Quizplus · Accepted Answer

A thyroid scan utilizes the uptake of radioactive iodine by the thyroid gland to determine the size, shape, and function of the gland. Also identified are areas of increased uptake (hot areas), indicating increased metabolic function, as in hyperthyroidism, not malignancy (choice B) and areas of decreased or no uptake (cold areas), which are associated with malignancy. Choices A and D both describe the TSH stimulation test.
