Radial probe endobronchial ultrasound scanning assessing invasive depth of central lesions in tracheobronchial wall.

Patients with central tracheobronchial benign or malignant lesions who have not recieved surgical treatment can be treated by interventional techniques, such as laser, afterloading radiotherapy, cryotherapy, photodynamics treatment, radiofrequency ablation and stenting, etc. The accuracy of the invasive depth of central lesion in tracheobronchial wall plays an important role in making interventional treatment plan. This study used radial probe...
