Overview
Thyroid radionuclide uptake and scanning may be helpful in the diagnosis of cretinism. The absence of the radionuclide uptake is consistent with some thyroid gland anomalies like ectopic thyroid gland, thyroid gland hypoplasia, and thyroid aplasia.
Other Imaging Findings
Thyroid radionuclide uptake and scan
- The thyroid radio-scan may be helpful in the diagnosis of cretinism. It is preferred for the neonates as there is less radioactivity exposure. Radionuclide scanning is the most accurate test to diagnose cretinism caused by thyroid dysgenesis.[1]
- The absence of the radionuclide uptake is consistent with the following thyroid gland anomalies:
- The high radionuclide uptake is consistent with thyroid dyshormonogenesis.
