Nuclear Medicine & Molecular Imaging Advisory Group (NMMAG)

The field of nuclear medicine is developing and expanding with hybrid imaging now an increasing part of standard clinical practices for certain groups of patients.

Molecular imaging and gene based therapies will expand nuclear medicine yet further.

Nuclear medicine practice faces many challenges including workforce, education, regulation and security of supply of radioisotopes for imaging.

The Nuclear Medicine and Molecular Imaging Advisory Group (NMMAG) will support and encourage education in Nuclear Medicine and promote educational programmes in the field by:

  • Providing information and advice to support the Society And College Of Radiographers (SCoR) in strategy development
  • Promoting SCoR policies, strategies and publications within the context of nuclear medicine to the benefit of services, practitioners and patients
  • Promoting membership of the SoR by nuclear medicine practitioners enabling practitioners and services to benefit from SCoR’s established leadership in medical imaging, radiation therapy and oncology.
  • Delivering an annual work plan that supports the aims of the SoR about nuclear medicine and molecular imaging.

The spectrum of nuclear medicine practice encompasses imaging, hybrid techniques, therapy/treatment, and in-vitro studies.

David Williams David started his Radiography career at the Royal Naval Hospital Haslar in Gosport and had the unique distinction of being the last radiographer to achieve the DCR(R) at the Royal Naval School of Radiography, before it became the Tri-Service school and moved to Woolwich.
After a mixed career he was the lead for the Specials examinations at Haslar when he was offered the opportunity to work with the Army at Queen Elizabeth Military Hospital in Woolwich, during which time he completed the DRNI at Guy’s Hospital.
Returning to the Royal Naval Hospital Haslar he commenced his Masters Degree in Nuclear Medicine at Portsmouth University.  During this period, he was mainly involved in the Specials and Angiography at Haslar, with short spells in Nuclear Medicine, before taking redundancy under the “Options for Change” programme. He completed his MSc as a civilian.
At this point exploring his options, he took a one month locum contract with Portsmouth Hospitals NHS Trust to work in Nuclear Medicine and is still there some 21 years later.
He studied for his Professional Doctorate at Portsmouth University, and was awarded a PGD in Advanced Medical Research when he had to leave the course due to personal issues.
He has the privilege of being the Superintendent Radiographer for Nuclear Medicine  at Portsmouth hospitals, a post he has held since 2010.

He also now holds the distinction of being the only Nuclear Medicine professional trained by the UK Armed Forces and still practicing.
He has previously been a member of  the Molecular Imaging specialist group of the British Institute of Radiology.
His present interests are across the whole of Nuclear Medicine, but he has a special interest  in the changes occurring in Nuclear medicine and how these can be addressed to ensure a secure future for the profession.
