A type of nuclear scan that examines the thyroid after a person is given (by mouth or intravenously) a small amount of radioactive material that contains iodine or technetium. For a short period, the radioactive material emits radiation. A special camera, called a gamma camera, is used to determine the amount of radiation that has been absorbed by thyroid nodules. Cold nodules are nodules that absorb less radioactive material than the surrounding thyroid tissue. Whereas, hot nodules are nodules that absorb more radioactive material.
