Abstract

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 B and B for the right lung and B and B 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 B 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.
