We want to compare 2 new systems for obtaining very detailed images of the smallest airways, in the hope that they can be used to provide useful information about lung diseases without the need for invasive tests. Two new systems have been developed for use down the bronchoscope, which provide video imaging of the smallest airways, each system looking at a different aspect of the structure of the airway walls. In principal, this method could provide useful information which may reduce the need for a surgical lung biopsy. We will therefore be assessing the value of the additional information obtained with these two new systems. The purpose of this research project is to gather information using both systems to gain a greater understanding of the tissue characteristics of various diseases without the need for a biopsy.
