Overview
The goal of this study is to investigate the ability of two-photon fluorescence microscopy to evaluate dermatologic biopsies. The main questions it aims to answer are:
• How well do two-photon fluorescence images of biopsies taken in a clinic and evaluated by a pathologist agree with conventional histology?
Description
This study will image biopsy specimens using two-photon fluorescence microscopy (TPFM) and then assess how well the images predict the eventual clinical diagnosis using both an expert pathologist and a machine learning model. Because two-photon images can be acquired from small biopsy specimens within minutes of excision, they could potentially be used to immediately diagnose patients, but the accuracy of TPFM for various skin conditions is unknown.
Individual biopsy specimens in a clinic lab will be imaged using TPFM. Following histological processing and patient treatment, resulting histology slides will be scanned for comparison. Images of the histology slides will be read by a pathologist to establish a gold-standard diagnosis and the official diagnosis will be recorded. TPFM images will be evaluated by a pathologist and concordance with the gold-standard determined.
