high gradient magnetic separation techniques for kids in gambia

Diffusionweighted mri, or dwi, is a fast, quantitative technique that is easily integrated into a morphological mr acquisition. the ability of dwi to aid in detecting multifocal skeletal pathology and in characterizing tissue cellularity to a level beyond that possible with other techniques makes it a niche component of multiparametric mr imaging of the skeleton. besides its role in disease.
