Physiological origin of low‐frequency drift in blood oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI)
We investigated the biophysical mechanism of low‐frequency drift in blood‐oxygen‐level‐dependent (BOLD) functional magnetic resonance imaging (fMRI) (0.00–0.01 Hz), by exploring its spatialExpand

BOLD fMRI using a modified HASTE sequence
TLDR
A modified half Fourier acquisition single-shot TSE (mHASTE) sequence has been developed with a three-fold GRAPPA to improve temporal resolution as well as a preparation time to enhance BOLD sensitivity. Expand

Feasibility of high temporal resolution breast DCE-MRI using compressed sensing theory.
TLDR
We investigate the feasibility of using reference image based compressed sensing (RICS) technique in DCE-MRI of the breast for improving temporal resolution without degrading the spatial resolution. Expand
