MAGNETIC RESONANCE IMAGING DEVICE AND DIFFUSION WEIGHTED IMAGE ACQUIRING METHOD THEREOF

摘要

PURPOSE: A magnetic resonance imaging device and a diffusion accentuation image obtaining method thereof are provided to measure accurate diffusion rates and to reduce time for obtaining an image by obtaining a diffusion accentuation image from a radial k-space. CONSTITUTION: An image having emphasized contrast between a diffusion material and a non-diffusion material is obtained as a signal reduction degree between the materials is increased when a diffusion gradient magnetic field is applied before and after the application of a 180-degree RF pulse in a spin echo pulse sequence.
