AI synthesizes controllable glioblastoma MRI scans using latent diffusion models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel two-stage latent diffusion model (LDM) framework designed to synthesize controllable 2D glioblastoma MRI scans. The first stage generates tumor segmentation maps based on specified location, extent, and composition. The second stage uses a modality-conditioned LDM with ControlNet to produce T1, T1Gd, T2, and FLAIR images that align with the generated segmentations. This approach demonstrated improved image quality and reduced Fréchet inception distance (FID) compared to previous methods, with expert readers rating the synthetic images comparably to real ones. AI

    Spatially and Compositionally Controlled Multimodal Glioblastoma MRI Synthesis with Latent Diffusion

    arXiv:2611.06540v1 Announce Type: new Abstract: Glioblastoma exhibits substantial heterogeneity in tumour morphology and composition across MRI modalities, often making available clinical datasets highly unbalanced in terms of patient pathologies. We propose a two-stage latent di…
