Example in vivo quad-wavelength ratiometric PAI of a tumor. Each PA functional image in pseudo-color is superimposed on the gray-scale US image. The tumor area is marked by the dashed line in each image. a Quantitative PA pH images at different time points after SNARF-PAA NP injection. Scale bar, 2 mm. b PA images showing the distributions of SNARF-PAA NPs at different time points after injection. c PA image showing the spatially distributed hemoglobin oxygen saturation (sO2) in the tumor area at 75 min after injection. d PA image showing the spatially distributed total hemoglobin concentration (THb) in the tumor area at 75 min after injection
