study used tissue Doppler to quantify the movement of the pleural line for the diagnosis of pneumothorax in patients with unilateral pneumothorax. Various quantitative variables of the pneumothorax side were all lower than that of the non-pneumothorax side. Peak pleural line velocity/peak chest wall tissue velocity was the best variable to diagnose pneumothorax (area under receiver operating characteristic curve, 0.99). Tissue Doppler quantitative technique is an effective tool for the diagnosis of pneumothorax.
