Fig. 4From: Dual-energy CT quantitative parameters for evaluating Immunohistochemical biomarkers of invasive breast cancerThe dual-energy CT quantitative parameters and immunohistochemical staining in two women with invasive breast cancer. Patient 1 was a 51-year-old woman who was Ki67 high-proliferation, while patient 2 was a 46-year-old woman who was Ki67 low-proliferation. NIC = normalized iodine concentration; nZeff = normalized effective atomic number; λHu = slope of the spectral Hounsfield unit curveBack to article page
