Short-term effect of iodine contrast medium on thyroid function: a prospective cohort study.

ABSTRACT:

Background

Excess iodine intake due to iodinated contrast media (ICM) infusion during medical examinations is considered as a potential cause of thyroid abnormalities. However, the short-term effects of ICM exposure on patients in a Chinese population are not well elucidated.

Methods

In total, 200 patients who received intravenous ICM were enrolled, and their thyroid function was determined before ICM exposure (baseline) as well as 1 week and 1 month after the ICM infusion. The relationship between the peak urinary iodine concentration (UIC) and the contrast agent (CA) dose was then investigated. Three months after ICM exposure, the patients who developed thyroid dysfunction within 1 month of ICM exposure were followed up.

Results

This study included 125 males and 75
