ABSTRACT
Objective The Aim Of This Study Was To Assess Chronic Inflammatory Conditions Of Major Salivary Glands By Shearwave Elastography. Patients And Methods 21 Patients With Chronic Inflammatory Conditions Of Major Salivary Glands And 21 Healthy Adult Volunteers Were Included In This Study. All Participants Underwent B-mode Sonography And Shearwave Elastography. The Diagnostic Performance Of Shearwave Velocity Was Evaluated By Sensitivity And Specificity At The Optimum Cutoff Point And The Area Under The Receiver Operating Characteristic Curve. Results Cases Showed Statistically Significantly Higher Median Shearwave Velocity Of Parotid Gland Than Control Group (P-value = 0.022, Effect Size = 1.119). There Was No Statistically Significant Difference Between Median SW Velocity Of Submandibular Gland In The Two Groups (P-value = 0.216, Effect Size = 0.576). As Regards The Total Scores; Cases Showed Statistically Significantly Higher Median Scores Than Control Group (P-value <0.001, Effect Size = 1.301). At Cut-off Value Of (23.5), Shearwave Velocity Showed 78.6% Diagnostic Accuracy With A Sensitivity Of 81% And Specificity Of 76.2% With 0.819 Area Under The Curve Of Receiver Operator Characteristics And Confidence Interval Was 0.669-0.920. Conclusion Shearwave Elastography Technique Might Be A Useful Noninvasive Strategy For Assessment Of Salivary Glands In Chronic Inflammatory Conditions.
