Quantification analysis of pleural line movement for the diagnosis of pneumothorax

Figure 5 Scatter plot of measurements obtained by tissue Doppler imaging. A: Scatter plot of peak pleural line velocity; B: Scatter plot of peak pleural line strain value; C: Scatter plot of peak pleural line velocity/peak chest wall tissue velocity; D: Scatter plot of peak pleural line strain value/peak chest wall tissue strain value. Data are expressed as the median and interquartile range. PV_max: Peak pleural line velocity; CV_max: Peak chest wall tissue velocity; PS_max: Peak pleural line strain value; CS_max: Peak chest wall tissue strain value.
