Using the University Hospital Münster (UKM) hand-held curvilinear system: parameters extracted from multiwavelength PA imaging of invasive carcinoma. In invasive carcinoma (n = 5) significantly increased tumour-control ratios for (A, B, C) Hb, HbO₂ and HbT were found in the tumour centre compared with peritumoural tissue. Likewise was found in the comparison of calculated ratios of Hb and HbT in the tumour margin and peritumoral tissue (A, C). No significant differences could be found for oxygen saturation (D).
