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.

Hi!
I work at INSTITUTION in COUNTRY, emailing from my institutional account.
I would like to access the dataset doi:10.23698/aida/synthetic/brgandi, for use in ethical and legal medical diagnostics research. Could you please send me a data sharing agreement template?
Our planned use of the data can be summarized as:
