Comparative evaluation of zoomed and parallel diffusion-weighted imaging: A phantom study

Akiyoshi Iwase, Yasuo Takatsu, Naoki Ohno, Azusa Kitao et autres

Objectives: Single-shot echo-planar imaging sequences with parallel imaging are widely used for diffusion-weighted imaging (DWI). However, when small fields of view and higher phase-encoding reduction ratios (PRs) are applied, image quality may deteriorate because of imperfections in the unfolding process of parallel …

Motion‐Compensated Diffusion Imaging With Phase‐Contrast for Robust Quantification of Regional Cerebral Blood Flow

Naoki Ohno, Tosiaki Miyati, Genki Nambu, Yu Ueda et autres

PURPOSE: To develop and evaluate a motion-compensated diffusion imaging with phase-contrast (MC-DIP) technique for mitigating errors in regional cerebral blood flow (rCBF) quantification caused by physiological brain motion. METHODS: Diffusion-weighted images were acquired in 11 healthy volunteers on a 3.0 T MRI …
