Only 2 studies have investigated ultrasound elastography for pneumothorax, both in strain elastography, reporting positive results and describing the novel elasto-lung point sign to aid in identifying the lung point. The objectives of this study are to confirm the existence of the elasto-lung point using 2-dimensional shear-wave elastography (2D-SWE), and to evaluate the utility of elastography in pneumothorax cases lacking a detectable lung point.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Prospective single-centre study of 32 consecutive patients with imaging-confirmed pneumothorax. The 2D-SWE measurements were collected from the pneumothorax area and the contralateral lung for comparative analysis. Ultrasound elastography was preferably performed during forced inspiration; when infeasible, measurements were collected during end-expiration or spontaneous breathing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The 2D-SWE measurements were collected primarily during spontaneous breathing (93.8%) and showed no significant differences in elasticity between pneumothorax and healthy lung. The lung point was detected in 14 patients, with the elasto-lung point identified in 13 (93% sensitivity; Cohen\u2019s Kappa\u2009=\u20090.936, P\u2009&amp;lt;\u2009.001). The 2D-SWE did not differentiate pneumothorax from healthy lung in absence of elasto-lung point.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The 2D-SWE is a useful complement to ultrasound for detecting the lung point through visualization of the elasto-lung point.
