MRI shows a 4–5% muscle/lean mass decline over ~2.5 years — missed by DXA. Bottom line: DXA is practical at scale, but MRI gives a more precise picture of lean mass change, especially in ageing and longitudinal studies.

Using deep learning on 44k @uk_biobank abdominal MRIs, we mapped heart and vascular structures, linked these traits to CVD risk, and uncovered 15 new genetic associations. Abdominal MRI is a powerful, untapped tool for understanding cardiovascular health rdcu.be/e5f3C

I was ridiculously excited to meet @AuntMinnie today! You never know what’s going to happen next at @RSN. There is just so much to explore. A fantastic first day #RSNA25

We’re proud to share the publication of a new paper in the Journal of Abdominal Radiology on automated MRI quantification of body fat and skeletal muscle. Study highlights: ✅ For clinicians: A rapid, single-slice assessment of body fat and muscle, strongly correlated with gold-standard volumetric measures, to support routine monitoring, triage, and decision-making. 💊 For pharma: Trial-ready volumetric MRI biomarkers for body composition, validated against expert manual segmentations and interchangeable across methods and vendors, enabling objective, scalable endpoints in obesity, cardiometabolic and musculoskeletal trials 👏 Congratulations to Magdalena Nowak, Luis Núñez, Charles E. Hill, Tim Pagliaro, John McGonigle, Marili Niglas, Camilo Bell-Bradford, Matthew Robson, Helena Thomaides Brears, E. Louise Thomas, and Jimmy D. Bell on this important contribution. 🔗 link.springer.com/article/10… 👉 BBC bbc.co.uk/news/articles/c8d6… #Perspectum #BodyComposition #MedicalImaging #ClinicalResearch #Pharma #ClinicalTrials #UKBiobank #Collaboration

Found my old Queen Mary and Westfield scarf this week while having to empty our attic. Was so excited but washed and shrunk it 😱 Are these ones still available @QMUL or have they changed now your are QMUL. When I joined you were QMC, and became QMW while I was a student.
