Abstract
Background: To further investigate the differential diagnosis of thyroid nodules using dual-energy computed tomography (DECT) and explore the relationship between DECT parameters and lymph node metastasis in thyroid carcinoma for clinical practice, especially difficult diagnosis by routine imaging examination. Methods: -test, Chi-squared test, and receiver operating characteristic (ROC) curves. Results: (1.185), and their corresponding AUC were 0.729, 0.641 respectively. Conclusions: Base on our study, we think DECT is useful in differentiating malignant from benign thyroid nodules, which has potential value in the indirect prediction of lymph node metastasis in thyroid carcinoma.
