Abstract
Objective To explore the value of virtual touch tissue quantification(VTQ) in diagnosis of mucoepidermoid carcinoma (MECa) of parotid gland.Methods The sonographic and VTQ findings of 36 patients with MECa of parotid gland proved by pathology were analyzed retrospectively.The patients were divided into 3 groups according to pathology.50 normal subjects were choesn as control group.Results There were significant differences of shear wave velocity (SWV) between MECa groups and control group as well as among MECa groups (all P ＜0.01).Conclusions VTQ provides quantitative information about tissue stiffness which is useful for the diagnosis of MECa of parotid gland. Key words: Ultrasonography; Parotid neoplasms ; Carcinoma, Mucoepidermoid; Virtual touch tissue quantification
