新型扩散模型增强 MS 病灶 MRI 扫描合成

研究人员开发了 Lesion-DDPM,一个新颖的 3D 条件扩散框架,旨在为多发性硬化症 (MS) 研究合成医学图像。该方法特别增强了准确表示 MS 数据集中常见的小而稀疏的病灶的图像生成能力。通过结合多级解剖掩模注入和病灶加权重建损失,Lesion-DDPM 旨在提高神经影像机器学习模型的鲁棒性。实验表明,在 Lesion-DDPM 生成的扫描上训练的模型,与在现有合成数据集或仅真实扫描上训练的模型相比,在下游病灶分割任务上取得了更好的性能。 AI

影响 提高了 MS 研究的合成数据质量,可能加速诊断 AI 模型的开发。

    Lesion-DDPM:增强病灶的3D扩散用于MS MRI合成

    arXiv:2606.15457v1 Announce Type: cross Abstract: 3D FLAIR MRI is widely recommended as one of the standard MRI sequences for brain imaging in multiple sclerosis (MS), but publicly available MS datasets remain relatively small and vary across scanners, acquisition protocols, and …
