Deoxygenated hemoglobin distribution in several mice.

From top down: Pre-, during, and 24 hours post-ischemia MSOT images for three MCAO mice (left to right) with corresponding H&E stained cryosections for each mouse (bottom; per mouse). MSOT: multispectral data for deoxygenated hemoglobin are presented in blue. Compared with the pre-ischemia situation, images taken during and 24 h post ischemia show clear asymmetry in the vicinity of the infarcted regions, as also apparent in the corresponding histological sections.
