Observational Study on Hypothyroidism in young Children following Iodine Contrast Exposure

Trial purpose

To investigate the incidence of detected hypothyroidism after iodinated contrast exposure in pediatric patients from birth to 3 years of age (inclusive) in a routine clinical practice setting.

Key Participants Requirements

Sex

Both

Age

0 - 3 Years
  • - All children age 0-3 years (inclusive) who are identified of having undergone a radiological examination with intravascular use of an iodinated contrast agent.(e.g.
    contrast enhanced CT, cardioangiography)
  • - Congenital Hypothyroidism or other forms of preexisting hypothyroidism
    - Preexisting thyroid hormone replacement therapy less than three months of observation before the radiological examination (if greater than three months
    old)
    - Less than two weeks follow-up available after the contrast exposure.
