A theoretical study of the effect of experimental noise on the measurement of anisotropy in diffusion imaging
ME Bastin, PA Armitage, I Marshall - Magnetic resonance imaging, 1998 - Elsevier
Diffusion tensor imaging (DTI) is a modality known to be highly sensitive to the detrimental
effects of experimental noise. Here, using Monte Carlo simulations, we compare and contrast …

Do acute diffusion-and perfusion-weighted MRI lesions identify final infarct volume in ischemic stroke?
Background and Purpose— An acute mismatch on diffusion-weighted MRI (DWI) and
perfusion-weighted MRI (PWI) may represent the “tissue-at-risk.” It is unclear which “…
