Traditional imaging methods have limitations in the diagnosis of peripheral lung lesions. The aim of this study is to evaluate the diagnostic value of the distance measurement method based on ultrasound image-based inverted electrostrain (rEBUS) combined with thoracoscopic lung biopsy (TBLB) for peripheral lung lesions. A group of patients with peripheral lung lesions were recruited for the study, and rEBUS examination was performed simultaneously during TBLB. Using rEBUS ultrasound images combined with electrostrain information, evaluate the morphological characteristics of peripheral lung lesions and the elastic properties of internal tissues. By comparing with pathological examination results, both rEBUS-D-TBLB and rEBUS-GS-TBLB have a higher positive diagnostic rate for PPL under bronchoscopy. However, rEBUS-D-TBLB is more effective in diagnosing benign PPL with ≥ 3 cm PPL than rEBUS-GS-TBLB. The rEBUS-TBLB combined ranging method has shown high accuracy and sensitivity in diagnosing peripheral lung lesions. Ultrasound images provide clear morphological features of the tumor, while the electrical strain information of rEBUS provides elastic information of the internal tissue of the tumor, further improving the accuracy of diagnosis.
传统成像方法在周围型肺病变的诊断中存在局限性。本研究旨在评估基于超声图像的反向电应变（rEBUS）联合胸腔镜肺活检（TBLB）的距离测量方法对周围型肺病变的诊断价值。招募一组周围型肺病变患者进行研究，并在TBLB期间同时进行rEBUS检查。利用rEBUS超声图像结合电应变信息，评估周围型肺病变的形态特征及内部组织的弹性特性。通过与病理检查结果对比，rEBUS-D-TBLB和rEBUS-GS-TBLB在支气管镜检查下对周围型肺病变（PPL）均有较高的阳性诊断率。然而，对于直径≥3 cm的良性PPL，rEBUS-D-TBLB比rEBUS-GS-TBLB诊断效果更佳。rEBUS-TBLB联合测距方法在诊断周围型肺病变中显示出较高的准确性和敏感性。超声图像提供了肿瘤清晰的形态特征，而rEBUS的电应变信息提供了肿瘤内部组织的弹性信息，进一步提高了诊断准确性。
