BreastDCEDL_ISPY Dataset

BreastDCEDL_ISPY is a curated dataset of pre-treatment 3D dynamic contrast-enhanced MRI (DCE-MRI) scans from 1,154 breast cancer patients, combining data from two major clinical trials:

• I-SPY1: 172 patients
• I-SPY2: 982 patients

Each patient includes 3 selected DCE-MRI scans:

• Pre-contrast
• Early post-contrast
• Late post-contrast

This minimal version was derived from the full TCIA archives and optimized for deep learning applications in breast cancer imaging and outcome prediction.
