| 内容記述 | Recently, diffusion-weighted (DW) fMRI signal changes have been reported to increase at high diffusion-weightings (b-values) [1-4]. It has been suggested that DW-fMRI signal courses might reflect vessel-size specific extravascular (EV) BOLD [1], persistent blood signal and changes in cerebral blood volume [2,3], or cell swelling directly linked to brain activation [4]. Berfication of any these mechanismsmight lead to a significantly enhanced understanding of the functional response. The aim of this study was to investigate the signal change dependency over a relatively broad range of imaging parameters. The experiments were performed on a-chloralose anaesthetised rats at 7 T using electrical forepaw stimulation with b-values in the range O-200 s/mm2 and echo-times of 30, 60 and 90 ms. | |||||
