ARTICLE HIGHLIGHTS
Research background
The criteria for pneumothorax using ultrasound is usually based on qualitative methodologies.
Research motivation
Tissue Doppler imaging (TDI) technology might discriminate pneumothorax by quantifying pleural line movement. Based on that, pneumothorax might be diagnosed in an objective way.
Research objectives
TDI can quantify pleural line movement while diagnosing pneumothorax.
Research methods
Forty-five patients with unilateral pneumothorax were recruited. The pneumothorax side and contralateral normal lung side were then compared using several indices extracted from TDI, such as peak pleural line velocity (PVmax), peak chest wall tissue velocity (CVmax), peak pleural line strain value (PSmax), peak chest wall tissue strain value, PVmax/CVmax, and PSmax/peak chest wall tissue strain value. Receiver operating characteristic analysis was used to evaluate the performance of these quantitative assessments for pneumothorax diagnosis.
Research results
PVmax, PSmax, PVmax/CVmax, PSmax/peak chest wall tissue strain value obtained on the pneumothorax side were lower than those on the non-pneumothorax side. The PVmax/CVmax was the best index for the detection of pneumothorax with an area under receiver operating characteristic curve of 0.99.
Research conclusions
Therefore, we concluded that TDI is an effective tool for the diagnosis of pneumothorax.
Research perspectives
Further research is required to validate our findings in suspected cases.
