Simulating SRSLY: Sensitivity Resolved SubvoxeL sepctroscopY

Abstract

peer reviewedMagnetic resonance spectroscopy employs localization in an approximately rectangular voxel, which commonly includes contributions from various tissues due to non-rectangular in-vivo tissues geometry. The suggested technique aims to resolve spectral contribution from different spatially distinct regions based on multichannel data, smilar to the imaging Sensitivity Encoding technique. Simulations are performed using spectral data acquired on a phantom and multichannel coil sensitivity profiles. Simulations show feasibility of the suggested spectral separation technique and demonstrate limitations related to chemical shift displacement. Real data does not yet show full spectral separation of the components
