正电子发射断层成像与微血管研究

Positron emission tomography and microvascular research

正电子发射断层成像是研究物质在人体内分布的重要手段。物质在体内的分布是借助于循环系统的运输及微血管内血液与组织器官的物质交换实现的。正电子发射断层成像和微血管的研究都围绕着物质在体内的传输与交换。将PET成像的方法应用于微血管的研究或用微血管的理论来辅助PET图像的分析都是有意义的。将介绍国外在这一领域里的重要研究进展并预测其发展前景。

Positron emission tomography （PET） plays an important role in the research of substance distribution in Human body. The distribution of substance in whole body is carried out by the transport via circulation system and exchange between blood and tissue which occurs in microvascular. Both the research of PET and of microvascular are focused on the transport and exchange of substance in human body. So it should be meaningful to apply PET image to the research of microvascular, and to use the mierovascular theory to improve on the analysis of PET image. In this article, some research in this domain are introduced, and foreground is reviewed.
