Regular imaging assessments of heart function are needed to see how the heart is \u2018doing\u2019 and how well it is responding to treatment with heart drugs. Echocardiography (echo) has been the standard type of imaging used for these assessments in the UK. It is widely available but has limitations. Cardiac MRI (CMR), although less readily available and more expensive, is better able to detect tissue changes in the heart before there is any reduction of heart pump function and retains accuracy in all measures even as DMD progresses. An expert panel of cardiologists, muscle specialists and patient representatives was set up to review evidence and provide expert guidance on how to use both echo and CMR best to the benefit of patients with DMD, Becker muscular dystrophy (BMD) and females affected by DMD-gene abnormalities (\u2018female gene carriers\u2019).<\/jats:p>\n                  <jats:p>The working group concluded that echo should remain the predominant method used in heart checks for patients with DMD in the UK. However, wider use of CMR, performed at times individualised to key decision points after about the age of 10\u2009years, would allow earlier detection of those heart changes prompting the introduction and changes in heart therapies. Similarly, greater use of CMR could contribute to improving cardiac management of males with BMD and females with DMD-gene variations.<\/jats:p>\n                  <jats:p>_______________________<\/jats:p>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To provide guidance on the use of cardiac MRI (CMR) in the UK in paediatric and adult patients with Duchenne muscular dystrophy (DMD) or Becker muscular dystrophy (BMD) as well as recommendations for screening and monitoring females with dystrophin-gene variations. Specifically, to examine the \u2018added value\u2019 of CMR over echocardiography at selected time points in the assessment of individuals with or at risk of developing cardiac dystrophinopathy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Initiated by an expert working group of UK-based and US-based imaging cardiologists, neuromuscular clinicians and DMD-patient representatives, draft guidelines were created based on published evidence, current practice and expert opinion.

However, when tolerated, wider use of CMR at key stages in patients with DMD, older than age 10\u2009years, and for males with BMD and females with DMD-gene variations would allow earlier detection of those with cardiac involvement and inform the earlier initiation of regimes of cardiac medications. In this way, greater use of CMR could contribute to improving cardiac health in each of these patient groups.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/openhrt-2026-004037","type":"journal-article","created":{"date-parts":[[2026,5,20]],"date-time":"2026-05-20T14:15:33Z","timestamp":1779286533000},"page":"e004037","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Cardiac MRI in cardiac dystrophinopathy: recommendations on imaging"],"prefix":"10.1136","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-1780-1575","authenticated-orcid":false,"given":"Adam","family":"McDiarmid","sequence":"first","affiliation":[{"name":"Department of Cardiology, Freeman Hospital, Newcastle upon Tyne, UK"},{"name":"Biosciences, Newcastle University, Newcastle upon Tyne, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Augustine","sequence":"additional","affiliation":[{"name":"Royal United Hospital Bath NHS Trust, Bath, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"Coats","sequence":"additional","affiliation":[{"name":"University of Glasgow, Glasgow, Scotland, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saul G","family":"Myerson","sequence":"additional","affiliation":[{"name":"Cardiovascular Medicine, University of Oxford Radcliffe Department of Medicine, Oxford, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Hughes","sequence":"additional","affiliation":[{"name":"Norfolk and Norwich University Hospital NHS Trust, Norwich, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chet","family":"Villa","sequence":"additional","affiliation":[{"name":"Cardiology, Cincinnati Children\u2019s Hospital Medical Center, Cincinnati, Ohio, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9194-5330","authenticated-orcid":false,"given":"Jonathan","family":"Soslow","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Vanderbilt University Medical Center, Nashville, Tennessee, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kadhim","family":"Kadhim","sequence":"additional","affiliation":[{"name":"Freeman Hospital Cardiothoracic Centre, Newcastle upon Tyne, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam","family":"Kerr","sequence":"additional","affiliation":[{"name":"John Walton Muscular Dystrophy Research Centre, University of Newcastle upon Tyne, Newcastle upon Tyne, Tyne And Wear, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa","family":"Kuhwald","sequence":"additional","affiliation":[{"name":"Duchenne UK, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7065-3942","authenticated-orcid":false,"given":"Daniel M","family":"Sado","sequence":"additional","affiliation":[{"name":"Cardiology, King\u2019s College Hospital NHS Foundation Trust, London, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7162-7079","authenticated-orcid":false,"given":"Peter","family":"Swoboda","sequence":"additional","affiliation":[{"name":"LICAMM, University of Leeds, Leeds, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6674-6970","authenticated-orcid":false,"given":"Cathy","family":"Turner","sequence":"additional","affiliation":[{"name":"John Walton Muscular Dystrophy Research Centre, University of Newcastle upon Tyne, Newcastle upon Tyne, Tyne And Wear, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michela","family":"Guglieri","sequence":"additional","affiliation":[{"name":"John Walton Muscular Dystrophy Research Centre, University of Newcastle upon Tyne, Newcastle upon Tyne, Tyne And Wear, UK"},{"name":"Newcastle Upon Tyne Hospitals NHS Foundation Trust, Newcastle upon Tyne, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7857-9073","authenticated-orcid":false,"given":"John","family":"Bourke","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Freeman Hospital, Newcastle upon Tyne, UK"},{"name":"John Walton Muscular Dystrophy Research Centre, University of Newcastle upon Tyne, Newcastle upon Tyne, Tyne And Wear, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,5,20]]},"reference":[{"key":"2026052007152657000_13.1.e004037.1","doi-asserted-by":"crossref","unstructured":"Crisafulli S , Sultana J , Fontana A , et al .
