Background: Although the utility of virtual bronchoscopy has been reported, the software for virtual bronchoscopy has not been popular because of the high cost. OsiriX is a reasonably priced software that is available to reconstruct virtual endoscopic images. Herein, we present the ability of OsiriX to enable virtual bronchoscopy.
Methods: Computed tomography of the chest was performed using a 16-row multidetector. Data in 2 mm slices from one lung were obtained from 10 patients with a lung nodule. Virtual bronchoscopic images were established by OsiriX version 5.5 (32-bit). To examine the ability to visualize small bronchi, we tried to visualize the distal bronchus if possible. We selected B1a and B10c for the right lung and B1+2a and B10c for the left lung. In addition, to predict whether a pathologic diagnosis can successfully be made by transbronchial lung biopsy, we reconstructed virtual bronchoscopic images toward the lung nodule.
Results: Bronchoscopic images were successfully reconstructed for all patients. The third to the seventh bronchi were visualized except in one patient whose right B10 was occluded by a tumor. In all patients, the virtual bronchoscopic path reached the lung nodule, and 5 lung nodules were successfully diagnosed by transbronchial biopsy.
Conclusions: OsiriX is practicable for virtual bronchoscopy at a low cost.
