Overview
Peripheral pulmonary lesions are of growing importance in respiratory field. Early detection of lung cancer, tuberculosis and other diseases often needs a bronchoscopic investigation with different types of navigation. Current randomized clinical study is intended to compare three different modalities of navigation in bronchial tree - virtual bronchoscopy (VBN), radial endobronchial ultrasound (EBUS) and combination of both techniques.
Description
Current randomized clinical study is intended to compare three different modalities of navigation in bronchial tree - virtual bronchoscopy, radial EBUS and combination of both techniques. Around 300 patients with incidentally detected peripheral pulmonary lesions will be enrolled in 9 centers among Russia. All patients after obtaining an informed consent will be randomized in 1:1:1 fashion to three study groups depending on type of navigation technique used. All patients will undergone navigational bronchoscopy with rEBUS (group A), VBN (group B) and rEBUS+VBN (group C), data on diagnostic efficacy and safety of each modality of navigation will be analyzed.

- Age > 18 years
- Signed Informed consent form

Exclusion Criteria:
- Unability to undergone navigation bronchoscopy for any reason
