Summary

Fibered confocal fluorescence microscopy (FCFM) (CellvizioR Lung, MaunaKea Technologies, France) could potentially provide diagnostic information on fibrosis and inflammation of the distal air spaces associated with diffuse parenchymal lung diseases without the need for lung biopsies, thereby fulfilling the gap in the investigators current medical practice of a minimally invasive procedures with few complications and a high diagnostic fidelity.

In patients scheduled for bronchoscopy as part of regular clinical care/diagnostic workup, the investigators will offer the patient concurrent FCFM imaging to be performed during the bronchoscopic procedure. The investigators aim to identify and catalogue distinct and discriminating features seen on images obtained from fibered confocal fluorescence microscopy in this group of patients, and to correlate these findings with specific high resolution computed tomography (HRCT) features and pathological findings if available. Eventually the investigators hope to create diagnostic criteria for fibered confocal fluorescence microscopy image interpretation of specific diffuse parenchymal lung disease entities.

Conditions

  • Diffuse Parenchymal Lung Diseases

Interventions

DEVICE

confocal microscopy

During bronchoscopy, one side of the bronchial tree will be examined (either right or left) and targeted based on pre-procedure HRCT/CT scan findings. A 1.4mm diameter Alveoflex Confocal MiniprobeTM (MaunaKea Technologies, France) will be deployed down the working channel of the standard bronchoscope and advanced distally into the alveoli. Images are acquired by gentle contact providing real-time imaging and microstructural detail of the alveolus which will be continuously recorded during the procedure and stored for further morphometric and cellular analyses. Up to 10 bronchoalveolar areas will be observed and the location of the corresponding lung segment will be registered according to the international bronchial nomenclature.
