Cranial Neurovasculopathy Research Programme

Together with clinical, neurological and dental partners, the team is experienced in using high-resolution heavily T2-weighted 3D MRI, multiband accelerated RESOLVE DTI and MR neurography in the evaluation of neurovascular conflicts of the facial and trigeminal nerves, and neuropathies affecting the extracranial trigeminal nerve and brachial and lumbosacral plexopathies.
