Abstract:
Objective:To investigate the application of the parameters of multimodal ultrasound elastography in differential diagnosis for thyroid nodules of patients with diffuse thyroid lesions.Methods:A total of 103 patients with diffuse thyroid lesions who underwent treatment at Affiliated Baoji Hospital of Xi′an Medical University from January 2023 to January 2024 were retrospectively selected,whose thyroid nodules were confirmed by fine needle aspiration biopsy or surgical pathology.They were grouped according to the benign or malignant nodules.56 patients with benign nodules were included in the benign nodule group,while the other 47 patients were included in the malignant nodule group.All patients were examined by conventional ultrasound and multimodal ultrasound elastography,and the relevant parameters were recorded to compare the differences between the two groups.The value of each indicator in diagnosing benign and malignant thyroid nodules was investigated.Results:There were no statistically significant differences between the benign and malignant nodule groups in terms of gender,length diameter of nodule,nodule location,functional abnormalities of thyroid,exposure history of radiation,and the presence of acoustic halos(P＞0.05),the age of patients in the malignant nodule group was lower than that of the benign nodule group(t=-3.121,P＜0.05),and the percentage of nodules with blood flow(14.89%),the percentage of aspect ratio＜1(74.47%),and the percentage of nodules with clear boundary(27.66%)in the malignant nodule group were all lower than those of the benign nodule group,with statistically significant differences(x2=25.634,5.112,12.465,P＜0.05).The ratio of lymphatic metastasis(27.66%)and that of calcification(65.96%)in the malignant nodule group were lower than those in the benign nodule group,and the differences were all statistically significant(x2=11.917,9.350,P＜0.05).The ratios of centripetal enhancement(76.60%),inhomogeneous enhancement(68.09%),low/equal enhancement(87.23%),early obvious discharge(63.83%),unclear boundary after enhancement(91.49%),and fast discharge(59.57%)in the malignant nodule group were higher than that of the benign nodule group,and the differences were statistically significant(x2=33.409,26.695,9.079,12.853,17.798,12.649,P＜0.05),respectively.The intensity and time to peak of the malignant nodule group were respectively lower and long than these of the benign nodule group,and the differences were statistically significant(t=-12.381,4.958,P＜0.05).However,the mean passage time of the two groups was not statistically significant(P＞0.05).The maximum value,minimum value and mean value of Young's modulus,the maximum value of vertical section,mean value of vertical section,maximum value of cross section,mean value of cross section in the malignant nodule group were all higher than those in the benign nodule group,and the differences were statistically significant(t=13.997,9.100,12.191,7.616,6.310,4.679,5.355,P＜0.05).The result of receiver operating characteristic(ROC)curve analysis indicated that both ultrasonography parameters and shear wave elastography(SWE)parameters had higher diagnostic value for the benign and malignant nature of thyroid nodules in patients.The area under curve(AUC)values of intensity to peak,time to peak,and the maximum value,minimum value and mean value of Young's modulus,and the maximum value of vertical section,mean value of vertical section,maximum value of cross section,mean value of cross section were respectively 0.976,0.759,0.974,0.837,0.989,0.872,0.805,0.732 and 0.749.Conclusion:Multimodal ultrasound elastography parameters has significant application value in differential diagnosis for thyroid nodules in patients with diffuse thyroid lesions.In these parameters,the diagnostic AUC values of intensity to peak,time to peak,and the maximum value and mean value of Young's modulus are higher for malignant thyroid nodules of patients,which have higher diagnostic efficiency.It can effectively help clinical doctor to accurately identify the benign and malignant nodules for patients with diffuse thyroid lesions.
