In this study, the effectiveness of transthoracic ultrasound elastography in the benign and malign distinction of subpleural/pleural solid lesions was investigated.Between July 2015 and December 2016, 33 consecutive patients with subpleural solid lesions detected via computed tomography (CT) of the thorax were identified and prospectively included in this study. The average for each lesion's shear wave velocity (SWV) value was detected, and benign and malignant lesions' SWV values are statistically compared. The CT and pathology results were used as a reference to compare these values. A receiver operating characteristic analysis was used to determine the cutoff value for benign/malignant neoplasms.The 33 patients (10 female, 23 male) included in the study had a mean age of 56.2 +/- 15.40 years (range, 17-84 years), and the mean SWV value of the lesions in 13 (39%) cases evaluated benign after a CT scan, histopathological examination, or both 2.18 +/- 0.49 m/s. The mean SWV value of the lesions which were histopathologically diagnosed as malign in 23 (61%) cases was 3.50 +/- 0.69 m/s. (P < 0.001). When the cutoff value was set as 2.47 m/s for the SVW value, sensitivity and specificity were determined to be 97.7%.The present study has shown that transthoracic ultrasound shear wave elastography can be an effective radiological examination method in the benign and malign differentiation of subpleural lesions and has the potential for use in the routine clinical application of transthoracic ultrasound elastography, a noninvasive method for evaluating the malignancy potentials of such lesions.
