Evolution of Imaging for Diagnosis of Abnormal Migration of the Thyroid Gland

In May 1971, Ashkar et al introduced a novel technique of dynamic imaging to identify malformed or ectopic thyroid tissue. They emphasized the benefits of technetium-99m (Tc-99m) over the conventional I-131 for this diagnostic purpose. Tc-99m has low-energy gamma emissions with almost no beta emissions, a shorter half-life which allows for a faster study, and less production cost than conventional I-131.
