This dataset contains synthetic data created by a generative AI model.

This dataset is a collection of synthetic images generated by 5 generative models (Progressive GAN, StyleGAN1, StyleGAN2, StyleGAN3, diffusion model) trained on the BraTS 2020 and 2021 datasets [1,2,3,4,5] (which share MR volumes from brain tumor patients and the corresponding tumor annotations). The trained generative models are also shared in this dataset. See our recent work [6] for more information, and a comparison of training segmentation networks with real and synthetic images.

Keywords: Radiology, Annotated, Brain, MRI, Tumor, Synthetic, Generative, GAN, Diffusion model.
