Abstract:
Thyroid hormones T3 and T4 are crucial for development and differentiation of various cells in the body. They are also essential for regulating metabolism in nearly all tissues. Iodine is an integral element in the synthesis of thyroid hormone and is actively transported into the thyroid by a Na+/I- symporter. The thyroid can take up radioactive iodine just like it would take iodine and hence can be used to evaluate and treat several thyroid diseases. Radioactive iodine is one of the first radioisotopes to be used in medicine.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
Positron Emission Tomography
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
