我们回顾性评估了 1987 年至 2000 年间接受手术的 275 名腮腺肿瘤患者（283 个腺体）的术前放射性同位素 (RI) 闪烁扫描。对 201 个腺体进行了 Technetium-99m-pertechnetate (Tc) 闪烁扫描。嗜酸细胞瘤和沃辛氏瘤阳性率较高。在用 Tc 闪烁扫描评估 Warthin 肿瘤时，敏感性为 75%，特异性为 88%； 40岁以上，特异性超过90%。对 207 个腺体进行了 67-柠檬酸镓 (Ga) 闪烁扫描。腮腺恶性肿瘤的阳性率较高（85%），但阳性结果的特异性相当低（38%），因为占据主要材料的良性多形性腺瘤中有44%显示Ga阳性结果。 Ga 阴性结果表明良性肿瘤的可能性很高（95%）。因此，Tc 闪烁扫描可有效诊断 Warthin 肿瘤，而 Ga 闪烁扫描可有效诊断良性肿瘤。
We retrospectively evaluated preoperative radioisotope (RI) scintiscans in 275 patients (283 glands) with parotid tumors who undergoing surgery between 1987 and 2000. Technetium-99m-pertechnetate (Tc) scintigraphy was conducted on 201 glands. Oncocytoma and Warthin's tumor showed a high positive rate. In evaluating Warthin's tumor with Tc scintigraphy, sensitivity was 75% and specificity 88%; above the age of 40 years, specificity exceeded 90%. Gallium-67-citrate (Ga) scintigraphy was conducted on 207 glands. Malignant parotid tumors showed high positivity (85%), but the specificity of positive findings was quite low (38%) because 44% of benign pleomorphic adenoma, which occupied major material, showed Ga-positive findings. Ga-negative findings indicated high probability (95%) of benign tumors. Thus, Tc scintigraphy is effective in diagnosing Warthin's tumor, while Ga scintigraphy is effective in diagnosing benign tumors.
