ROC curves using ICA/ICv, NICA/NICV, ZeffA/ZeffV and λHUA/λHUV in differentiating metastatic and nonmetastatic lymph nodes in PTC patients with HT (a) and without HT (b). PTC, papillary thyroid cancer; HT, Hashimoto’s thyroiditis; ICA/ICv, iodine concentration in arterial/venous phase; NICA/NICV, normalized ICA/ICv; ZeffA/ZeffV, effective atomic number in arterial/venous phase; λHUA/λHUV, slope of the spectral Hounsfield unit curve in arterial/venous phase; and ROC, receiver operating characteristic
