【摘要】目的对99m锝1,2双〔双(2乙氧乙基)膦基〕乙烷(99mTctetrofosmin,99mTcTF)显像与颈部彩色多普勒超声(color doppler ultrasonography,CDU)检查对甲状腺“冷结节”性质判定的结果进行对比分析,以明确99mTcTF显像在判定甲状腺“冷结节”性质中的价值。方法选择经99mTcO-4显像证实为甲状腺“冷结节”60岁以上的患者60例,以术后病理结果为标准,分别对99mTcTF显像及颈部CDU检查在96处甲状腺“冷结节”、62处直径>1 cm的甲状腺“冷结节”中的判定结果进行对比分析。结果病理结果示96处甲状腺“冷结节”中良性52处,恶性44处。%,99mTc%,两种手段间准确率比较无显著差异()。病理结果示直径>1 cm的62处甲状腺“冷结节”中良性34处、恶性28处。%,较其在甲状腺“冷结节”中判定的准确率无显著性差异();99mTc%,较其在甲状腺
“冷结节”中,判定的准确率增高()。99mTcTF显像判定准确率高于颈部CDU()。结论 99mTcTF显像在直径较大的甲状腺“冷结节”的性质判定准确率优于颈部CDU检查。

【Abstract】 Objective To identify the diagnosis value of 99mTctetrofosmin imaging in thyroid “cold nodule” paring the diagnostic results of 99mTctetrofosmin imaging and neck Color Doppler Ultrasonography (CDU). Methods 60 patients with thyroid “cold nodule” determined by 99mTcO-4 imaging were chosen. Regarded pathological result as the standard pared diagnostic value of 99mTctetrofosmin imaging and neck CDU in analyzing 96 thyroid “cold nodules”,62 thyroid “cold nodules” with diameter greater than 1 cm respectively. Results There were 52 cases of benign,44 cases of malignancy in 96 thyroid “cold nodules”. The accurate of neck CDU and 99mTcTF were % and 7
