ABSTRACT
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 microvascular theory to improve on the analysis of PET image. In this article, some research in this domain are introduced, and foreground is reviewed.
ABSTRACT
0.9). Conclusions CT perfusion imaging could quantify the hepatic blood flow.The accuracy is similar to electromagnetic flowmeter,and it could effectively reflect physiological or pathological hemodynamies of liver.CT perfusion is noninvasive,high reproducible and convenient,which could be widely used in clinical practice.
