Multimodal virtual bronchoscopy using PET/CT images.
OBJECTIVE To demonstrate the possibilities, advantages and limitations of virtual bronchoscopy using data sets from positron emission tomography (PET) and computed tomography (CT). MATERIALS AND METHODS Eight consecutive patients with non-small cell lung cancer (NSCLC) underwent PET/CT. PET was performed with a glucose analog, 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (18F-FDG), using a state-...
متن کاملCT virtual bronchoscopy for detecting Wegener granulomatosis.
Summers and colleagues (January 2002)1 showed a beneficial method for detecting central airways involvement in patients with Wegener granulomatosis (WG). Indeed, CT virtual bronchoscopy (VB) has an advantage in visualizing stenosis of the airways over either CT scanning alone or bronchoscopy alone. The investigators applied the method to 11 patients with WG, however, they did not describe any d...
متن کاملHaptic-based navigation for the virtual bronchoscopy ⋆
In order to help in the diagnosis of peripheral lung lesions, this paper presents a virtual bronchoscopy system that allows the navigation within a 3D reconstruction of the tracheobronchial tree using a haptic device whose permitted motions mimics those done with the real bronchoscope, and that is able to feedback forces resulting from contacts with the walls. The system reconstructs the 3D mod...
متن کاملEvaluation of Tracheobronchial Lesions with Virtual Bronchoscopy; Correlation with Fiber Optic Bronchoscopy
The aim of this study was to compare the diagnostic accuracy of 3-D virtual bronchoscopy (VB) with that of Fiber-optic (FB) bronchoscopy in patients who had symptoms of respiratory disorders. Thirty patients underwent VB examination. Thin section helical computerized tomography (CT) image were obtained. The volumetric data was downloaded to a workstation equipped with software for surface shade...
متن کاملAccuracy of virtual bronchoscopy for grading tracheobronchial stenosis: correlation with pulmonary function test and fiberoptic bronchoscopy.
STUDY OBJECTIVES To compare the accuracy of virtual bronchoscopy (VB) with fiberoptic bronchoscopy (FOB) and pulmonary function testing (PFT) for the assessment of tracheal stenosis and bronchial anastomotic stenosis. DESIGN Prospective case series. SETTING Pulmonary institute of major tertiary university-affiliated center. PATIENTS The study group included 10 lung transplant recipients a...
