Abstract

Background

Abbreviated-breast-MRI (abMRI) has been developed to address limitations of full-protocol-breast MRI (fpMRI)(time to acquire and report with associated cost and patient discomfort). AbMRI diagnostic-accuracy is similar to fpMRI (Geach et al. 2021) and therefore has potential for wider use in screening but to roll it out on a larger scale more readers, skilled in interpreting abMRI, would be needed. Initial evaluation has shown NHSBSP mammogram-readers could be trained to interpret abMRI with a single day of structured training (Jones et al. 2019).


Method

This study aims to evaluate the learning curve of novice readers reaching competence in abMRI interpretation. A cohort of mammogram-readers (20 novice and 17 experienced) from 6 different NHS breast screening programme units in South West England will undergo formative training and their learning curves plotted over time (diagnostic-accuracy and reading times). The variation in learning will be quantified and compared for individual readers and explore remote formative training by e-learning in this cohort.

Results

This is a trial in progress. Preliminary results will be available by October 2021 for inclusion in this presentation.

Conclusion


Impact statement

This is part of the UK FAST MRI research programme and could impact significantly on the time and costs of providing effective breast MRI in the future, with the aim of early cancer detection through screening.
