Thyroid scan
Alternative names:
nuclear scan - thyroid; radioactive iodine screening test, thyroid; RAUI; scan - thyroid
Normal values:
The thyroid appears the correct size, shape, and in the proper location. It appears a uniform gray on the computer.
What abnormal results mean:
If the thyroid is enlarged or pushed off to one side, this could indicate a tumor. Nodules will absorb more or less iodine and will appear darker or lighter on the scan (usually lighter if tumor). If part of the thyroid appears lighter, it may indicate there is possible thyroid dysfunction.
Additional conditions under which the test may be performed:
