９９ｍＴｃ一高锝酸钠甲状腺显像以往主要集中在静态显像，其临床价值比较局限。甲状腺血流与静态显像（双时相显像）相结合，能获得更大的信息量，可以明显地提高甲状腺疾病诊断水平。本文对１９例亚急性甲状腺炎（亚甲炎）患者进行双时相显像，分析双时相显像对亚甲炎的诊断
99mTc a pertechnetate thyroid imaging in the past mainly focused on the static imaging, its clinical value is more limited. Thyroid blood flow and static imaging (dual phase imaging) combined to get a greater amount of information, can significantly improve the diagnosis of thyroid disease. In this paper, 19 patients with subacute thyroiditis (methyleneitridi) patients underwent dual phase imaging, analysis of dual-phase imaging of the diagnosis of methyleneuria
