甲状腺结节功能的定量分布

QUANTITATIVE ANALYSIS OF THE FUNCTION OF THYROID NODULE

目的 :探讨用比值法判断甲状腺结节功能状态的价值。方法 :用单光子发射型计算机断层 (SPECT)对甲状腺结节进行核素甲状腺平面显像 ,分别用目测法和比值法判断甲状腺结节功能。结果 :目测法判断甲状腺结节的功能状态存在一定主观性 ,特别是对放射性分布差异不很明显的过渡区域的结节 ,可能有判断不同的结果 ,而比值法能客观准确地判断此类甲状腺功能状态。结论

Objective:To discuss the value of ratio method to estimated the function of thyroid nodule.Method:We estimated the function of thyroid nodule with eye estimation and ratio method respectively on radionuclide planar imaging of thyroid for thyoid nodule by means of single photon emission compare tomography (SPECT).Results:Eye estimation was likely to be subjective,especially when some transitional areas of nodules were not obvious due to the different distribution of radioactivity,while ratio method was more objective in judging the function of thyroid nodule.Conclusion:Rate method is more acurate and objective in detecting the function of nodulars in thyroid.
