Abstract：Objective: To investigate the application value of shear wave elastography (SWE) in ultrasound-guided fine needle aspiration (FNA) of papillary thyroid carcinoma. Methods: The relevant data of 90 patients suspected of papillary thyroid carcinoma who were admitted to the hospital from January 2019 to December 2021 were retrospectively analyzed. All patients needed to undergo ultrasound-guided FNA. According to the ultrasound technique used, the patients were divided into conventional group (n=42, two-dimensional ultrasonography) and SWE group (n=48). The sampling results, the incidence of puncture complications, the pathological classification of Bethesda system, and the value in diagnosing benign and malignant lesions were compared between the two methods. Results: The success rate of sampling and the detection rate of 2 needles in the SWE group were higher than those in the conventional group, but only the detection rate of 2 needles showed a statistical significance (P<0.05). The incidence of puncture complications in the SWE group was significantly lower than that in the routine group (4.16% vs 21.42%, P<0.05). The pathological results of Bethesda classification system showed no statistically significant difference between the two groups, but the diagnosis rate of class II～VI in the SWE group was higher than that in the conventional group (P<0.05). With pathological results as the golden standard, the diagnostic sensitivity and accuracy in the SWE group for malignant lesions were higher than those in the conventional group (P<0.05). Conclusion: SWE is helpful for determining the location of FNA in patients suspected of papillary thyroid carcinoma, improving the detection rate of 2 needles, reducing puncture complications, and improving the diagnosis of papillary thyroid carcinoma to a certain extent.
