چکیده
choline, glutamate and inositol (32x32 matrix) with 2-fold SENSE acceleration. Fig.3 Fully sampled PEPSI maps of non-suppressed water (64x64 matrix) and metabolite maps of NAA, creatine, choline, glutamate and inositol (32x32 matrix), acquired in 8.5 min with 0.63 cc voxel size. Fig.1 Non-water-suppressed PEPSI maps on phantom at 7 T show good reconstruction performance for up to 4-fold acceleration Fig.2 Un-accelerated (L) and 2-fold accelerated (R) in vivo spectra from central gray matter with clearly demarcated glutamate peak and LCmodel fit.

متن کاملAccelerated Proton Echo-Planar Spectroscopic Imaging Using Parallel Imaging and Compressed Sensing
INTRODUCTION: Proton Echo-Planar Spectroscopic Imaging (PEPSI) provides fast spatial-spectral encoding and has been demonstrated to map a variety of metabolites in the human brain [1,2]. Further acceleration in PEPSI can be accomplished by using parallel imaging along the phaseencoding dimension(s) [3,4]. However, the acceleration is limited by the relatively low SNR of the metabolites and g-fa...

متن کاملFast detection of diffuse axonal damage in severe traumatic brain injury: comparison of gradient-recalled echo and turbo proton echo-planar spectroscopic imaging MRI sequences.
BACKGROUND AND PURPOSE Diffuse axonal injury (DAI) is a common type of primary neuronal injury in patients with severe traumatic brain injury (TBI), and is frequently accompanied by tissue tear hemorrhage. T2-weighted gradient-recalled echo (GRE) sequences are more sensitive than T2-weighted spin-echo images for detection of hemorrhage. The purpose of this study is to compare turbo Proton Echo ...
