超声对甲状旁腺功能亢进症的诊断价值

目的　评价超声对甲状旁腺功能亢进症的诊断率及应用价值。方法　甲状旁腺功能亢进症患者 2 10例 ,比较分析其术前超声检查与手术所见和病理学诊断结果 ,并与核素和CT对比观察。结果超声对甲状旁腺功能亢进症诊断总的敏感性 68.62 % ,特异性 93 .79%。对甲状腺上极背侧病变的敏感性低于下极 (P <0 .0 5 ) ,对异位病变的敏感性低于正常部位 (P <0 .0 5 )。单从声像图上难以区分甲状旁腺腺瘤、增生或癌 ,需结合临床考虑。结论　超声是甲状旁腺功能亢进症术前定位的有效手段

Ultrasonography detection of parathyroid lesions in patients with hyperparathyroidism

Objective To evaluate the usefulness of ultrasonography in detecting parathyroid lesions in the patients with hyperparathyroidism. Methods The results of ultrasonography were compared with operative and histologic findings, and other imaging techniques such as 99m-Tc-sestamibi scintigraphy and CT in 210 patients with proved hyperparathyroidism.Results The overall sensitivity and specificity of ultrasonography in detecting parathyroid lesions were 68.62%, 93.79%. Lesions at lower pole of thyroid were more likely to be detected than ectopic ones. Ultrasonography was helpful in diagnosis of parathyroid adenoma, hyperplasia or carcinoma when combined with clinical manifestations. Conclusions Ultrasonography is a useful means in preoperative localizing of hyperparathyroidism.
