目的 :评价甲状旁腺功能亢进症 (甲旁亢 ) 99mTc MIBI/99mTcO4-显像的临床价值 ,并与B超和CT比较。方法 :2 2例拟诊甲旁亢患者进行了核素显像 ,显像资料均参照临床最终诊断结果进行了评价 ,并与同期的B超 (2 2例 )或CT检查 (12例 )进行对比分析。结果 :2 2例患者中 ,18例确诊为甲旁亢 ,其中甲状旁腺瘤 16例 ,甲状旁腺增生2例。99mTc MIBI/99mTcO4-减影法、B超、CT的灵敏度分别为 88 9%、77 8%、80 %。特异性均为 10 0 % ,准确性为90 9%、81 8%、77 8%。99mTc MIBI/99mTcO4-减影法显像较B超和CT具有更高的诊断价值。结论 :99mTc MIBI/99mTcO4-显像对功能亢进的甲状旁腺有较好的诊断价值 ,是患者术前定位的重要辅助诊断手段 Objective: To evaluate the clinical value of 99mTc MIBI / 99mTcO4-imaging in hyperparathyroidism (hyperparathyroidism) and to compare with B-mode ultrasonography and CT. Methods: Twenty-two cases of suspected hyperparathyroidism underwent radionuclide imaging. The imaging data were evaluated with reference to the final clinical diagnostic results. The data were compared with those of B-mode ultrasound (12 cases) or CT (12 cases) Comparative analysis. Results: Of the 22 patients, 18 were diagnosed as hyperparathyroidism, including 16 cases of parathyroid adenoma and 2 cases of parathyroid hyperplasia. The sensitivity of 99mTc MIBI / 99mTcO4-subtraction, B-ultrasound and CT were 88.9%, 77.8% and 80% respectively. Specificity was 100%, accuracy was 90 9%, 81 8%, 77 8%. 99mTc MIBI / 99mTcO4-subtraction imaging than B-and CT have a higher diagnostic value. CONCLUSION: 99mTc MIBI / 99mTcO4-imaging is of value in the diagnosis of hyperparathyroidism, which is an important diagnostic aid for preoperative localization
