10/10 Takeaway 📌
• 🟠AC was the best of the 3 markers for grading, with AUC ~0.9 from any fat to severe fat
• 🔵NLV and 🟢hepatorenal ratio detected fat but graded it less well
• Combining them improved reclassification, not AUC; validation needed

1/10 Can #ultrasound grade #liver fat, not just detect it? 🆕 in @Radiology_RSNA: 3 US markers vs biopsy in #MASLD. Spoiler: the attenuation coefficient held up at every grade. #RadInTraining #Tweetorial @RadiologyEditor @VChernyakMD @RITEditor @SuhnyAbbara

9/10 Caveats ⚠️
• Secondary analysis; 102 participants, only 10 with S0
• Single vendor (Canon); AC values and cutoffs may not transfer
• Models built and tested on the same data; authors weight AUC over NRI
• No inter- or intraobserver variability data

📊10/10
How will you report luminal narrowing + 2.5–3 cm prestenotic dilatation in routine CD CTE?
A) Stricture + tighter FU
B) Stricture + flag for antifibrotic trial
C) "Probable stricture"
D) Wait for multicenter data

💡9/10 — Take-home
In routine CD CTE without acute obstruction, the ≥2.5 cm threshold identifies an additional 13.4% of patients and adds prognostic information beyond clinical covariates. The 2.5–3 cm subgroup may warrant closer monitoring and future trial attention.
