The utilization of breast MRI is increasing in the diagnostic evaluation of suspicious breast findings. As more imaging
centers implement dedicated breast MR, the need for managing data on a large scale, nationally and even some times
internationally, has become more apparent. Our design proposal is to utilize the data grid for managing the storage of the
medical images and an ePR that provides the interface to manage the health data of Breast Cancer Patients. In this
paper, we present the data grid for DICOM images and DICOM-SR data and the image-intensive web-based ePR system technologies utilizing the simulation of a three-site dedicated breast MR outpatient centers as the clinical application. The implementation of the two technologies the ePR system together with the Breast Imaging Data Grid (BIDG) can provide a global solution that is portable for the Breast Cancer patient including aggregation of Mammo, US, MR, CAD, BI-RADS, and clinical related reports data to form a powerful platform for data mining and outcomes research.
