Partial Intraop Ultrasound In, a Complete Lumbar Spine Mesh Out
Partial intraoperative lumbar US bone surface in. Watertight whole-spine mesh out in about 8 seconds. Zero-shot octree diffusion (ZODIAC), TUM CAMP. arXiv:2608.24422.
Axial CT Slice In, Organ Boxes and an Auditable Left/Right Call Out
One axial CT slice plus a binary spatial question. YOLO boxes, centroid geometry, then a 1/0 with an audit trail. YOLO weights ship; VLM checkpoints do not.
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.
