New PET registration method enhances cancer volume and glycolysis tracking

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for registering longitudinal whole-body PSMA PET/CT scans, adapting the LapIRN architecture for the Learn2Reg 2026 PSMAReg challenge. Their approach incorporates affine pre-registration, multi-modal deformable registration, and test-time instance optimization. Key innovations include PET biomarker preservation losses for metabolic tumor volume (MTV) and total lesion glycolysis (TLG), along with Jacobian-based constraints and structure-specific rigidity regularization, achieving competitive results in segmentation accuracy and biomarker error.

    PET Quantification-Preserving Registration for Longitudinal Whole-Body PSMA PET/CT

    arXiv:2610.21451v1 Announce Type: new Abstract: We adapt the diffeomorphic coarse-to-fine LapIRN architecture for longitudinal whole-body PSMA PET/CT registration in the Learn2Reg 2026 PSMAReg challenge. The method combines affine pre-registration, multi-modal deformable registra…
