The BraTS 2023 Inpainting Challenge has begun!

Ever wondered what the brain of a tumor patient looked like before they developed the disease? This question keeps doctors awake at night. Help them by joining the #BraTS2023 Inpainting Challenge!

A myriad of algorithms for automatic analysis of brain MR images is available to support clinicians in their decision-making and clinical care. For brain tumor patients, the image acquisition time series typically starts with a scan that is already pathological. This poses problems, as many algorithms are designed to analyze healthy brains and provide no guarantees for images featuring lesions. Examples include but are not limited to algorithms for brain anatomy parcellation, tissue segmentation, and brain extraction. To solve this dilemma, we introduce the BraTS 2023 inpainting challenge.

Your mission will be to develop innovative inpainting techniques to synthesize healthy brain scans from lesioned ones. Dive into the complexities of brain anatomy, tissue segmentation & more. Let’s tackle this real-world challenge together! Find out more details on our website, and don’t forget to follow us on Twitter.

In this challenge you will have the possibility to:

  • Experiment with algorithmic solutions for synthesizing 3D healthy brain tissue
  • Work on an exciting dataset of more than 1000 brain MRI scans 
  • Contribute to the challenge manuscript 
  • Be part of the solution at MICCAI 2023 in Vancouver, Canada
