Dr Mary McLean

Interests

I perform magnetic resonance imaging and spectroscopy studies on patients with brain tumours (as well as tumours of other parts of the body). The aim is to improve non-invasive diagnosis and the prediction and monitoring of response to treatment. Prior to 2007 I spent nine years performing similar studies in a wide gamut of neurological and psychological disorders at the Institute of Neurology, London.
