Objective To compare the diagnostic value of single and dual phase of enhanced CT in thyroid nodules,and explore the best scanning scheme.Methods A total of 171 nodules in 153 patients were included from January 2020 to June 2022 according to inclusion and exclusion criteria.Image sequence with a delay of 50 seconds was taken for diagnosis in the group of single phase of enhanced CT,then image sequences with a delay of 25 and 50 seconds were taken for diagnosis in the group of dual phase of enhanced CT.Diagnostic accuracy of benign and malignant thyroid nodules,characteristics of thyroid nodules,positive lymph node and enhanced CT features of thyroid nodules in two scanning schemes were the main evaluation indicators.Results There was no statistical significance in diagnostic accuracy of benign and malignant thyroid nodules between single and dual phase of enhanced CT.There was no statistical significance in edge,morphology,capsule,density,calcification and lymph node of thyroid nodules between two scanning scheme.There was no statistical significance in different densities of benign and malignant thyroid nodules between two scanning scheme.There was no statistical significance in enhancement mode of benign and malignant thyroid nodules in dual phase of enhanced CT.Conclusion There is no significant difference in the diagnostic value of single and dual phase of enhanced CT in thyroid nodules,and single phase of enhanced CT would be more suitable for clinical promotion and application by its lower radiation dose.
