Changes in sO2 and total hemoglobin during and after NIR PIT. (A) Anatomical image (B mode) and temporal change in sO2 for NIR PIT-treated H520 (top row, n = 4) and A431 (bottom row, n = 3) tumors. A darkened color map was observed in A431 tumors after NIR PIT treatment. (B) Plots of sO2 (left) and total hemoglobin (right) in A431 (red) and H520 (black) tumors. Both sO2 and total hemoglobin values dropped in A431 tumors during NIR PIT, while non-significant changes were observed in H520 tumors.
