A cervical accumulation of radioiodine at Total Body Scan (TBS) in a patient who had been thyroidectomized for a follicular thyroid carcinoma led to unnecessary radioiodine treatment. Thyroglobulin measurements indicated constantly low levels. Following ultrasound scanning of the neck, echo-doppler examination of the cervical vessels and angiography with 99Tc, this area of increased activity at TBS imaging was shown to be due to an ectasia of the right common carotidis causing blood stasis and reverse flow.
一名因滤泡性甲状腺癌接受甲状腺切除术的患者在全身扫描（TBS）时出现颈部放射性碘聚集，导致不必要的放射性碘治疗。甲状腺球蛋白测量显示水平持续偏低。在对颈部进行超声扫描、对颈部血管进行回声多普勒检查以及用99Tc进行血管造影后，TBS成像中这个活性增加的区域被证明是由于右颈总动脉扩张导致血液淤滞和逆流所致。
