Radioactive iodine post-therapeutic imaging findings. Post-therapeutic WBS reveals multifocal uptake in the thyroid bed and extra-thyroid areas, following the initial RAI therapy (A). Additional single-photon emission tomography/computed tomography imaging obtained on the same day as post-therapeutic scintigraphy shows focal uptake in the submental area (B) and right thyroid bed (C). After the second RAI therapy, there was no abnormal uptake suggestive of remnant thyroid or tumor recurrence on the post-therapeutic WBS (D). WBS, whole-body scintigraphy; RAI, radioactive iodine.
