Assessment
Primary outcomes	The detectability of lesions in three groups according to the number of the stroke movements: the low-number group (20 times), the moderate-number group (25 times), and the high-number group (30 times).
Key secondary outcomes	1)Correlation between the detectability and size of lesions 2)The detectability of lesions of lung cancer and sarcoidosis. 3)The detectability of non-necrotizing granulomas in TBLB and EBUS-TBNA. 4)The rate of contraflow of blood in the EBUS-TBNA procedures
