Abstract

Xenon and iodine enhanced dynamic computerized tomography (CT) have been used experimentally to obtain both qualitative and quantitative information on local cerebral blood flow in both normal and infarcted tissue. Direct comparisons between Xenon enhancement, iodine enhancement and pathological findings demonstrate significant differences between results derived from each of the 2 in vivo techniques. While iodine enhanced dynamic CT yields valuable information concerning the patency and density of vasculature, xenon enhanced studies can provide highly focal information on cerebral tissue perfusion.

摘要

氙气和碘增强动态计算机断层扫描（CT）已被用于实验，以获取正常组织和梗死组织中局部脑血流量的定性和定量信息。氙气增强、碘增强与病理结果之间的直接比较表明，这两种体内技术所得结果存在显著差异。虽然碘增强动态CT可提供有关血管通畅性和密度的有价值信息，但氙气增强研究能提供关于脑组织灌注的高度局部化信息。
