Abstract
Objective Often the traditional Thyroid Uptake System (TUS) cannot accurately measure taken technetium rate. This paper aimed to discusses the effectiveness of Single Photon Emission Computed Tomography (SPECT)/CT after injection of99mTcO4 in detecting thyroid function abnormalities. Methods 60 patients of thyroid inspectors were analyzed retrospectively, including 20 cases of diffuse toxic goiter (Graves disease), 15 cases of thyroiditis and 25 cases of normal thyroid function. All patients were administered SPECT/CT after injection of99mTcO4, calculating thyroid uptake rate and Standardized Uptake Value (SUV), 20 Graves disease and 15 thyroiditis patients accept traditional determination of TUS in the same period.Results SPECT/CT quantitative evaluation parameters (thyroid uptake rate, average and maximum of standard intake) largest in Graves disease, followed by thyroiditis, minimum thyroid function in normal (P<0.001); TUS significantly overestimated the thyroid uptake rate compared with SPECT/CT (P<0.001) because other99mTcO4 sources in addition to thyroid contributed to the thyroid uptake rate result by TUS, whereas the SPECT/CT quantitative evaluation parameter with thyroid hormone levels has better correlation (P<0.05).Conclusion Quantitative SPECT/CT is more accurate than conventional TUS for measuring99mTcO4 thyroid uptake rate, also has important clinical value in the diagnosis of thyroid function disease.关键词
