Abstract:
Objective To explore the value of shear wave elastography (SWE) in diffuse thyroid disease.Methods The elastic modulus were detected by SWE in 41cases of diffuse thyroid disease [including 16 cases of Graves' disease (GD),16 cases of Hashimoto' s thyroiditis (HT) and 9 cases of subacute thyroiditis(SAT)] and 30 cases of healthy volunteers.The elastic modulus,including Emean,Emin and Emax,were measured and compared.Results Compared with the normal group[Emean(15.7-± 2.5)kPa,Emin(11.6 ± 2.4)kPa and Emax (20.2 ± 3.0)kPa],the Emean[(20.4 ± 4.7)kPa],Emin[(14.4-± 3.8)kPa] and Emax [(27.8 ± 7.3)kPa] of GD,the Emean [(18.4-± 5.0)kPa] and Emax [(25.2 ± 5.8)kPa] of HT,and the Emean[(11.0 ± 2.9)kPa] and Emin [(6.0 ± 2.7)kPa] of the SAT were different significantly(P =0.001,0.007,0.001 ; P =0.045,0.001 ; P =0.000,0.000).There were significant differences between the SAT and the other two groups,namely GD and HT (P ＜0.05).Such differences,however,were not found between GD and HT (P ＞0.05).Conclusions SWE can be used to measure the elastic modulus of the thyroid tissue quantitatively and objectively,serving as a useful technique to predict the diffuse thyroid disease.
