Title: Technical, Practical and Operational issues in MRI-PET

Date: 26 November 2012 (Monday)

Time: 1 - 2 pm

Place: Roberts 106


The Siemens mMR Biograph is the first commercially available clinical simultaneous PET-MRI scanner. It was installed at the UCH-Macmillan Cancer Centre in February 2012 and was commissioned on the 2 April 2012 for the opening of the new Cancer Centre. Since then we have performed over 180 investigations and have several research studies currently running. The lunchtime seminar will be split into three areas. Firstly I will elaborate on the novel technical and engineering aspects of the scanner. Secondly the operational aspects of the 2 imaging modalities will be discussed. Finally I will elaborate on the practical aspects of the investigations available, with a discussion of the potential areas of physics research in this latest area of medical imaging.


Doctor Anna Barnes graduated in physics and astronomy in 1993 and joined the Scottish-NHS Medical Physics Training Scheme. Alongside her professional training as a clinical scientist she obtained her MSc and PhD in nuclear medicine neuroimaging techniques and statistical analysis applied to epilepsy, dementia and schizophrenia. Anna then took a 2 year post-doc fellowship at the Feinstein Inst. for medical research (affiliated to NYU medical school) with David Eidelberg, specialist in PET imaging of movement disorders. After a brief consultancy with GE Healthcare in Amersham, working on analysis software for new neuroimaging tracers, she took a staff scientist post at Columbia University, NY with Prof Joy Hirsch working with psychologists to develop fMRI paradigms for exploring a range of cognitive functions. Doctor Barnes’ previous post before joining UCLH Institute of Nuclear Medicine was as a research associate at Ed Bullmore’s Brain Mapping Unit (BMU) at the University of Cambridge where she worked for 5 years. The BMU specialises in using the mathematics of complex systems and MRI to understand the pathophysiology of mental illness. During this time she published papers on fractal analysis of cognitive function and the use of MRI endophynotypes for “at risk for schizophrenia” genes.
