Abstract:
Objective:To evaluate the value of shear wave elastography (SWE) and salivary gland ultrasound scoring(SGUS) system in the diagnosis of salivary glands lesions in patients with Sj?gren′s syndrome(SS) and to compare the diagnostic efficiency of the two methods.Methods:From June 2019 to November 2020, Fifty-eight patients with suspected SS were selected from the Affiliated Changzhou No.2 People′s Hospital of Nanjing Medical University. According to the 2002 American-European Consensus Group classification standard, the enrolled patients were divided into two groups: SS group (47 cases) and non-SS group(11 cases). According to symptom duration, SS group was divided into the ≤5 years group (29 cases) and the >5 years group (18 cases). Meanwhile, 40 healthy volunteers were enrolled in this study as normal control group. The diagnostic value of salivary gland ultrasound scoring system and Young′s modulus in SS were analyzed.Results:The differences in Young′s modulus of parotid gland and submandibular gland between SS group and non-SS group (or control group) were statistically significant (all P<0.05). The ultrasound score of SS group was significantly higher than that of non-SS group and control group (all P<0.05). SGUS and Young′s modulus were not significantly different between different course groups (all P>0.05). The areas under ROC curve of the mean Young′s value in parotid and submandibular gland and the SGUS were 0.801, 0.829 and 0.676, respectively. The comparison of the area under the curve between the Young′s modulus of the parotid and submandibular glands and the ultrasound score was statistically significant (all P<0.05). Conclusions:SWE and Ultrasonography scoring system have certain value in the diagnosis of salivary gland lesions in SS, and can provide important reference information for clinical diagnosis from different perspectives. The diagnostic efficiency of SWE for salivary glands lesions in patients with SS is better than that of SGUS scoring system.
