Synopsis

Keywords: Spinal Cord, New Trajectories & Spatial Encoding Methods, Rosette Imaging, Compressed Sensing.MRI is very useful to investigate spinal cord pathologies non-invasively. However, signal to noise ratio (SNR), spatial resolution and motion artifacts are some of the main challenges in spinal cord MRI. Ultra high field MRI such as 7T, can improve the SNR enabling high spatial resolution. The inherent property of low susceptibility to motion of non-Cartesian imaging technique such as Rosette, can improve the motion related artifacts. So the goal of this study was to develop a technique for high-resolution spinal cord imaging at 7T using Rosette MRI.
