~(99)锝—葡庚糖酸盐(~(99)Tc—glucoheptonate)作为脑瘤显像剂是1976年 Wa-xman 等报道,随后关于此药的临床应用,国外又有一些报告,并和~(99)TcO_4~-、~(99)Tc—DTPA 做了对比研究,均认为在脑瘤显像方面,~(99)Tc—GH 较上两药优越。它的优点是瘤灶吸收较多,通过肾脏排出较快,因而人体本底较低,提高了瘤/脑比值,瘤灶易于显示和清晰;此药还有不需封闭脉络丛和甲状腺,标记简便快速可做成半成品药盒一步法标记等优点。鉴于国内尚无此药生产和应用,我们经过一年来的调查研究和
~ (99) Tc-glucoheptonate (~ (99) Tc-glucoheptonate) as a brain tumor imaging agent was reported by Wa-xman et al in 1976. Then there are some reports about the clinical application of this drug in foreign countries. And (99) TcO_4 ~ -, ~ (99) Tc-DTPA were compared, all that in brain imaging, ~ (99) Tc-GH superior to the two drugs. It has the advantage of tumor absorption more through the kidneys faster discharge, and thus lower the human body, improve the tumor / brain ratio, the tumor is easy to show and clear; this drug also does not need to close the choroid plexus and thyroid, mark Simple and quick can be made of semi-finished products kit one-step mark and so on. In view of the fact that there is no such drug production and application in our country, after a year of investigation and research
