The Benefits of Narrow Band Imaging Bronchoscopy for the Diagnostics of Lung Tumors - An Analysis of Accuracy in Comparison With White Light Bronchoscopy

Abstract

PURPOSE: NBI (Narrow Band Imaging) is a new technology that enhances the visibility of vessels of the mucosa and differentiation between inflammation and pathological vascularization of tumor. On the basis of morphology and frequency of vascular structures it is possible to view the difference in the changes during malignity and inflammation. Moreover, the method is used for the determination of extension of the tumor. It is possible to detect recurrence of tumor after resection and chemotherapy. The aim of our study is to analyze relative sensitivity (the probability of positive results in subjects suffering from the disease) and the rate of false positive results (the probability of positive results in healthy subjects) during examinations in NBI mode as compared to examinations in WL (white light) mode for the diagnoses of malign tumor and severe dysplasia.
