The DSCT quantitative parameters and Haematoxylin-eosin stain in a 30-year-old women with thyroid papillary carcinoma. a Axial non-contrast CT image shows micro-calcification in micro-nodule of thyroid right lobe. b-d CT value of arterial phase 40 keV, 70 keV and 100 keV monochromatic image is 301.1 HU, 117.3HU, 78.6HU, respectively. e Arterial phase NIC is 0.28. f Arterial phase NZeff is 0.79. g Arterial phase λHu of the energy curve is 3.71 HU/keV. h-j CT value of venous phase phase 40 keV, 70 keV and 100 keV monochromatic image is 299.1 HU, 118.4HU, 79.4HU, respectively. k Photomicrograph confirmed the pathological finding of the nodule as papillary thyroid carcinoma.(Hematoxylin-eosin stain; original magnification, 40.) l Venous phase NIC is 0.68. m Venous phase NZeff is 0.93. n Venous phase λHu of the energy curve is 3.66 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
