Abstract:
Objective To explore the value of ultrasound in assessment of treatment effect of diffuse toxic goiter.Methods 80 diffuse toxic goiter patients with 131I therapy were selected as research subjects.Before and after treatment,the serum thyroid hormone levels were detected and thyroids were checked by ultrasound.Results Before and after treatment,the FT3 levels were positively correlated with blood flow area ratio and flow grade (r =0.472,0.593,all P ＜ 0.05).After treatment,the thyroid weight,peak systolic velocity(PSV) and end diastolic velocity (EDV) [(12.89 ± 7.86) g,(32.24 ± 21.85) cm/s,(12.36 ± 19.22) cm/s] were significantly lower than those of before treatment [(30.12 ± 17.24) g,(68.58 ± 34.25) cm/s,(28.03 ± 21.24) cm/s] (t =11.265,4.762,3.672,all P ＜ 0.05).Before and after treatment,the RI and PI showed no significant difference(all P ＞ 0.05).The difference of thyroid blood flow grade before and after treatment was statistically significant (x2 =98.959,P =0.000),the proportion of flow grade class Ⅲ before treatment was higher(80.0％),while the proportion of flow grade class Ⅰ after treatment was higher(60.0％).After treatment,the FT3 and FT4 levels [(6.88 ± 4.14)pmol/L,(17.23 ± 7.35)pmol/L]were significantly lower than those of before treatment [(18.79 ± 6.45) pmol/L,(56.47 ± 22.97) pmol/L] (t =17.243,13.254,all P ＜ 0.05).The TSH level [(11.52 ± 8.27) mU/L] was significantly higher than that of before treatment[(0.01 ± 0.00)] mU/L (t =3.365,P ＜ 0.05).After treatment,the thyroid weight,PSV and EDV of cure group[(9.34 ±2.36) g,(20.13 ± 8.59) cm/s,(9.13 ± 5.34cmn/s)] were lower than those of non-cure group [(18.78 ± 8.76) g,(52.32 ± 13.24) cm/s,(17.24 ± 8.34crn/s)] (t =9.143,8.793,5.232,all P ＜ 0.05).The differences of RI and PI in the cure group and non-cure group were not statistically significant (all P ＞ 0.05).Conclusion Ultrasound has a better role in the evaluation effect of 131I therapy for diffuse toxic goiter.
