Recent developments in the use of magnetic resonance (MR) to measure and image
diffusion and blood microcirculation (“perfusion”) are summarized. After a brief description of …

We review the current status of liquid flow velocity studies by pulsed nuclear magnetic
resonance (NMR). NMR is a non-invasive method that is most sensitive to protons, so that …

The optimization of acquisition parameters for precise measurement of diffusion in
anisotropic systems is described. First, an algorithm is presented that minimizes the bias …

The recently established single-shot technique of echo-planar imaging of intravoxel
incoherent motion (IVIM) for determining and imaging the variations of microscopic motions …

An improved echo planar high-speed imaging technique using spiral scan is presented and
experimental advantages are discussed. This proposed spiral-scan echo planar imaging …

The accuracy of single diffusion tensor MRI (DT‐MRI) measurements depends upon the
encoding scheme used. In this study, the diffusion tensor accuracy of several strategies for …

PURPOSE MR diffusion imaging was performed to investigate changes in water diffusion in
patients with cerebral infarction. METHODS Diffusion maps of the apparent diffusion …

We calculate the effects of subvoxel variations in magnetic susceptibility on MR image
intensity for spin‐echo (SE) and gradient‐echo (GE) experiments for a range of microscopic …

After a decade of evolution and application of diffusion imaging, a large body of literature
has been accumulated. It is in this context that the accuracy and precision of diffusion …

An explicit treatment of electronic polarization is critically important to accurate simulations of
highly charged or interfacial systems. Compared to the iterative self-consistent field (SCF) …
