Navigation-assisted bronchoscopy for ground-glass opacity lesions

We thank Dr. Chaves and colleagues for their interest and comments on our article (1). We have attempted to diagnose ground-glass opacity (GGO)-predominant-type lesions by bronchoscopic biopsy using endobronchial ultrasonography with a guide sheath (EBUS-GS) (1,2). The diagnostic rate of GGO-predominant-type lesions is lower than that of solid-type lesions. One of the reasons for this is that the lesions may not be visible under X-ray fluoroscopy.
