Synopsis

Keywords: Image acquisition: Quantification

MR spectroscopic imaging is a unique tool for tracer-free noninvasive molecular imaging utilizing the chemical shift and J-coupling effects of nuclear spins from endogenous nuclei. In recent years, a new class of MRSI methods has also emerged, which uses sparse sampling for fast imaging and model-based machine learning for denoising and image reconstruction. This talk will give an overview of the MRSI principles and state-of-the-art methods and discuss the potential of the new emerging methods.

MR spectroscopic imaging is a unique tool for tracer-free noninvasive molecular imaging utilizing the chemical shift and J-coupling effects of nuclear spins from endogenous nuclei. After several decades of development, it has become an invaluable tool for a wide range of biomedical imaging applications. State-of-the-art MRSI methods include chemical shift imaging (CSI) and echo-planar spectroscopic imaging (EPSI), which acquire and process spatially encoded spectral information using the conventional Fourier imaging theory. In recent years, a new class of MRSI methods has also emerged, which uses sparse sampling for fast imaging and model-based machine learning for denoising and image reconstruction. This talk will give an overview of the MRSI principles and state-of-the-art methods and discuss the potential of the new emerging methods.
