目的 评价核素显像对甲状腺结节的诊断效能以及甲状腺结节功能与病理的关系。方法 对 85例甲状腺结节患者使用针孔型准直器 ECT甲状腺显像 ,并与手术、病理检查对照。结果 ECT对甲状腺结节诊断的灵敏度85 .7%。其中结节直径在 1.0 cm以上的灵敏度为 95 .3% ,结节直径在 1.0 cm以下的 5 3.8% (P<0 .0 1)。结论 结节的良恶性与结节功能密切相关 ,结节功能越低 ,恶性可能性越大。
Objective To evaluate the diagnostic efficacy of radionuclide imaging in thyroid nodules and the relationship between thyroid nodule function and pathology. Methods 85 cases of thyroid nodules were treated with pinhole collimator ECT thyroid imaging and compared with the operation and pathological examination. Results The sensitivity of ECT to the diagnosis of thyroid nodules was 85.7%. The sensitivity of nodules with diameter above 1.0 cm was 95.3% and the diameter of nodules was 5.8% (P <0.01) below 1.0 cm. Conclusion The benign and malignant nodules are closely related to nodule function. The lower the nodule function, the greater the possibility of malignancy.
