Learning objectives To clarify the side effects of iodinated contrast media (ICM) on the thyroid function.To identify contraindications of ICM in cases of thyroid pathology.To specify how to identify and manage patients at risk.
Read more Background During the past decades, the number of radiological examinations, particularly computed tomography (CT) and vascular interventional procedures, which require iodine-based contrast media (ICM) has risen dramatically. Despite the increasingly common use of ICM in daily medical practice, particularly in imaging, radiologists are not aware of their contraindications and side-effects on thyroid function. While the effects of ICM on the risk of nephropathy have been extensively studied, there have been few studies on the risks of altering thyroid function. Although rare,...
Read more Findings and procedure details ICM are iodine-rich drugs administered in significant quantities during radiological investigations, well in excess of the recommended daily amount of iodine, equivalent to an acute dose.The daily iodine intake recommended by the World Health Organization is 150 µg/day (1). The prevalence of ICM-induced thyroid dysfunction varies from 1 to 15% according to recent studies (2). Side effectsThe excess of iodine can cause acute thyroid dysfunction, particularly in patients at risk. It can lead to hyperthyroidism or hypothyroidism, with numerous complications, such...
Read more Conclusion ICM are frequently used in imaging. It is therefore essential to radiologists to be aware of the possible complications for the thyroid. Patients at high risk must be identified so that appropriate management can be applied.
