Question 1

What is the purpose of Thyroid Scintigraphy?

Answer 1

To determine if a thyroid nodule is hyperfunctioning (increased uptake of radioisotope leg, radioiodine]) or nonfunctioning (decrease uptake of radioisotope).

A hyperfunctioning nodule is less likely to be malignant.

A nonfunctioning nodule is more likely to be malignant.
