New CIRSeg framework improves liver segmentation in MRI scans

By PulseAugur Editorial · [1 sources] ·

Researchers have developed CIRSeg, a novel framework for segmenting livers in contrast-enhanced MRI scans. This method addresses challenges like limited annotated data and variations in MRI intensities across different scanners. CIRSeg employs a coarse-to-fine architecture that first localizes the liver and then refines its boundaries, incorporating techniques like 3D CutMix and histogram matching for intensity robustness. At inference, it uses source-free test-time adaptation to further enhance performance on unseen data, achieving high Dice scores and low HD95 values on the CARE 2026 test set. AI

IMPACT Enhances accuracy and robustness in medical image analysis, potentially improving diagnostic and treatment planning capabilities.

    CIRSeg: Coarse-to-Fine Intensity-Robust Liver Segmentation with Source-Free Continual Test-Time Adaptation

    arXiv:2610.09784v1 Announce Type: new Abstract: Reliable liver segmentation in contrast-enhanced MRI is essential for quantitative hepatic assessment, treatment planning, and longitudinal disease monitoring. However, limited annotated data and scanner- or vendor-dependent intensi…
