The Efficacy of Shear-wave Elastography-guided Aspiration and Biopsy for Diagnosis in Lung Tumor

The Efficacy of Shear-wave Elastography-guided Aspiration and Biopsy for Diagnosis in Lung Tumor: a Randomized Controlled Trial

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

Inclusion criteria:

(1) Patients with radiographic evidence of pulmonary lesions

Exclusion criteria:

1. Age < 20 y/o
2. Patients who cannot hold their breath for 5 seconds
3. Inadequate shear-wave propagation of lung tumor
