What is the purpose of the thyroid assessment before examinations involving iodinated contrast media?

The purpose of the thyroid assessment before examinations involving iodinated contrast media is to check for thyroid disorders. Iodinated contrast can affect the thyroid gland's function, especially in patients who have pre-existing thyroid conditions such as hyperthyroidism or hypothyroidism. These disorders can lead to abnormal reactions during or after the administration of the contrast media, as the iodine in the contrast can interfere with thyroid hormone production and regulation.

Before imaging procedures using iodinated contrast, healthcare providers assess thyroid function to ensure patient safety, particularly to avoid exacerbation of any thyroid conditions. This is a crucial step in patient care to minimize the risk of adverse reactions and ensure the accurate interpretation of imaging results.
