## Abstract The quantification of blood oxygenationβlevel dependent (BOLD) functional MRI (fMRI) signals is closely related to cerebral blood flow (CBF) change; therefore, understanding the exact relationship between BOLD and CBF changes on a pixelβbyβpixel basis is fundamental. In this study, quan
The increased blood oxygenation level-dependent contrast-to-noise ratio at ultrahigh field (7 T) has been exploited in a comparison of the spatial location and strength of activation in high-resolution (1.5 mm isotropic) gradient echo (GE) and spin echo (SE), echo planar imaging data acquired during
Known specialized properties of the human visual cortex have been used to investigate the role of spatial resolution on fMRI using blood oxygenation level dependent (BOLD) echo-planar MRI at 3.0 tesla. The magnitude of BOLD signal changes has been examined at low (3.1Ο« 3.1Ο« 3.0 mm 3 ) and high (0.8Ο«
