Sodium Iodide (I123)

Sodium Iodide (I123) is a radiopharmaceutical used for diagnostic imaging of thyroid function and structure. This non-therapeutic agent helps assess iodine uptake in the thyroid gland. Short half-life minimizes radiation exposure. Ideal for thyroid scans and uptake tests.

Sodium Iodide (I123) is primarily used for diagnostic imaging of the thyroid gland. It helps evaluate thyroid function and detect abnormalities such as nodules or hyperthyroidism. The radiopharmaceutical is administered to measure iodine uptake, aiding in the assessment of thyroid health and potential disorders.

After administration, Sodium Iodide (I123) is absorbed by the thyroid gland, allowing for imaging of its structure and function. Patients may experience mild discomfort at the injection site or temporary metallic taste. The effects are temporary and resolve as the radiopharmaceutical is cleared from the body.

Sodium Iodide (I123) should only be handled and administered by trained healthcare professionals. Pregnant or breastfeeding individuals should avoid exposure due to potential risks to the fetus or infant. Patients should inform their healthcare provider of any allergies or thyroid conditions before use.

Certain medications, such as thyroid hormones or antithyroid drugs, may interfere with the uptake of Sodium Iodide (I123). Patients should disclose all current medications to their healthcare provider. Alcohol and iodine-containing supplements may also affect test results.
