The MAMA-MIA challenge aims to advance the field with two complementary tasks: (1) Primary Tumour Segmentation<\/strong> and (2) Prediction of Pathologic Complete Response to Neoadjuvant Chemotherapy <\/strong><\/strong>based on pretreatment dynamic contrast-enhanced MRI (DCE-MRI), leveraging imaging and clinical data. With 1,506 training cases<\/strong> from more than 20 clinical centres in the United States and a private set of over 570 test cases <\/strong>from three European centres (Spain, Poland and Lithuania), this challenge comprises the largest breast MRI dataset to date with 3D primary tumour segmentations approved by more than 16 experts from all over the world.<\/p>\n\n\n\n

The challenge will incorporate metrics like Equal Opportunity Difference and Performance Disparities to measure biases across demographic subgroups, making it the first challenge to emphasize ethical AI deployment in breast cancer imaging. <\/strong><\/p>\n\n\n\n

Top 5 teams on each task and the winners of the Best Paper Award will be invited to contribute to a challenge summary publication.<\/p>\n\n\n\n

The participation policies are desceribed in detail in the MICCAI Challenge Proposal.<\/p>\n<\/div>\n\n\n\n
