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….
