Value of radioactive iodine uptake and thyroid imaging in diagnosis of painless thyroiditis

Objective To evaluate clinical value of radioactive iodine uptake and thyroid imaging in diagnosis of painless thyroiditis(PT). Methods Seventy cases of PT patients, 50 cases of GD patients and 50 cases of healthy persons were retrospectively analyzed by using radioactive iodine uptake, thyroid imaging and serological examination. Results PT group radioactive iodine uptake rate was significantly lower than the control group, GD group was significantly higher than the control group, PT group and the GD group difference was significant (F=64.88, P＜0.01). Thyroid image of PT group is not clear, or no to be seen, thyroid image of GD group can be clearly visible. Conclusion Radioactive iodine uptake and thyroid imaging play an irreplaceable role in the identification of PT and GD, and the method is simple and effective too. Key words: Painless thyroiditis; Radionuclide imaging; Iodine uptake rate
