FAST MRI Research Team

The FAST MRI Programme has been developed by a multidisciplinary team of collaborating clinicians, academics and members of the public across the UK, led by North Bristol NHS Trust. Together the FAST MRI team bring a wealth of experience in imaging, research, science and breast cancer screening and treatment.


Early breast cancer detection and diagnosis saves lives. The NHS Breast Screening Programme offers women aged 50-70 years a mammogram every 3 years. By detecting breast cancers before they can be seen or felt, breast screening already saves about 1,300 lives each year in the UK. MRI scans can detect some aggressive breast cancers even earlier than mammograms.

Unfortunately, MRI scans are expensive, and so the NHS uses them only to screen women at a high risk of developing breast cancer. New evidence suggests that MRI scans can be abbreviated to reduce their cost to the NHS, without affecting their ability to accurately display breast cancers.

FAST MRI is an abbreviated form of MRI which takes less time to acquire (3 vs 20 mins on the scanner) and to interpret (1 vs 10 mins). Unlike mammograms, FAST MRI scans can identify aggressive cancers irrespective of breast density – a trait found more commonly in younger women. Therefore, we are developing FAST MRI for women who are having their first screening by the NHS Breast Screening Programme. We wish to find out if FAST MRI could find aggressive cancers even earlier and smaller for these women because early detection of breast cancer saves lives.

Meet the team:

Dr Lyn Jones

Consultant Radiologist - FAST MRI Programme Lead

Dr Lyn Jones is a Consultant Radiologist specialising in Breast Care. Lyn was struck by the potential for FAST MRI to pick up aggressive breast cancers earlier for women, regardless of their mammographic density, and so she set up the FAST MRI Programme of Research at North Bristol NHS Trust. She became Chief Investigator for local and National Institute for Health and Care Research (NIHR), Research for Patient Benefit (RfPB) grants, designing and testing a training programme for NHS Breast Screening Programme (NHSBSP) mammogram readers to learn to interpret FAST MRI.

Lyn leads the FAST MRI Programme of Research and is currently Chief Investigator for the FAST MRI DYAMOND Study, funded jointly by the Medical Research Council (MRC) and the NIHR, through a grant from their Efficacy and Mechanism Evaluation (EME) funding stream. The study will be the first in the UK to offer a FAST MRI to women who have average mammographic density and are having their first NHS screening mammogram.

Lyn lectures nationally and internationally on breast MRI and has written sessions on breast MRI for the National Breast Imaging Academy.

The BIRCH team

The BIRCH team provides scientific and technical support to a wide range of services within UHBW, external NHS Trusts, NHS screening programmes and other institutions in the region. We have expertise in Magnetic Resonance Imaging (MRI), ultrasound (US) and scientific computing (image processing). Our key services in MRI cover procurement, acceptance and quality assurance (QA) testing, MR safety expert advice, image optimisation and adoption of new techniques. We have also developed in-house phantoms and software for semi-automated MRI QA image analysis.

Personnel involved:

  • Dr Sian Curtis (PhD) is a registered Principal Clinical Scientist specialising in MRI and ultrasound and has worked at UHBW for over 20 years. She is a corresponding member (and previous Chair) of the Institute of Physics and Engineering in Medicine’s Magnetic Resonance Special Interest Group (IPEM MR SIG), a British Medical Ultrasound Society (BMUS) council member and the BMUS representative on the IPEM Ultrasound and Non-Ionising Radiation SIG (IPEM UNIR SIG).
  • Mr Ron Hartley-Davies is a registered Principal Clinical Scientist specialising in MRI and scientific computing and has worked at UHBW for over 20 years. He is the designated MR Safety Expert (MRSE) for UHBW.
  • Mr Jonathon Delve is a registered Clinical Scientist specialising in MRI and scientific computing.
  • Dr Holly Elbert (PhD) is a registered Clinical Scientist specialising in MRI, ultrasound and scientific computing. She did a DPhil in Astrophysics before training in Medical Physics at UHBW from 2016-2019. During her training she did projects in phantom construction and functional MRI analysis, and a placement at the Cardiff University Brain Research Imaging Centre on diffusion MRI analysis.

Public Involvement Members

The FAST MRI programme includes several Public and Patient Involvement representatives. They sit on the Trial Steering Committee giving input into the conduct of the study progress of the trial/project, adherence to the protocol, and the consideration of new information of relevance to the research question. They comment on the rights, safety and well-being of participants and proposals for substantial protocol amendments and provide advice to the sponsor and funder regarding approvals of such amendments.

Their membership is invaluable as they are able to ensure that patients are at the centre of the research conducted as part of the FAST MRI programme; reviewing documentation to make sure that it is written in lay language and that results from the studies are disseminated to the general public.

Public Representatives:

  • Jenny Wookey is the Chair of BUST (North Bristol Trust’s Breast Cancer Unit Support Trust).
  • Jan Rose is a member of the ICPV (Independent Cancer Patient’s Voice) and National Cancer Research Institute Breast Group.
  • Helen Matthews works for the civil service in educational policy. She was diagnosed with high grade ductal carcinoma in situ (DCIS) in November 2021 following a routine screening mammogram, underwent treatment and is now continuing to lead a healthy and active life. She has joined the team to encourage the expansion and effectiveness of routine testing, knowing that it has saved her life.
