    In vivo, label-free, three-dimensional quantitative imaging of kidney microcirculation using Doppler optical coherence tomography
    Doppler optical coherence tomography (DOCT) is a functional extension of optical coherence tomography (OCT) and is currently being employed in several clinical arenas to quantify blood flow in vivo. In this study, the objective was to investigate the feasibility of DOCT to image kidney microcirculation, specifically, glomerular blood flow. DOCT is able to capture three-dimensional (3D) data sets consisting of a series of cross-sectional images in real time, which enables label-free and non-destructive quantification of glomerular blood flow. The kidneys of adult, male Munich–Wistar rats were exposed through laparotomy procedure after being anesthetized. Following exposure of the kidney beneath ...
