						 Introduction: With the improvement in prognosis for patients with breast cancer, reducing long-term toxicity from treatment has become increasingly important. Left breast Radiotherapy (RT usually results in higher dose delivery to the heart and lungs, which are treated as Organs at Risk (OAR. Heart irradiation increases the risk of radiation induced heart disease and major coronary artery disease in long term survivors.
Material and methods: After obtaining informed consent, 50 patients were enrolled in the study between October 2020 and February 2021. Two scans were performed on each patient, one in Free Breathing (FB) and one using Deep Inspiratory Breath Hold technique (DIBH). Contouring of target volume and Organ at Risk (OAR) were performed on both scans. Dose Volume Histograms (DVH) was generated for both scans for plan evaluation. Dos.. Read More»
