To estimate radiation dose and evaluate the additional value of CBCT for bronchoscopy in diagnosing peripheral lung nodules.
Prospective pilot study involving 20 patients
Used thin/ultrathin bronchoscopy, radial-probe endobronchial ultrasound (RP-EBUS), and CBCT
Measured radiation dose and assessed navigational and diagnostic yields.
Median lesion size was 2.1 cm; 60% of lesions showed a bronchus sign
CBCT increased navigation yield from 50% to 75% (P=0.02) and diagnostic yield from 50% to 70% (P=0.04)
Mean radiation exposure ranged from 8.6 to 23 mSv with 55% of patients receiving 1 CBCT scan.
