An improved radionuclide method for the diagnosis of gastroesophageal reflux and aspiration in children (milk scan).

abstract：:The concept of diffusion magnetic resonance (MR) imaging emerged in the mid-1980s, together with the first images of water diffusion in the human brain, as a way to probe tissue structure at a microscopic scale, although the images were acquired at a millimetric scale. Since then, diffusion MR imaging has become a pil...
