Abstract: Cervical cancer is a common gynecological malignancy, and radiotherapy plays a crucial role in its treatment. However, conventional radiotherapy for cervical cancer often leads to bone marrow damage, considerably affecting patients’ quality of life and treatment outcomes. In recent years, the application of intensity-modulated radiotherapy (IMRT) and magnetic resonance imaging (MRI) technologies has provided novel solutions to this issue. IMRT optimizes dose distribution, minimizing radiation exposure to surrounding normal bone marrow tissues and thus considerably reducing damage. MRI allows for accurate tumor localization and monitoring, including organs at risk, such as the bone marrow, and providing precise guidance for radiotherapy. This article analyzes the feasibility and potential benefits of MRI-guided pelvic IMRT for bone marrow protection in cervical cancer, aiming to offer a basis for precise and effective bone marrow protection strategies in cervical cancer radiotherapy.
