MRI Motion Imaging for Precision Radiotherapy

Abstract

MRI has unique advantages over CT for motion management in radiation therapy, such as its flexible imaging plane, versatile imaging techniques including fast and ultra-fast MR sequences. There has been a great deal of developments recently in the area of MRI motion imaging, motion compression, and MRI-guided treatment for moving tumors. This presentation will: 1) outline the recent developments in MRI-based motion management, with examples to demonstrate the pro and cons of different 4D-MRI techniques, MRI motion artifacts reduction, and clinical applications of MRI-based motion management; 2) discuss key challenges in the development and clinical implementation of MRI-based motion management techniques, and 3) provide overviews of current efforts to address such challenges in the research and clinical communities.
