New AI model segments MS lesions across time and contrast types

By PulseAugur Editorial · [1 sources] ·

Researchers have developed TimeLesSeg, a novel framework for segmenting multiple sclerosis lesions in medical images. This unified model can process both cross-sectional and longitudinal data without needing contrast agents, overcoming limitations of current methods. TimeLesSeg utilizes a stochastic generative model to simulate lesion evolution and domain randomization for contrast agnosticism, outperforming existing state-of-the-art approaches on multiple datasets.

    TimeLesSeg: Unified Contrast-Agnostic Cross-Sectional and Longitudinal MS Lesion Segmentation via a Stochastic Generative Model

    Multiple sclerosis (MS) expresses substantial clinical and radiological heterogeneity, which poses significant challenges for automatic lesion segmentation. The current deep learning-based SOTA is highly susceptible to changes in both distribution, e.g., changes in scanner; as we…
