- Primary Outcome Measures
Name Time Method The diagnostic yield based on histological or cytological findings via transbronchial biopsy or fine needle aspiration
- Secondary Outcome Measures
Name Time Method 1. The improvement rate of Radial EBUS images<br>We classify the positional relation of the R-EBUS probe with the lesion into three groups as follows: a) within, when the probe is located inside the lesion; b) adjacent to, when the probe is located at the periphery of the lesion; c) outside, when the probe is located outside the lesion.<br><br>We set the improvement of the EBUS images as follows: when the EBUS image of 'adjacent to' changed to 'within' or the image of 'invisible' changed to 'adjacent to' or 'within', the EBUS imaging is considered to have improved.<br><br>2. The examination time
