Description
Estimated cost for Thyroid Scan at general public hospitals in China is about ¥140-400, and at Grade 3A hospitals about ¥200-500, varying by hospital tier and region.
Main Uses
Thyroid scans are primarily used to evaluate the structure and function of the thyroid gland. They help in diagnosing hyperthyroidism or hypothyroidism, identifying the presence and nature of thyroid nodules (hot or cold), and differentiating between benign and malignant thyroid conditions. Additionally, they are useful in planning treatment strategies such as surgery or radioactive iodine therapy.
Normal Range
The normal range for a thyroid scan typically involves assessing the uptake of radioactive iodine or technetium by the thyroid gland. A common indicator is the percentage of radioactivity uptake, which usually falls between 8-35% at 24 hours post-administration. The distribution should be even across both lobes without any hot or cold nodules.
Low Values - Possible Causes
Hypothyroidism, iodine deficiency, recent use of iodine-containing medications, non-thyroidal illness (sick euthyroid syndrome), and certain autoimmune diseases like Hashimoto's thyroiditis
High Values - Possible Causes
Hyperthyroidism, Graves' disease, toxic multinodular goiter, solitary toxic nodule, and thyroiditis (inflammatory conditions)
