Fig. 7. Ex vivo MSOT imaging of selected organs. (a) MSOT imaging of liver, kidney, muscle and blood of mice at 1 h post intravenous injection of dark porphyrin 3-Zn (150 μL, 100 μM, n = 3) or PBS (n = 3); MSOT images were unmixed for deoxygenated hemoglobin (blue), oxygenated hemoglobin (red) and dark porphyrin (green). (b) Bar graph that compares the detected mean optoacoustic signal of 3-Zn (unmixed) between mice injected with 3-Zn and the control (PBS).
