NM advisory group

NMAG consists of a panel of carefully chosen experts who advise the organisation on the development of suitable policies and strategies to support nuclear medicine practice. In addition NMAG undertakes a range of projects to facilitate the implementation of such policies.

NMAG is currently working on a number of projects, including a joint project with the Institute of Physics and Engineering in Medicine (IPEM) to identify standards for education, practice and development of nuclear medicine practitioners, guidance around the provision of nuclear medicine hybrid imaging services and a major review of the Society's nuclear medicine policy and strategies.

Sue Johnson is the SCoR Officer responsible for this group.

David Wyn Jones MSc DCR(R) DRI CRadP MSRP (Chair)

David currently leads the Nuclear Medicine service in North Wales for the Betsi Cadwaladr University Health Board. As Principal Radiographer, he is responsible for leading and developing nuclear medicine services for the region, and has responsibility for services at three acute sites, as well as the provision of PET/CT imaging for the region

After qualifying as a radiographer at the Shropshire School of Radiography in 1989, David worked in general radiography before specialising in Nuclear Medicine, undertaking the DRI at the Birmingham School of Radiography (led by Ken Holmes and Dr Keith Harding) in 1992, and later undertaking an MSc in Nuclear Medicine at Salford University with Professor Peter Hogg.

David has experience of CT and MRI also, having worked in acute and specialist hospitals, and some previous experience of University teaching, as part time lecturer at City University, London, and as a visiting lecturer and examiner for Bangor University. Former honorary posts also include Honorary Research Fellow, and Honorary Lecturer at Salford.

David is a former ARSAC committee member, having served for over 8 years, giving a radiographic perspective to the work of the committee, advising Government.

As well as contributing to the Nuclear Medicine chapters in both editions of the textbook ‘Carver & Carver - Medical Imaging’, David has published a textbook entitled ‘Practical SPECT/CT’, with Springer, bringing together international experts for the benefit of nuclear medicine practice.

David is currently completing a Professional Doctorate at Bangor University – specialising in ‘Implementation Science’ – gaining expertise and knowledge by researching into ‘why evidence does not always find its way into clinical practice’.

As well as the above, some time is also found to assist the CQC as a specialist adviser for Radiology / Nuclear medicine, undertaking regular inspection work and advising as appropriate.

David has recently served as Chair of NMAG at the SCoR for 4 years and continues to be an active advisory group member.

Key Interests: Service Development / Professional Development / Radiation Protection / Regulation / Clinical Nuclear Medicine and Research


Dr Penny Delf D.MedImg MSc PgC(RNI) BSc(Hons) DCR(R) SFHEA

Originally trained as a Diagnostic Radiographer at the Westminster Hospital, practising in London and southern counties, Penny subsequently gained extensive experience within Higher Education as a senior academic, contributing her knowledge and insight to the delivery of professional programmes and at a strategic level.

She is a Senior Fellow of the Higher Education Academy and an external examiner for undergraduate and postgraduate programmes at Birmingham City University and the University of Hertfordshire respectively. She has authored various publications, undertaken conference presentations at local and national level, and peer reviews for two professional journals.

In 2012, she was awarded a Doctorate in Medical Imaging following a programme of research into “The design, implementation and effectiveness of a sole eLearning module to prepare non-medical healthcare practitioners to report radionuclide bone scans”. This work has informed her current research, which includes the promotion of ongoing professional education to meet workforce needs, through the development of sustainable, interactive and adaptive eLearning technologies.

She maintains a keen interest in current professional issues through her involvement as Vice Chair of the Nuclear Medicine Advisory Group and as Treasurer for the Association of Paediatric Radiographers. She also maintains her role a registered assessor for the Society and College of Radiographers involved in the accreditation and approval of educational courses and advanced practitioner applications.

Dr Han is a member in SIGN guidelines for lung cancer 2014, the British Nuclear Medicine Society Education Committee, and the UK Nuclear Medicine Specialist Training Committee. He also contributes to FRCR IIA GI module lectures and IIB tutorials in the West of Scotland Radiology Training Scheme.





Mark McDade MSc RSci IPEM

Mark currently works as an Advanced Specialist Clinical Technologist in Scotland for Greater Glasgow and Clyde Health Board. He is jointly responsible for delivering and developing Nuclear Cardiology services across the west coast.

Mark has a broad background, having worked in Radiotherapy, Cardiothoracic Theaters, Bio-Engineering and general Nuclear Medicine, before specialising in Nuclear Cardiology. As a registered Clinical Physiologist he has an interest in ECG and instructs health care professionals in 12 lead reporting. He is trained in Advanced Life Support and is an Immediate Life Support instructor.

Marks role as member of Nuclear Medicine Advisory Group for the Institute of Physics and Engineering in Medicine allows him to contribute at a national level. Enabling him to offer advice and promote perspectives from Clinical Technologists.

Key Interests: Professional Development / Service Development / Cardiac Imaging / Teaching and Training.


Dr John Thompson

I am a Senior Radiographer with over 10 years experience, currently working in a Nuclear Medicine department in a small district general hospital. I am currently on a 2-day secondment at the University of Salford where I have been heavily involved with research. I have recently completed a PhD, where much of the focus was into the value of the low-resolution CT images acquired for attenuation correction in myocardial perfusion imaging. My main area of expertise is observer performance , where I have developed skills in free-response receiver operating characteristic (FROC) analysis.






Simon King

Simon is a Programme Leader and Senior Lecturer within the Faculty of Health and Applied Sciences at the University of the rest of England, Bristol. Alongside various teaching and facilitation responsibilities on the undergraduate Diagnostic Imaging (Radiography) programme, Simon is currently responsible for the management and provision of an MSc programme in Nuclear Medicine which is delivered as a ‘distance learning’ package to UK and international students.

Recent work has concentrated on the development and delivery of Continuous Professional Development (CPD) and post graduate education, utilising a variety of teaching models and innovative Technology Enhanced Learning (TEL) solutions.

He is a Fellow of The Higher Education Academy in recognition of attainment against the UK Professional Standards Framework for teaching and learning support in higher education, and also works alongside the MSc Medical Imaging programme team at Trinity College, Dublin, as their External Examiner. Simon has recently embarked on a PhD award at the University of the West of England and key interests include Patient Care, Hybrid Imaging and Technology Enhanced Learning
