Clinical Trial Outcome Measures

Primary Measures

  • Abnormal thyroid function
    • Time Frame: Day 1 to 2 months
    • The primary outcome of this study is to evaluate the proportion of subjects, 0 to 3 years of age, developing abnormal thyroid function after administration of ISOVUE.

Secondary Measures

  • Hypothyroidism
    • Time Frame: Day 1 to 2 months
    • To evaluate the proportion of subjects, 0 to 3 years of age, with hypothyroidism regardless of the need for thyroid hormone therapy after administration of ISOVUE.
  • Thyroid hormone replacement therapy
    • Time Frame: Day 1 to 12 months
    • The proportion of subjects initiated on thyroid hormone replacement therapy.
