Temporal interleaving artifacts in spiral MRSI: characterization and retrospective correction
Antoine Na{ë}gel, Magalie Viallon, Thomas Troalen +6
Purpose: In Spiral Magnetic Resonance Spectroscopic Imaging (MRSI), achieving suitable spatio-temporal resolutions requires interleaving. Sampling inconsistencies occurring between…
Magnetic Resonance Imaging Virtual Liver Biopsy Using Radiomics Analysis for the Assessment of Chronic Liver Disease
Jiqing Huang, Benjamin Leporq, Valérie Hervieu +4
Objectives: The role of advanced diffusion-weighted imaging (DWI) in chronic liver disease (CLD) has not been fully studied. Chronic liver disease (CLD) is a progressive deteriorat…
Linking Fluorescence Spectroscopy and 31P MRS in NADH Phantoms
Giorgi Asatiani, Arthur Gautheron, Laurent Mahieu-Williame +2
Glioblastoma exhibits significant metabolic alterations, making tracking energy metabolism important for its characterization. This could be crucial for glioblastoma resection in n…
Validation of apparent intra-and extra-myocellular lipid content indicator using spiral spectroscopic imaging at 3T
Antoine Naëgel, Magalie Viallon, Jabrane Karkouri +3
This work presents a fast and simple method based on spiral MRSI for mapping the IMCL and EMCL apparent content, which is a challenging task and it compares this indicator to class…
Computational Reproducibility in Metabolite Quantification Applied to Short Echo Time in Vivo MR Spectroscopy
Gaël Vila, Axel Bonnet, Fabien Chauveau +4
In vivo metabolite quantification by short echo time MR spectroscopy is a challenge for which various methods have been proposed. In this study, the reproducibility of quantificati…
Magnetic Resonance Spectroscopy Quantification using Deep Learning
Nima Hatami, Michaël Sdika, Hélène Ratiney
Magnetic resonance spectroscopy (MRS) is an important technique in biomedical research and it has the unique capability to give a non-invasive access to the biochemical content (me…
Optimal control theory for applications in magnetic resonance imaging
E. Van-Reeth, H. Ratiney, M. Lapert +2
We apply innovative mathematical tools coming from optimal control theory to improve theoretical and experimental techniques in Magnetic Resonance Imaging (MRI). This approach allo…
