Abstract:
Objective To investigate the conventional ultrasonic and elastographic characteristics of papillary thyroid micro-carcinomas(PTMC) suffered in normal and Hashimoto's thyroiditis(HT).Methods A total of 227 patients with 249 nodules that were confirmed by surgery or biopsy were included in this study.The cases were divided into normal group and HT group.All patients underwent conventional ultrasound and elastography (static pressure).The sonographic characteristics and strain ratio (SR) value were evaluated.Results In the normal group,the ratio between male and female was 1 ∶ 2.9,while in HT group,it was 1 ∶ 11,which was significant different between the two group (P =0.002).Sonographic characteristics that had no significant difference between the two groups (P >0.05) include:boundary,shape,vertical and horizontal ratio,halo,echogenicity,calcification,posterior shadowing,vascularity on color Doppler ultrasonography.The strain ratio value was statistically different between the two groups (P =0.034),with 3.44 ± 1.03 in normal group and 3.13 ± 1.13 in HT group.Conclusions The conventional ultrasonographic features of PTMC were similar in both normal thyroid and HT.However,females suffering HT were more susceptible to PTMC,and the strain ratio value of PTMC concomitant HT decreased.
