To evaluate the use of dual-energy spectral computed tomographic (CT) quantitative parameters compared with the use of conventional CT imaging features for preoperative diagnosis of metastasis to the cervical lymph nodes in patients with papillary thyroid cancer. ⋯ Quantitative assessment with gemstone spectral imaging quantitative parameters showed higher accuracy than qualitative assessment of conventional CT imaging features for preoperative diagnosis of metastatic cervical lymph nodes in patients with papillary thyroid cancer.
