The DSCT quantitative parameters and Haematoxylin-eosin stain in a 38-year-old women with thyroid nodular goiters. a Axial non-contrast CT image shows the micro-nodule of thyroid left lobe. b-d CT value of arterial phase 40 keV, 70 keV and 100 keV monochromatic image is 375.4 HU, 142.3 HU, 85.7 HU, respectively. e Arterial phase NIC is 0.38. f Arterial phase NZeff is 0.83. g Arterial phase λHu of the energy curve is 4.83 HU/keV. h-j CT value of venous phase phase 40 keV, 70 keV and 100 keV monochromatic image is 302.2 HU, 123.5 HU, 81.6 HU, respectively. k Photomicrograph confirmed the pathological finding of the nodule as thyroid nodular goiters.(Hematoxylin-eosin stain; original magnification, 40). l Venous phase NIC is 0.70. m Venous phase NZeff is 0.95. n Venous phase λHu of the energy curve is 3.69 HU/keV. AP arterial phase, VP venous phase, HU CT value, λHU the slope of spectral HU curve, NIC normalized iodine concentration, NZeff normalized effective atomic number, H&E Haematoxylin-eosin
