Abstract：Objective:To explore the diagnostic efficacy of the combined detection of thyroid cancer by color Doppler ultrasound and two-dimensional ultrasound technology.Method:96 patients with suspected thyroid cancer admitted to the First Hospital of Putian City from August 2021 to December 2024 were selected as the research subjects.Color Doppler ultrasound and two-dimensional ultrasound examinations were used.With pathological examination as the gold standard,the efficacy of color Doppler combined with two-dimensional ultrasound in the diagnosis of thyroid cancer was explored,and the ultrasound parameters of the three examinations were compared.Result:Among 96 suspected thyroid cancer patients,81 cases were diagnosed by pathological examination.Among them,70 cases were detected by two-dimensional ultrasound,75 cases by color Doppler ultrasound,and 80 cases were detected by combined examination.The combined examination had higher sensitivity,accuracy and negative predictive value than two-dimensional ultrasound diagnosis,and the difference was statistically significant(P<0.05).The combined examination had higher diagnostic sensitivity,accuracy and negative predictive value than color Doppler ultrasound.The combined examination had higher diagnostic specificity and positive predictive value than two-dimensional ultrasound and color Doppler ultrasound,but the differences were not statistically significant(P>0.05).The detection rates of solid hypoechoic,microcalcification,irregular margins and nodule blood flow within the body by color Doppler ultrasound were all higher than those by two-dimensional ultrasound.The combined examination had higher detection rates of solid hypoechoic,microcalcification,irregular margins and nodule blood flow within the body than two-dimensional ultrasound and color Doppler ultrasound,and the differences were statistically significant(P<0.05).Conclusion:Color Doppler ultrasound combined with two-dimensional ultrasound technology performs well in the diagnosis of thyroid cancer,significantly improving the accuracy,sensitivity and specificity of diagnosis,and providing a strong basis for clinical diagnosis and treatment decisions.
