We have combined hyperspectral imaging with spectral domain optical coherence tomography (SDOCT) to noninvasively image changes in hemoglobin saturation, blood flow, microvessel morphology, and sheer rate on the vessel wall with tumor growth. Changes in these hemodynamic variables were measured over 24 h in dorsal skin fold window chamber tumors. There was a strong correlation between volumetric flow and hemoglobin saturation (rho=0.89, p=9x10(-6), N=15) and a moderate correlation between shear rate on the vessel wall and hemoglobin saturation (rho=0.56, p=0.03, N=15).
我们将高光谱成像与光谱域光学相干断层扫描(SDOCT)相结合,以无创方式成像随着肿瘤生长,血红蛋白饱和度、血流、微血管形态以及血管壁上的切变率的变化。在背部皮肤褶皱窗口室肿瘤中,对这些血液动力学变量的变化进行了24小时的测量。体积流量与血红蛋白饱和度之间存在强相关性(rho = 0.89,p = 9×10⁻⁶,N = 15),血管壁上的切变率与血红蛋白饱和度之间存在中度相关性(rho = 0.56,p = 0.03,N = 15)。
