目的:探讨201Tl/99mTcO-4双核素减影显像对原发性甲状旁腺功能亢进症(PHPT)的诊断优势。方法:对10例怀疑有原发性甲状旁腺功能亢进症(PHPT)的患者进行201Tl/99mTcO-4双核素减影显像检查,其中病理诊断PHPT5例(腺瘤3例,腺癌2例),非PHPT5例。结果:5例被确诊为PHPT的患者中,双核素减影显像阳性5例,与病理检查结果比较,阳性符合率100%。5例非PHPT的患者中,双核素减影显像均为阴性。结论:双核素减影显像是诊断PHPT的重要方法,尤其是定位诊断更具显著优势。
OBJECTIVE: To investigate the diagnostic advantages of 201Tl / 99mTcO-4 dual nuclide imaging in the diagnosis of primary hyperparathyroidism (PHPT). Methods: Ten patients with suspected primary hyperparathyroidism (PHPT) underwent 201Tl / 99mTcO-4 dual-neutron subtraction imaging. Among them, 5 cases of pathological diagnosis of PHPT (adenoma 3 cases, adenocarcinoma 2 cases ), Non-PHPT5 cases. Results: Among the 5 patients who were diagnosed as PHPT, 5 cases were positive for binuclear subtraction imaging. The positive coincidence rate was 100% compared with the results of pathological examination. In 5 non-PHPT patients, dual-nude subtraction imaging was negative. Conclusion: Dual-nuclide subtraction imaging is an important method for the diagnosis of PHPT, especially for the localization diagnosis.
