Post-thyroidectomy I-131 whole-body scintigraphy is an important aspect in the management of patients with thyroid cancer. The scan is used to detect residual thyroid tissue and distant functioning metastases. Extrathyroid I-131 accumulation does not always denote metastatic disease, and several potential sources of false-positive I-131 scans have been identified. This report presents four cases of benign oral disease as a cause of false-positive I-131 uptake. Benign oral disease has not been documented previously as an important source of false-positive I-131 whole-body scans.
甲状腺切除术后 I-131 全身闪烁扫描是甲状腺癌患者管理中的一个重要方面。该扫描用于检测残留甲状腺组织和远处功能性转移灶。甲状腺外 I-131 聚集并不总是意味着转移性疾病，并且已经确定了几种 I-131 扫描假阳性的潜在来源。本报告介绍了 4 例良性口腔疾病导致 I-131 摄取假阳性的病例。良性口腔疾病以前未被记录为 I-131 全身扫描假阳性的重要来源。
