White matter fiber tracking using diffusion magnetic resonance imaging (dMRI) provides a
noninvasive approach to map brain connections, but improving anatomical accuracy has …

Artifacts in magnetic resonance (MR) imaging result from the complex interaction of
contemporary imager subsystems, including the main magnet, gradient coils, radiofrequency …

Magnetic resonance diffusion imaging is potentially an important tool for the noninvasive
characterization of normal and pathological tissue. The technique, however, is prone to a …

This study compares the measured activation volumes in motor cortex as well as the
fluctuation noise and off‐resonance characteristics for 1‐, 2‐, and 4‐shot spiral gradient …

Purpose To reduce the sensitivity of echo‐planar imaging (EPI) auto‐calibration signal
(ACS) data to patient respiration and motion to improve the image quality and temporal …

An algorithm is described for reducing ghost artifacts in echo planar imaging (EPI) using
phase corrections derived from images reconstructed using only even or odd k‐space lines …

The combination of parallel imaging with partial Fourier acquisition has greatly improved the
performance of diffusion‐weighted single‐shot EPI and is the preferred method for …

Optical imaging studies have provided evidence of an initial increase in deoxyhemoglobin
following the onset of neuronal stimulation/activation and demonstrated that this initial …

Ultra‐high‐field MRI provides large increases in signal‐to‐noise ratio (SNR) as well as
enhancement of several contrast mechanisms in both structural and functional imaging …

Geometric distortions and poor image resolution are well known shortcomings of single‐shot
echo‐planar imaging (ss‐EPI). Yet, due to the motion immunity of ss‐EPI, it remains the most …
