 # BreastDCEDL_ISPY Dataset
 
-This dataset is part of the BreastDCEDL collection and includes only the **I-SPY1** cohort.  
-It contains pre-treatment 3D dynamic contrast-enhanced MRI (DCE-MRI) scans from **172 breast cancer patients**, curated for deep learning applications.
+**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.
