1. Optical coherence tomography imaging of preneoplastic lung lesion

    Although autofluorescence bronchoscopy improves the detection rate of high grade dysplasia and carcinoma in-situ compares to white-light examination, the natural history of preneoplastic bronchial lesions is still poorly understood because the biopsy procedure for histological confirmation can mechanically remove these small lesions. The lack of accurate information regarding the spontaneous progression and regression rates of preneoplastic lesions make if difficult to assess the effect of chemoprevention agents. It is therefore important to develop non-biopsy methods that can characterize preneoplastic lesions in the bronchial epithelium. Optical coherence tomography (OCT) is an optical imaging method that can visualize cellular and extra-cellular structures ...
