Overview

To use the shear-wave elastography to assist the transthoracic ultrasound-guided aspiration biopsy of peripheral lung tumor 1. To identify the intra-tumor heterogeneity of elasticity 2. To increase the diagnostic yield in ultrasound-guided transthoracic biopsy of subpleural pulmonary tumor
