Abstract

We present 3D intracellular motility imaging in MCD-diet induced non-alcoholic fatty liver disease (NAFLD) model by OCT-based dynamics imaging method, logarithmic intensity variance (LIV). LIV imaging visualizes the label-free intracellular activity. A 1-week and 2-week NAFLD model were investigated. In 1-week NAFLD, formation of large number of highly dynamic small particles at the beneath of the tissue surface were observed in LIV volume rendering image. In 2-week NAFLD model, a thin high LIV layer signal appeared in cross-sectional LIV image just beneath the tissue surface. The LIV projection and volume rendering images also reveal several discontinuous vessel-like structures.
