Abstract Introduction Women with mammographically dense breasts have an increased risk of breast cancer. Dense breasts can limit detection of small breast lesions due to overlapping fibroglandular tissue. BRAID is a randomised, multi-centre UK study assessing the impact of supplementary imaging, including abbreviated breast MRI (ABB-MRI), in detection of breast cancer in women aged 50-70 years with dense breasts. ABB-MRI is a shorter protocol breast MRI, allowing much faster acquisition times. The aim of this study is to review the feasibility of introducing ABB-MRI into the NHS setting as a part of a research trial.

Protocol ABB-MRI is performed on a 1.5 tesla MRI scanner. Sequences obtained include a 2 mm axial T2 weighted sequence, a dual echo (Dixon water/fat separation) 3D DCE acquisition consisting of one pre- and two post-contrast images with generation of post-contrast subtracted images and post-processed MIP images.

Scheduling ABB-MRIs are performed on a dedicated breast MRI list. Participants arrive 30 minutes prior to appointment time with pre-filled safety questionnaire. ABB-MRIs are scheduled for a 20-minute appointment slot, allowing 10 women to be scanned in a 3-hour session. Specific roles are allocated to staff members.

Improving Efficiency of ABB-MRI in the UK Challenges encountered are similar to those encountered with FDP: IV cannulation, BMI and claustrophobia. Dedicated MR sessions with standard contrast doses and prefilled safety questionnaires help improve efficiency of sessions and allow examination times under 15 minutes.
