摘要
目的研究甲状腺摄高锝酸盐(99mTcO4-)显像与甲状腺功能测定对甲状腺疾病的诊断价值。方法空腹采静脉血,测定血清促甲状腺素(TSH)和甲状腺激素含量;静脉注射显像剂前、后测定注射器的放射性计数,注射30min后作甲状腺显像并计算甲状腺摄99mTcO4-率。根据受检者临床表现及血清TSH、游离三磺甲状腺原氨酸(FT3)、游离甲状腺素(FT4)、甲状腺球蛋白抗体(TGAb)、甲状腺过氧化物抗体(TPOAb)含量及部分病理结果,分为甲状腺腺瘤组71例、单纯性甲状腺肿组24例、Grave’s病组200例、慢性淋巴细胞性甲状腺炎(HT)甲状腺功能亢进(甲亢)组21例和HT甲状腺功能减退(甲减)组29例,另设对照组95例,进行相关性分析。结果对照组甲状腺摄99mTcO4-率为(1.10±0.75)%,血清TSH为(1.50±0.98)μU/L、FT3为(6.34±1.84)pmol/L、FT4为(12.60±3.06)pmol/L。甲状腺腺瘤组甲状腺摄99mTcO4-率为(2.50±1.02)%,血清TSH为(1.47±0.61)μU/L、FT3为(7.11±1.04)pmol/L、FT4为(13.10±2.84)pmol/L。单纯性甲状腺肿组甲状腺摄99mTcO4-率为(2.80±0.98)%,血清TSH为(2.69±1.44)μU/L、FT3为(8.29±1.42)pmol/L、FT4为(11.5±2.23)pmol/L。Grave’s病组甲状腺摄99mTcO4-率为(7.40±4.97)%,血清TSH为(0.17±0.21)μU/L、FT3为(17.40±2.31)pmol/L、FT4为(2.80±3.04)pmol/L。HT甲亢组甲状腺摄99mTcO4-率为(6.10±4.69)%,血清TSH为(0.31±2.46)μU/L、FT3为(15.40±7.34)pmol/L、FT4为(22.90±15.44)pmol/L。HT甲减组甲状腺摄99mTcO4-率为(1.70±1.00)%,血清TSH为(35.80±17.41)μU/L、FT3为(4.57±1.41)pmol/L、FT4为(5.99±2.83)pmol/L。对照组与甲状腺腺瘤组、单纯性甲状腺肿组、HT甲减组甲状腺摄99mTcO4-率的差异有显著性(P<0.05),与Grave’s病组、HT甲亢组的差异亦有显著性(P<0.01);对照组与甲状腺腺瘤组、单纯性甲状腺肿组甲状腺激素含量的差异无显著性(P>0.05),与Grave’s病组、HT甲亢组、HT甲减组的差异有显著性(P<0.01)。甲状腺腺瘤组、Grave’s病组、HT甲减组甲状腺摄99mTcO4-率与甲状腺激素含量相匹配。甲状腺腺瘤组、Grave’s病组甲状腺摄99mTcO4-率均高于正常值;前者甲状腺激素含量正常,后者异常。单纯性甲状腺肿组、HT甲亢组甲状腺摄99mTcO4-率与甲状腺激素含量不匹配。两组摄99mTcO4-率均增高;单纯性甲状腺肿组甲状腺激素含量正常,HT甲亢组异常。HT甲亢组和HT甲减组甲状腺摄99mTcO4-率与甲状腺激素含量呈“分离现象”。结论甲状腺摄99mTcO4-率显像能反映甲状腺的位置、大小、形态、甲状腺及其包块的摄取情况,结合甲状腺血清学指标,其在甲状腺疾病的诊断、鉴别诊断、治疗及随访中均具有重要的临床价值。
Objective To study the diagnostic value of ~99mTcO^-4 uptake rate and the thyroid hormonal le-vels in thyroid disease.Methods Serum thyroid hormones and antibodies were determined in all patients, ~99mTcO^-4 uptake rate were calculated after thyroid imaging. Correlative analyses were performed among the control group, thyroid adenoma group, simple goiter group, Graves’s disease group, HT hyperthyroidism group, and HT hypothyroidism group. These groups were distinguished by clinical presentations, serum thyroid hormones(TSH,FT3,FT4) and antibodies(TGAb,TPOAb), and partly by pathologic results.Results ~99mTcO^-4 uptake rate in thyroid adenoma group, simple goiter group, and HT hypothyroidism group were the higher than those in the controls (P<0.05). ~99mTcO^-4 uptake rate in Graves’s disease group and HT hyperthyroidism group were the markedly higher than those in the controls (P<0.01). There were no differences in serum thyroid hormones among thyroid adenoma group, simple goiter group and the controls. However, there were marked differences among Graves’s disease group, HT hyperthyroidism group; HT hypothyroidism group, and the controls. ~99mTcO^-4 uptake rate was matching with serum thyroid hormones in thyroid adenoma group, Graves’s disease group, HT hypothyroidism group, serum thyroid hormones and ~99mTcO^-4 uptake rate were not matching in simple goiter group and HT hyperthyroidism group. Isolate phenomena was observed between ~99mTcO^-4 uptake rate and serum thyroid hormones in HT hyperthyroidism group and HT hypothyroidism group.Conclusion ~99mTcO^-4 thyroid imaging and uptake rate determinations can accurately reflect the size, shape and radioactivity distribution of the gland as well as presence of any nodule. Combined with serum thyroid hormones and antibodies measurement, the ~99mTcO^-4 study can be of great importance in the diagnosis and management of thyroid diseases.
