Abstract
CLINICAL/METHODICAL ISSUE: Optimizing radiotherapy demands precise delineation of the target structure, not only before but also during the course of radiotherapy.
STANDARD RADIOLOGICAL METHODS: For many years, planning of external radiation treatment planning has been based on computer tomography data.
METHODOLOGICAL INNOVATIONS: With the advent of image-guided radiotherapy (IGRT), magnetic resonance imaging (MRI) and functional hybrid imaging are increasingly being integrated into radiation treatment planning. The development of the MR-linac can be seen as an innovation.
PERFORMANCE: The integration of MRI and hybrid imaging (positron emission tomography [PET]/CT, PET/MRI) in the treatment planning process enables more precise treatment planning due to the better morphological and functional information. The integration of MRI data on the MR-linac in daily position control enables adaptation of the irradiation plan to the current conditions.
ACHIEVEMENTS: Technical innovation such as the MR-linac as well as increasing use of hybrid imaging contribute to the objective of further individualization within (radio)oncology.
PRACTICAL RECOMMENDATIONS: Using the example of prostate cancer, the application of prostate-specifi...
