| Objective: To explore the value of Quantitative analysis of color Doppler Flow Signals for Evaluation of Clinical Therapeutic Effect of hyperthyroidism.Methods: The throids of 30 patients with simple hyperthyroidism were examed by ultrasound for both throid volume calculation and color doppler flow signal ratio quantification,using DFY quantification software before the radioisotope iodine 131 (131I) treatment. And the throids were checked again by ultrasound at the time points of 1,3,6 months. The serum free triiodothyronine 3 (FT3) concentration were meausred each time before the ultrasound examination.Results: The thyroid volume and color flow signals and the total ROI area ratio decreased gradually after treatment, Jun Cheng, and FT3 serum concentrations of free positive correlation value of thyroid volume reduction of free serum FT3 concentration decreased value of the correlation coefficient of 0.4999 , P <0.0001. Color flow signals and the total ROI area of lower value than that of free serum FT3 concentration decreased the value of the correlation coefficient of 0.64371, P <0.0001, correlation coefficient of the latter than the former the former.Conclusion: The quantitative color Doppler flow signal dynamic analysis and thyroid volume change can be reflected in the course of treatment in patients with hyperthyroidism of free FT3 concentration level, but The color Doppler flow signal ratio should be better than the throid volume in the evaluation of FT3 level for the hyperthroidism patients, which could be very useful in the evaluation of Clinical Therapeutic Effect of hyperthyroidism. |
