Hyperthyroidism (cont.)

Images of Hypothyroidism

X=Ray Image of Radioactive Scan of Toxic Multinodular Goiter

Figure 1 Above: Radioactive iodine scan of a patient with toxic multinodular goiter. Note the patchy and darker appearance of the nodules that are producing excess amounts of thyroid hormone. Compare this to the normal scan shown in Figure 1.

Radioactive Iodine Scan Image of Subacute Thyroiditis

Figure 2 Above: Radioactive iodine scan of a patient with subacute thyroiditis during the hyperthyroid phase. Note that there is very little iodine uptake in the thyroid. This is due to inflammation of the thyroid causing release of stored thyroid hormone (causing elevated thyroid hormone levels in the blood) and reduced iodine uptake.

Radioactive Iodine Thyroid Scan Image of Normal Thyroid and Image of Patient with Grave's Disease

Figure 3 Above: Radioactive iodine thyroid scan. Comparison between scans from the normal patient and a patient with Graves' disease. Note the overall increased uptake throughout the enlarged thyroid gland in a patient with Graves' disease.
