【摘要】 目的　评价甲状腺肿瘤术前各种诊断方法的临床意义。方法　根据手术标本组织病理学诊断结果将36名单发性实质性甲状腺结节的患者分为良性肿瘤组 (A组 ,16名 )、恶性肿瘤组 (B组 ,2 0名 ) ,探讨其术前所行B型超声波 (B超 )、99mTc同位素扫描、B超引导细针穿刺细胞学诊断 ,以及测定血清甲状腺免疫球蛋白 (Tg)等检查的临床意义。结果　B超显像中 ,结节内部回声不均匀 ,或伴有细小钙化灶显像类型在恶性肿瘤中明显较多出现 (P <0 .0 5 )。B超引导细针穿刺细胞学诊断的正确率为 77.8% (P <0 .0 1) ,具有一定的临床意义。两组的血清Tg水平、99mTc同位素扫描结果均无显著差异。结论　B超 (结节内部回声 ,伴有细小钙化灶显像 )、B超引导细针穿刺细胞学检查为两种较有效的检查手段。更多还原

【Abstract】 Purpose To evaluate utility of variant examinations in the preoperative management of thyroid nodules. Methods According to pathological findings of thyroidectomy,thirty six patients with single solid thyroid nodule divided to benign tumor group (group A,16) and malignant tumor group (group B,20).We investigated the differences of Ultrasonographic findings,USG guided fine needle aspirating biopsy (FNAB), 99m Tc isotop scan,and thyroglobulin levels before operation in the two groups. Results Hete rogenous internal echoes and small strong echoes were more found in group B than A ( P <0.05).Accuracy of USG guided FNAB was 77.8% in this study. 99m Tc isotop scan,and thyroglobulin leves were less useful criteria. Conclusions Ultrasonography (internal echoes and small strong echoes) and FNAB were avai lable in the preoperative management of thyroid nodules.更多还原
