Discordant imaging of a thyroid nodule with 131I and 99mTc: concordance of 131I and fluorescent scans.
A thyroid nodule, "hot" by 99mTc and "cold" by 131I scanning, was reimaged with a fluorescent scanner. The fluorescent scan was qualitatively similar to the 131I scan and demonstrated low iodine content in the nodule. This combination of scan patterns is compatible with an organification defect in the nodular tissue.
