Abstract:
Objective To investigate the value of shear wave elastography (SWE) indirect evaluation on parotid function in Sjogren syndrome (SS) patients.Methods According to parotid function evaluated with scintigraphy,100 SS patients were divided into normal group,mild group,moderate group or severe group.SWE was performed in all the patients,and Young's modulus of parotid gland was obtained.The difference of Young's modulus among the four groups were compared,and the correlation between Young's modulus and paratid gland function were analyzed.ROC curve was used to evaluate the efficacy of Young's modulus in diagnosis of severe parotid function damage.Results The difference of Young's modulus among four groups was statistically significant (F=78.60,P＜0.001).Young's modulus increased with the damage severity of parotid function (rs =0.83,P＜0.001).Taking 38.38 kPa as threshold,the area under ROC curve of Young's modulus was 0.93 (P＜0.001) in diagnosis of severe parotid function damage and the sensitivity and specificity was 89.3％ and 84.7％,respectively.Conclusion SWE can indirect evaluate parotid function in SS patients,and is valuable in diagnosis and long-term follow-up of SS.
