Conditions
Interventions
One day before the procedure,
the bronchoscopist performs image-
reconstruction using computer software,
LungPoint,
to create the 3-
D virtual map to reach the target lesion. For the procedure,
the bronchoscopist controls the movement of bronchoscope under the guidance of program to reach target lesion. R-
EBUS and fluoroscope are applied to confirm target lesion location then the bronchoscopist collects specimens by performing lung biopsy and bronchial brushing. Bronchoalveolar lavage for cytology and
VBN added to routine bronchoscopy,Routine bronchoscopy
