| 内容記述 | Gadolinium (Gd) based dynamic susceptibility contrast (DSC) agents allow brain perfusion NMR images in both animal and human [1,2,3,4]. It is not easy to model the arterial input function (AIF) in small animals because of the small ratio of artery to tissue in a voxel. Hence, cerebral blood flow (CBF) values estimated from DSC images can be inaccurate. As an alternative, the maximum value of the logarithmic signal ratio (maxDELTA R2*) is occasionally used as an indicator of the CBF in the rat brain [3,4]. To investigate the accuracy of CBF indicated by maxDELTA R2* in the ischemic rat brain, a comparison of the CBF values obtained with continuous arterial spin labeling (CASL) and maxDELTA R2* was performed in an ischemic rat model. | |||||
