Comparison of ultrasonography and CT for evaluation of Sjogren syndrome

Objective: To evaluate value of ultrasonography and CT sialography in the diagnosis of Sjogren syndrome(SS).Methods: Ultrasonography and CT sialography detection were conducted on 56 cases of primary Sjogren syndrome confirmed by Labial Salivary Gland Biopsy and 32 normal healthy controls.Images revealed by the two methods were compared.Results: The sensitivity,specificity and accuracy of ultrasonography were 90%,91% and 80%respectively,while those of CT sialography were 81%,93% and 76% respectively showing no significant difference between the two methods(P0.05).Conclusions: As for diagnosis of Sjogren syndrome,ultrasonographymay can be used for screening up,and Labial Salivary Gland Biopsy should be applied for those without typical ultrasonography images.
