摘要
应用彩超对67例住院术前病人进行双侧甲状腺上、下动脉血流量的测定。其中10例正常甲状腺,8例甲亢,18例结节性甲状腺肿,16例甲状腺腺瘤,10例甲状腺癌,5例甲状腺炎。结果表明:甲亢的血流量最大,其它疾病组的血流量也比正常组高(P<0.005)。孤立肿瘤的肿瘤侧的血流量比非肿瘤侧的血流量高(P<05)。恶性肿瘤的肿瘤侧血流量与良性肿瘤的肿瘤侧血流量无显著性差异(P>0.05),而其非肿瘤侧的血流量出现显著性差异(P<0.05),恶性肿瘤的非肿瘤侧甲状腺组织血流量大,因而肿瘤侧血流量与非肿瘤侧血流量之比(R)具有重要意义。此血流比(R)本组有临界常数,其数值为1.6。当 R>1.6时其良性的可能性大。当 R<1.6时恶性的可能性大。其整体血流比(R)及临界常数目前国内外未见报告。
As a result,the ratio of BFV between tumor side and normal side was very important.There was a critical constant(R)in the tumor group,with its value of 1.6,the tumor might be benign and when R<1.6 t might be malignant.In addition,there has been no report on the ratio of the whole blood flow volume and on the critical contant in the world.
