MRIComp4Flow: Compression of 3D Brain MRI for Training Multi-Modal Generative Models

Lisa K. Fischer, Mykhailo Riabets, Daniel Rueckert +3

Large-scale multi-modal MRI datasets impose substantial storage and I/O costs, limiting the training of 3D generative models on commodity infrastructure. While lossy compression is…

TumorFlow: Physics-Guided Longitudinal MRI Synthesis of Glioblastoma Growth

Valentin Biller, Niklas Bubeck, Lucas Zimmer +6

Glioblastoma exhibits diverse, infiltrative, and patient-specific growth patterns that are only partially visible on routine MRI, making it difficult to reliably assess true tumor…
