内容記述タイプ | Abstract | |||||
内容記述 | It has been suggested that the BOLD effect contributes to heavily diffusion-weighted (DW) fMRI signal changes. The BOLD effect is usually interpreted as a change in transverse relaxation rate (deltaR2). In this study, deltaR2 during visual stimulation (VS) and hypercapnia (HC) DW fMRI experiments was estimated using a multiple spin-echo EPI acquisitions after motion-probing gradients. deltaR2 showed dependence on b-value during VS, but not during HC. The results suggest that deltaR2 at high b-value may demonstrate a higher sensitivity to neuronal activation than at lower b-values. | |||||
