Artifacts in Diffusion MRI
This chapter focuses on artifacts that are relevant for diffusion • imaging studies of the brain in a clinical research setting. For typical clinical studies, the most relevant sources of “physi • ological noise” artifacts are subject motion and cardiac pulsation, and the most common sources of “system-related artifacts” are eddy current distortions. Artifacts not only increase the variability...
متن کاملArtifacts and pitfalls in diffusion MRI.
Although over the last 20 years diffusion MRI has become an established technique with a great impact on health care and neurosciences, like any other MRI technique it remains subject to artifacts and pitfalls. In addition to common MRI artifacts, there are specific problems that one may encounter when using MRI scanner gradient hardware for diffusion MRI, especially in terms of eddy currents a...
متن کاملUltrastructural Cytochemistry
Selective extraction of specific cell components by enzyme or acid hydrolysis is possible from ultrathin sections for electron microscopy and parallel 2 micro sections for light microscopy of tissues fixed in formalin and embedded in a water-soluble polyepoxide, product X133/2097. Normal rat tissues fixed 15 minutes in formalin at 3 degrees C are more rapidly digested by proteinases than those ...
متن کاملReduction of Aliasing Artifacts in Diffusion-Weighted PROPELLER Imaging
Introduction Diffusion imaging is typically performed in axial planes. This is largely due to its reliance on single-shot echo-planar imaging (EPI) which suffers from increased image distortion in sagittal and coronal planes because of concomitant gradient fields [1-2], especially with strong gradients and/or at relatively low B0-fields (including 1.5T). Diffusion-weighted (DW) imaging in non-a...
متن کامل"Pitfalls in Diffusion: What Artifacts Should I Worry About?"
This presentation covers the sources of many common diffusion image artifacts. Some of these arise from the limitations of single-shot echoplanar imaging (EPI), including low spatial resolution, blurring effects of T2* decay and T2 decay occurring during image readout, and sensitivity to artifacts due to Nyquist ghosting, chemical shift, magnetic field inhomogeneity, and local susceptibility ef...
