MR Spectroscopy 1H CSI JobAid

MR Spectroscopy 1H CSI syngo.via syngo.MR Spectroscopy is a post-processing application to analyze and evaluate MR Spectroscopy 1H datasets. It provides evaluation of MR Single Voxel Spectroscopy (SVS) and MR Chemical Shift Imaging (CSI) data with workflow guidance to support the diagnostic process. A novel fit-algorithm reduces the need for manual data processing and offers the user reproducible evaluation results. Info: syngo.MR Spectroscopy doesn’t support the following image types for evaluation  Distortion-corrected images  Images with different frames of reference (e.g., images acquired with different table positions 1.
