title: Target volume delineation in external beam partial breast irradiation: less inter-observer variation with preoperative- compared to postoperative delineation.
abstract: The challenge of adequate target volume definition in external beam partial breast irradiation (PBI) could be overcome with preoperative irradiation, due to less inter-observer variation. We compared the target volume delineation for external beam PBI on preoperative versus postoperative CT scans of twenty-four breast cancer patients.
