Towards Routine Clinical Use of Radial Stack-of-Stars 3D Gradient-Echo Sequences for Reducing Motion Sensitivity

Abstract

Almost all clinically established MR imaging techniques today use Cartesian acquisitions of k-space in which the Fourier space of the imaged body is sampled along parallel lines. Cartesian sampling was widely accepted as the standard technique after its first description by Ernst’s group in 1975 (1) because parallel-line acquisitions can be implemented with low accuracy requirements for the gradient timing and INTRODUCTION �Received; April 2, 2014�Revised; May 28, 2014 �Accepted; May 29, 2014 Corresponding author : Kai Tobias Block, Ph.D. Bernard and Irene Schwartz Center for Biomedical Imaging, Department of Radiology, New York University School of Medicine, 660 First Avenue, New York, NY 10016, USA.
