Abstract:
Objective:To analyse the ultrasonic characteristics of conventional ultrasound(US),shear wave elastography(SWE) and 3D-superb microvascular imaging(3D-SMI) in pleomorphic adenoma(PA) and Warthin tumor(WT) of parotid gland,and to investigate the application value of US,SWE and 3D-SMI in PA and WT.Methods:The retrospective analysis was performed in our hospital.From May 2021 to June 2022,80 patients with parotid gland tumor which met the inclusion criteria and were confirmed by surgery and pathology underwent US,SWE and 3D-SMI examinations.To analyse and compare the diagnostic efficiency in US,US+SWE and US+SWE+3D-SMI for PA and WT by receiver operating characteristic(ROC) curve.Results:Pathological results showed that 54 tumors were PA and 31 tumors were WT.There were significant differences between PA and WT in "calcification(χ2 =6.506),hypoecho or anecho(χ2 =16.029),grid echo(χ2 =24.070),the average Young modulus(t=4.988),internal vascularity(χ2 =32.690) and vascular distributions(χ2 =26.908)".The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of US+SWE+3D-SMI in the diagnosis of PA and WT were 80.65%,87.04%,84.71%,78.13% and 88.68%.The diagnostic efficiency of US+SWE+3D-SMI was significantly better than that of US,and the AUC of US+SWE+3D-SMI was significantly higher than that of US(0.838 vs 0.596;Z=4.990,P<0.001).Conclusion:The diagnostic efficiency of multimodal ultrasound is better than conventional ultrasound.Multimodal ultrasound(US+SWE+3D-SMI) can help to differentiate PA and WT.
