The temperature sensitivity of the relaxation parameters represents a major issue in post-mortem MRI due to the passive cooling of the deceased. This study proposes a real-time non-invasive temperature correction method of MR neuroimaging parameters based on an MRI compatible forehead temperature probe. The observed significant linear relations between the forehead temperature and the relaxation times indicate that this real-time non-invasive temperature correction method is suitable for in situ post mortem MR neuroimaging.
