Mean MSOT signal intensity for oxyhemoglobin correlates with colitis severity score. Region of intensity measurements acquired for MSOT images were correlated to colitis severity score determined from colonoscopy images. (A) Mean signal intensity of oxyhemoglobin for each group (control, 2 d after ETBF inoculation, and 7 d after ETBF inoculation). ***P < 0.001. (B) Average colitis severity score for each group. ***P < 0.001. Error bars represent SD. (C) Correlation between mean signal intensity of oxyhemoglobin and mean colitis severity score for the 3 mice assessed using both MSOT and colonoscopy at all 3 time points (r = 0.82, P = 0.013). a.u. = arbitrary units.
