Thyroid blood flow imaging

The imaging of thyroid blood flow is performed with the imaging agent 99mTcO4-, because it can be taken up and concentrated by the gonad tissue, reflecting its uptake function. In addition to the cardiomyocytes, it can also accumulate in the hyperparathyroid tissue. The thyroid is the body's largest endocrine gland, and its blood supply is very rich. After the radionuclide is injected intravenously through a 'pellet', it is dynamically collected as it flows through the thyroid gland, which can reflect its blood flow. Usually performed in conjunction with static development.
