Eloquent brain function emerges from the coordinated activity of multiple cortical and subcortical brain regions; the white matter defines a supporting network for the efficient transfer of information of these…
Diffusion based imaging strategies is sensitive to more subtle age-related changes in white matter integrity, and these methods may enable the differentiation of normal adult aging from mild cognitive impairment…
The pattern of evolving hematomas on conventional magnetic resonance imaging (MRI) is well documented but remains somewhat complex, and its interpretation is further complicated by diffusion weighted imaging (DWI). T2…
Physics In diffusion imaging, directional diffusion gradients are applied to a T2-weighted (spin-echo) echo-planar imaging (EPI) sequence before and after a 180-degree refocusing pulse. Water protons moving freely through these…
Diffusion weighted imaging (DWI) is the method of choice for the detection of spinal cord infarction. Diffusion tensor imaging (DTI) can be helpful for differentiating ependymoma from astrocytoma in adults….

Diffusion weighted imaging is an important tool for evaluating brain tumors and can be used for diagnosis, follow-up, and determining the prognosis. Apparent diffusion coefficients (ADCs) are inversely correlated with…
Temporal maturation of the major white matter tracts follows a nonlinear pattern, with the most significant growth during the first year of life, followed by a slower pace in the…
