Diffusion MRI

Diffusion MRI measures the diffusion of water molecules in biological tissues. In an isotropic medium (inside a glass of water for example) water molecules naturally move randomly according to turbulence and Brownian motion. In biological tissues however, where the Reynold’s number is low enough for flows to be laminar, the diffusion may be anisotropic. For […]

Diffusion Weighted MR Image

Diffusion Weighted MR ImageLung CancerDiffusion weighted imaging provides a new way to evaluate liver lesions.These images are obtained during a single breath hold using a single shot spin-echo EPI sequence.DWI assesses areas of altered microscopic water migration. B values for liver DWI is 20. Number of View: 6344
