Most brain imaging researchers would agree with the assertion that functional MRI (fMRI) is
progressing. Since fMRI began in 1991, the number of people, papers, and abstracts related …

Background Magnetic field inhomogeneity in magnetic resonance imaging (MRI) is caused
by the inherent properties of the main magnet, external ferromagnetic components …

Single shot echo‐planar imaging (EPI) sequences are currently the most commonly used
sequences for diffusion‐weighted imaging (DWI) and functional magnetic resonance …

Purpose Macroscopic magnetic field inhomogeneities adversely affect different aspects of
MRI images. In quantitative MRI when the goal is to quantify biological tissue parameters …

The orbitofrontal cortex comprises the ventral surface of the frontal lobe, and is critical for
functions ranging from olfaction and emotion to learning and behavioral flexibility. Since the …

R_2^∗ab mapping has important applications in MRI, including functional imaging, tracking
of super‐paramagnetic particles, and measurement of tissue iron levels. However, R_2^∗ab …

A technique suitable for diffusion tensor imaging (DTI) at high field strengths is presented in
this work. The method is based on a periodically rotated overlapping parallel lines with …

Dynamic alteration of shim settings during a multi-slice imaging experiment can improve
static magnetic-field homogeneity over extended volumes. In this report, a pre-emphasized …

Mammalian models, and mouse studies in particular, play a central role in our
understanding of placental development. Magnetic resonance imaging (MRI) could be a …

Accelerated parallel imaging (PI) techniques have recently been applied to functional
imaging experiments of the human brain in order to improve the performance of commonly …
