There is homoegenous intense uptake of tracer by the thyroid gland. The thyroid appears enlarged. Uptake in tissue above the isthmus likely reflects a pyramidal lobe. No dominant hot or cold thyroid nodules are identified.
Uptake in the background soft tissues is suppressed, quantified by the markedly elevated neck to thigh ratio (normal <6).
The classic appearance of Graves disease on pertechnetate thyroid scintigraphy is markedly increased tracer accumulation in an enlarged gland, with corresponding reduction of physiological activity in the background tissues.
