Whole body post-ablation scan. (A) Seven days following the administration of 1850 mBq ofI131. The image shows uptake in the thyroid bed and suggestive of uptake in one or more nearby lymph nodes. Additional mild increased activity is seen in the liver. Diffuse liver uptake may be seen on post-therapy scans and is indicative of thyroxine production. Thyroid hormone (T3, T4) is metabolized in the liver and activity can be seen there after 3–7 days. In post-ablation patients, liver activity suggest

Figure 2: Whole body post-ablation scan. (A) Seven days following the administration of 1850 mBq ofI131. The image shows uptake in the thyroid bed and suggestive of uptake in one or more nearby lymph nodes. Additional mild increased activity is seen in the liver. Diffuse liver uptake may be seen on post-therapy scans and is indicative of thyroxine production. Thyroid hormone (T3, T4) is metabolized in the liver and activity can be seen there after 3–7 days. In post-ablation patients, liver activity suggests that I-131 has been incorporated into thyroid hormone by functioning metastases or residual thyroid activity in the neck. (B) Anterior planar view showing I-131 uptake in the thyroid bed, as well as physiologic activity in the salivary glands and nasopharyngeal area. The area outlined in red is a substernal notch marker.
