WebDiffusion is a three-dimensional process, and molecular mobility in tissues might not be the same in all directions. Diffusion anisotropy was observed at the end of the 1980s in brain white matter, where it reflects the specific organization into bundles of myelinated axonal fibres running in parallel. WebFocal nodular hyperplasia of the liver: diffusion-weighted magnetic resonance imaging characteristics using high b values Focal nodular hyperplasias show a wide range of morphological features at DWMRI using high b values. Further studies are needed to fully investigate as to what extent normalized ADC may result in better lesion characterization.
