Cine Short-Axis In, Aorta Contours That Hold Through Systole
Short-axis cine-MRI in. Ascending and descending aorta overlays that survive systolic washout. Teacher ED labels, topology scrub, BiConvLSTM student. Public repo.
MedPixel: Phrase or Loose Box In, Overlay and Sentence Out
Qwen2.5-VL plus SAM2, one reserved token. A phrase or a sloppy ROI hangs a mask and a one-line caption. GitHub exists; weights are still coming.
CoInS-Net: Two Endpoint Slices, One Pass, In-Between Image and Overlay
Shared Swin encoder, physical slice spacing, one forward pass that writes the missing CT or MRI plane and its mask. The preprint lists no code.
3D-CurvSegFlow: One 3D U-Net, Three Euler Steps, Three Vessel Trees
Flow-matching 3D U-Net, three Euler steps, same recipe on portal CT, 7 T TOF-MRA, and coronary CTA. The preprint does not list code.
CoM3eT Pyramid Transformer Lifts Breast MRI Dice From 0.25 to 0.59
Fraunhofer MEVIS freezes Swin-B and adds a pyramid transformer. Breast MRI Dice 25.28% to 58.62% on 3,936 patients. nnU-Net 33.13% on the full set. Public UNICORN_ENCODER is 2D backbone only.
Ten-Case MedSAM3 LoRA Recovers Gallbladder Dice From 0.0003 to 0.68
NTNU and St. Olavs freeze MedSAM3 and train LoRA on 10 TotalSegmentator cases. AMOS22 gallbladder Dice 0.0003 to 0.684. MRSegmentator still leads pancreas. No study code listed.
MedSAM2-Anatomy Recovers Hip MRI Dice from 0.71 to 0.92 Without Retraining
Balgrist and ZHAW compose frozen TotalSegmentator priors with N=3 MedSAM2 tracks. Hip MRI cohort-average median Dice 0.7105 to 0.9242 on 12 FAI cases. Public TS CT still favors the expert CNN. Claimed GitHub 404s.
SAT3D Puts Uncertainty-Guided Tumour Segmentation in 3D Slicer
Nature Communications published SAT3D on 11 August 2026. Mean Dice is 0.672 versus nnU-Net 0.676. A Swin 3D plus voxel-wise critic feeds confidence maps back as dense prompts. Code and a 3D Slicer plugin are public.
SLIP: Interactive 3D Segmentation Needs Latency and Undo
SLIP caches 3D patch features and undoes clicks with 140 MB deltas. Cross-dataset click latency is 0.06 s versus 0.31 s for nnInteractive. MRI uterus still goes to nnInteractive.
CT-DeltaBench: Prior vs Current CT Comparison Is Still Unsolved
CT-ΔBench scores prior-vs-current CT difference reports on 2,638/169 CT-RATE pairs. Zero-shot Change-F1 tops out at 0.0175; DeltaMed full SFT reaches 0.1980.
