ROI-averaged percentage of black pixels, and Hb, HbO2, HbT and sO2 signals, for CALR tumours (n = 4) imaged over 75 min, during air-breathing. Error bars represent the standard deviation over 3 adjacent central tumour slices (ROIs), 1 mm apart. Solid lines represent a linear regression fitted to the data.
