Use of Magnetic Resonance Imaging to Guide Preoperative Accelerated Partial Breast Irradiation in the Prone Position and Behandeling Response in Clinical Stage 1 Hormone Sensitive Borstkanker: A Phase 1/2 Studie

The challenges of postoperative accelerated partial breast irradiation (APBI) include targeting inaccuracies and inability to measure tumor response. We hypothesized that the tumor could be targeted with preoperative APBI (pAPBI) using magnetic resonance imaging (MRI) in prone position with our established prone breast technique. This feasibility study aimed to assess the accuracy and tumor response of pAPBI using our MRI/computed tomography (CT)-guided prone technology.
