    Estimation of postmortem metabolic changes in porcine brain tissue using 1H-MR spectroscopy—preliminary results

    To investigate the potential for estimating the time since death by monitoring the evolution of different metabolites in brain tissue by 1H-MRS, an animal model using pig heads was established. The maximum examin...
