目的：为明确９９ｍＴｃ血流和静态双时相显像对各种常见甲状腺疾病特别是桥本氏病的诊断价值。方法：对正常人５１０例和７种甲状腺疾病患者１４６４例进行了研究。结果：甲状腺血流和静态摄取量通常可直接反应甲状腺功能高低，除伴有甲亢外，桥本氏病者多数为血流增多而静态摄取量不增多且分布不均匀。但对于癌只能提示可能性。结论：甲状腺双时相显像比以往单纯静态显像明显提高了鉴别诊断价值，特别是可对桥本氏病的诊断提供帮助。建议列为常规应用。
Objective: To clarify the diagnostic value of 99mTc flow and static dual-phase imaging for various common thyroid diseases, especially Hashimoto’s disease. Methods: A total of 5104 normal subjects and 764 thyroid disease patients were studied. Results: Thyroid blood flow and static uptake usually directly reflect the thyroid function. In addition to Hyperthyroidism, most of Hashimoto’s patients have increased blood flow and their static uptake does not increase and their distribution is not uniform. But for cancer can only suggest the possibility. Conclusion: Double thyroid imaging can obviously improve the differential diagnosis value compared with pure static imaging in the past, especially it can help to diagnose Hashimoto’s disease. Recommended as a general application.
