BACKGROUND: There are many protocol variations in the whole-body 75SeHCAT retention test [whole-body retention (WBR)] for investigation of bile acid diarrhoea. The time between capsule consumption and first count, however, is widely taken, without debate, to be 3 h. In the Covid-19 era, it is desirable to limit the time patients spend in the department. We, therefore, questioned the need for a 3 h interval between capsule administration and the initial count. METHODS: Using an uncollimated gamma camera, whole-body counting was performed at 5, 30 and 180 min after capsule ingestion in 24 patients with chronic diarrhoea. Geometric mean was taken of counts acquired from posterior and anterior projections. WBR was expressed as the ratio of 7 day-to-initial whole-body counts (%) to give WBR5, WBR30 and WBR180. A small meal was given at 60 min after capsule ingestion. RESULTS: There was a close correlation between WBR30 and WBR180 (y = 1.0x - 0.29%; r = 0.99). For WBR180 values of

This article summarises the proceedings of a continuing professional development session on the use of intravenous contrast media in hybrid imaging for radiographers, technologists, and nurses. The session was jointly organised by the British Nuclear Medicine Society Radiographer, Technologist, and Nurses Group and the Society of Radiographers at the 47th Annual Spring Meeting of the British Nuclear Medicine Society held in Oxford, UK, on 1-3 April 2019.

Background After the success of PET/CT as a clinical diagnostic tool, the introduction of PET/MRI is a natural development aimed at further improving combined diagnostic imaging and reduced ionising radiation dose for half-body imaging. As with PET and CT, the combination of PET and MRI presents a series of issues that need to be addressed regarding workforce training and education. At present, there is a lack of agreement over the competencies, training requirements and educational pathways needed for PET/MRI operation. In the UK, following the establishment of the MR-PET imaging network, a task force was created to investigate the status of the workforce training, identify gaps and make recommendations regarding staff training. To do this, we ran a national survey on the status of the workforce training and the local practices across the UK’s seven PET/MRI sites, reviewed the literature, and convened a panel of experts, to assess all the evidence and make recommendations regarding PET/MRI competencies and training of nuclear medicine technologists and radiographers. Results There is limited literature available specifically on competencies and training for technologists and radiographers. The recommendations on the topic needed revisiting and adapting to the UK MR-PET network. The online survey confirmed the need for developing PET/MRI competencies and training pathways. Local organisational structures and practices were shared across the seven sites, based on models derived from experience outside the UK. The panel of experts agreed on the need for PET/MRI competencies and training strategies. Professional organisations started collaborative discussions with partners from both Nuclear Medicine and Radiography to set training priorities. Multidisciplinary collaboration and partnership were suggested as a key to a successful implementation of competencies and training. Conclusions The report identified the need for establishing competencies for the PET/MRI workforce, particularly for technologists and radiographers. It also helped defining these competencies as well as identifying the demand for bespoke training and the development of local and national courses to be implemented to fulfil this new training need.
