Abstract:
Objective: To observe the manifestations of focal thyroiditis and papillary thyroid carcinoma (PTC) of conventional ultrasound and real-time shear wave elastography (SWE). Methods: Ultrasonic data of 36 thyroditis patients and 100 PTC patients (50 with Hashimoto's thyroiditis [HT]) confirmed pathologically were retrospectively analyzed, and the performances of conventional ultrasound and Young's modulus value were compared. Results: All thyroid nodules in 136 cases were solid. No significant difference of nodules' location, number, diameter, morphology nor internal calcification was found (all P>0.05), while statistically significant differences of obscure boundary, internal echo and aspect ratio>1 were detected between focal thyroiditis and PTC (all P<0.05). There was no difference of Emax, Emin and Emean of Young's modulus value between focal thyroidtis and PTC (all P>0.05), nor between patients with and without HT (all P>0.05). Conclusion: The ultrasonographic manifestations were somehow different between focal thyroiditis and PTC, being helpful to differential diagnosis. SWE showed no significant differential diagnostic value for focal thyroidtis and PTC, which was not obviously affect by combination of HT or not.
