Study on the Clinical Value of Dual Source CT Dual Energy Imaging Technology in Differential Diagnosis of Benign and Malignant Thyroid Nodules
Objective To analyze the value of dual-source CT dual-energy imaging in the diagnosis of benign and malignant thyroid nodules.Methods 106 thyroid nodules patients were retrospectively selected.The case collection time was from January 2022 to May 2023,and the collection place was our hospital.The pathological results were statistically analyzed.The CT characteristics,dual source CT dual energy quantitative parameters of thyroid nodules benign and malignant were analyzed,ROC curve was drawn to analyze the diagnostic value of CT features and dual-source CT dual-energy quantitative parameters in benign and malignant thyroid nodules.Results Among 106 patients with thyroid nodules,52 were malignant nodules and 54 benign nodules.The fuzzy margin and irregular shape in malignant nodule were higher than benign nodule,the IC,NIC and λHU in arterial venous phase were lower than benign nodule(P＜0.05).ROC showed AUC value of boundary,shape,IC,NIC and λHU in arterial phase was 0.948,which was higher than AUC value of boundary,shape,IC,NIC and λHU in arterial phase(0.726、0.686、0.761、0.789、0.782,P＜0.05).Conclusion CT characterization and combined detection of dual energy quantitative parameters of dual source CT are more advantageous in the diagnosis of benign and malignant thyroid nodules.
