Think MRI room turnaround takes too long? Not necessarily. At UW Health’s Eastpark Medical Center: ⏱️Room turnaround time: dropped from 12min→ 2 min 📈+2,600 patients/year ow.ly/sjPc50YYZLP #radiology #CHVI #MRI @DaniaDaye @UWiscRadiology @UWHealth

@RSNA @RITEditor @RadiologyEditor @VChernyakMD @SuhnyAbbara 2/10 🔬 Maiter et al. tested 7 CE-marked commercial #AI devices on the SAME 5,235 consecutive primary care CXRs from Sheffield, UK. 📊 Lung cancer prevalence: 1.4% — matching real-world rates 🏥 NHS-funded, zero manufacturer involvement

One #AI missed 8 in 10 lung CA. Another generated 2,039 false positives. Both are CE-marked (approved in EU) & deployed. How? Recent @RSNA study investigated what "approved" means for #AI in #LungCancer detection on CXR. 👇 @RITEditor @RadiologyEditor @VChernyakMD @SuhnyAbbara

🧵 Can routine #MRI show who's at risk for #Cardiometabolic disease before diagnosis? New @Radiology_RSNA study (>11k participants) shows that #muscle composition is strongly linked to hidden risk. pubs.rsna.org/doi/10.1148/ra… pubs.rsna.org/doi/10.1148/ra… @RITEditor @RadiologyEditor

🧲Liver stiffness in severe obesity: 2D or 3D MRE? Prospective study (n=103): 3D MRE = better precision 📉✅ but more failures than 2D ⚠️ A key trade-off for pre/post bariatric surgery. pubs.rsna.org/doi/10.1148/ra…

13/13 🌟 2D MRE is still acceptable and practical. But when precision matters (clinical trials, longitudinal monitoring) 3D MRE is the better choice💡 Kudos to @LuMueRad, @ClaudeSirlin, @ScottReederMD & the full team 👏 🔗 pubs.rsna.org/doi/10.1148/ra…

12/13📝Summary: ✅3D MRE outperforms 2D MRE in precision across three reproducibility settings ✅First precision data in severe obesity ✅Storage modulus shows promise ⚠️Higher failure rate at 3T ⚠️Predominantly female cohort ⚠️Low fibrosis prevalence ⚠️Single MRI vendor

1/13 🎯 MASLD is the most common chronic liver disease. FDA just approved drugs for fibrotic MASH. To monitor treatment response, we need precise liver stiffness measurements. Do we have the right tool for patients with obesity?

@radiology_rsna study shows how redefining washout criteria on gadoxetate-enhanced MRI can improve LI-RADS performance for HCC detection. 🧬📊 Let’s dive into this #RIAM (Radiology in a Minute)👇🏻 @RadiologyEditor @RITEditor @VChernyakMD #RadInTraining 🔗pubs.rsna.org/doi/10.1148/ra…

Excited to share this new book on Cardiac CT! Forever grateful to Dr. Braunwald who asked me to write this and for his guidance and mentorship along the way. While we are mourning his recent passing, I will treasure all the conversations I had with him on #CCT and #Prevention
