    High magnetic susceptibility coatings for visualisation of optical fibres on a specialised interventional MRI system

    The aim of this study was to develop methods of visualising optical fibres on MRI scans for monitoring interstitial laser therapy. Scans were performed on a specialised MRI extremity scanner at 0.17 T. Optica...

    NMR Studies of Hypoxic-Ischaemic Injury in Neonatal Brain Using Imaging and Spectroscopy

    Brain injury arising in the perinatal period leads to death or permanent and severe impairment in more than 1000 infants per year in the UK (Alberman and Botting, 1991). The aim of this work is to use nuclear ...
