Hypothyroidism

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.
