Post-ablation whole body scans of one patient from each group. No significant difference was evident with respect to pathologic staging (T1 N1a Mx) or administered 131I dose (3.70 GBq). a In the patient without midline uptake, no significant pre- to post-ablation change in serum thyroglobulin (Tg) level was observed (0.3 ng/mL and Tg ratio 1.00). b However, in the patient with midline uptake, although pre-ablation Tg was almost the same (0.4 ng/mL) as in the patient without midline uptake, post-ablation serum Tg was significantly elevated to 18.1 ng/mL and Tg ratio was 45.25
