Positron Emission Tomography Centre

Staff Profile

Elizabeth Howell

Associate Lecturer


I'm an NHS Clinical Scientist specialising in Nuclear Medicine Medical Physics, with a sub-speciality interest in PET imaging. For those unfamiliar with the acronym PET is Positron Emission Tomography. PET involves injecting individuals with tracer amounts of anti-matter emitting radioactive medicines (radiopharmaceuticals) and using their emissions to image where they go in order to understand physiological and pathological processes in-vivo.

In my current role I'm lucky enough to be dedicated to supporting the PET-MR centre at Newcastle University. The research here is exploring new possibilities that emerge when PET is combined with simultaneous MRI (Magnetic Resonance Imaging).

My specialist knowledge and skills are focussed around using radiopharmaceuticals safely and getting the best out of PET scanning and image analysis equipment, so I work across a wide range of scientific and clinical applications of this technology.


I teach on the Scientist Training Programme (STP): MSc Clinical Science, contributing lectures and seminars to the following modules:

  • MSC8001 Introduction to Healthcare Science, Professional Practice and Clinical Leadership
  • MPY8001 Introduction to Medical Physics
  • MPY8009 Imaging with Ionising Radiation 1
  • MPY8010 Imaging with Ionising Radiation 2

In addition to contributing to the academic component of the course I support Medical Physics trainees in the Northern Training Consortium with PET related workplace based competency completion at Newcastle PET Centre.

Trainees in relevant specialities employed by the Northern Training Consortium who would like to consider undertaking the research components of the MSc at the PET-MR centre are welcome to contact me about possible projects.

In addition to my teaching here in Newcastle I was recently invited to contribute to the HSST (Higher Scientific Specialist Training) program with a specialist lecture on PET-MR delivered in collaboration with Ross Maxwell.
