Representative images and energy spectrum curves of metastatic lateral lymph nodes in PTC patients with HT (a–d) and without HT (e–h). Metastatic LNs in PTC patients with HT demonstrated lower IC (3.000 vs. 6.300 mg/mL), NIC (0.248 vs. 0.670), Zeff (9.000 vs. 10.200), and λHU (5.924 vs. 11.313) than those in PTC patients without HT in arterial phase. PTC, papillary thyroid cancer; HT, Hashimoto’s thyroiditis; LN, lymph node; IC, iodine concentration; NIC, normalized IC; Zeff, effective atomic number; and λHU, slope of the spectral Hounsfield unit curve
