[Imaging technics in bronchology].

Bronchoscopic imaging and diagnostics are tightly connected with radiological and pathological techniques. While computer tomography (virtual bronchoscopy) makes possible to mimic a realistic endobronchial situation, autofluorescent bronchoscopy holds significant potential to discover precancerous lesions not identifiable by standard bronchoscopy. Endoscopic ultrasound and fluoroscopy can be applied in order to obtain images and tissue samples from the extrabronchial areas. Electromagnetic navigation during flexible bronchoscopy, a novel technology that facilitates approaching peripheral lung lesions, involves creating an electromagnetic field around the thorax and localizing an endoscopic tool using a microsensor overlaid upon previously acquired CT images. In conclusion, parallel use of invasive and non-invasive imaging has the potential for considerable improvements in the diagnostic possibilities of routine bronchoscopic procedures.
