Abstract

Diffusion‐weighted MRI is a clinically useful technique, but its utility is compromised by high sensitivity to patient motion. Use of radial‐scan data acquisition and projection reconstruction, rather than the conventional Fourier imaging method, can substantially reduce the sensitivity to global translational motion of the object. The basis of this concept and a demonstration of the technique in an animal imaging experiment are presented.
