Other Imaging Findings

Differentiation based Functional (Nuclear) Imaging for Thyrotoxicosis

Functional (Nuclear) Imaging for Thyrotoxicosis
Diagnosis	Degree of Thyrotoxicosis	Radioactive iodine Uptake	Scintigraphy Image
Toxic multinodular goiter	+/++	Normal or +/++	Enlarged gland with multiple "hot" or "cold" nodules
Grave's disease	++++	++++	Enlarged gland with homogenous uptake
Thyrotoxic phase of subacute thyroiditis	++++	<1% at 4 or 24 hr.	Absent isotope uptake
Toxic adenoma	+/++	Normal or +/++	Dominant "hot" nodule with low or absent uptake in the surrounding normal gland.
