One of the major limitations of planar I-131 imaging is its lack of anatomic precision. SPECT/CT offers the benefit of precise anatomic localization that planar imaging lacks. Whether for confirmation of physiologic uptake or true pathology, SPECT/CT has an important role to play in clarifying equivocal findings. We present a case of papillary thyroid cancer metastatic to the liver, a relatively rare scenario. SPECT/CT allowed definitive lesion characterization at the time of the patient's visit to the nuclear medicine department.
平面 I-131 显像的主要局限性之一是其缺乏解剖学精确性。SPECT/CT 具有平面显像所缺乏的精确解剖定位优势。无论是用于确认生理性摄取还是真正的病变，SPECT/CT 在明确可疑发现方面都发挥着重要作用。我们报告一例甲状腺乳头状癌转移至肝脏的病例，这是一种相对罕见的情况。在患者前往核医学科就诊时，SPECT/CT 能够对病变进行明确的特征描述。
