The purpose of this study were to analyze the clinical correlation between the thyroid autoimmune antibodies (anti-TPO Ab, anti-TG Ab, and TSH) and the maximum standardized uptake value (SUVmax) base on the Hashimoto’s thyroiditis and the Graves’ disease in diffusely 18F-FDG uptake of the thyroid gland to the PET/CT image. To achieve this, we was performed the PET/CT examination for the 1,097 subjects from May 2010 to April 2013 in the health screening, and was detected the diffused FDG thyroid uptake, and was additionally performed the thyroid function test (TFT) and the ultrasound (US). As a results, the autoimmune thyroid disease with the diffused FDG thyroid uptake were discovered 39 patients (3.9%), of this, the Hashimoto’s thyroiditis was 43.6% and the Graves’ disease was 23.1%. Hashimoto’s thyroiditis was shown the positive reaction of high titer between the anti-TPO Ab and the anti-TG Ab level, and the correlation coefficient between the SUVmax and the anti-TPO Ab was a statistically significant (r>04, p<0.05). Also, Graves’ disease was shown the positive reaction of high titer most of the thyroid autoimmune antibodies, and the correlation coefficient between the SUVmax and the anti-TPO Ab was a statistically significant (r>05, p<0.01). Therefor, when have a high standard of the SUVmax due to the diffusely 18F-FDG uptake of the thyroid gland, Hashimoto’s thyroiditis and Graves’ disease were proportionally increased the anti-TPO Ab and TSH level, respectively. The correlation coefficient between the SUVmax and the thyroid autoimmune antibodies will be the most influential criterion that was a standard of judgment for the epihpenomenon of the autoimmune thyroid disease, and it will be available for the clinical application.
