Evaluation of a fast-volumetric four-dimensional magnetic resonance imaging technique for abdominal radiotherapy tumor motion management

Our preliminary results demonstrated that the commercially available TWIST-VIBE 4D-MRI sequence provides precise volumetric tumor motion tracking suitable for clinical abdominal radiotherapy. Its rapid acquisition and reliable image quality facilitate seamless workflow integration, potentially enhancing treatment precision and improving patient outcomes. The technique offers a practical alternative to existing imaging modalities by combining speed, spatial coverage, and soft tissue contrast without additional hardware requirements. Further efforts will target artifact minimization, optimization of spatial and temporal resolutions, improved clinical decision-making impact, and broader multi-center validation to ensure robust clinical implementation and generalizability across diverse patient populations.

Abstract

Our preliminary results demonstrated that the commercially available TWIST-VIBE 4D-MRI sequence provides precise volumetric tumor motion tracking suitable for clinical abdominal radiotherapy. Its rapid acquisition and reliable image quality facilitate seamless workflow integration, potentially enhancing treatment precision and improving patient outcomes. The technique offers a practical alternative to existing imaging modalities by combining speed, spatial coverage, and soft tissue contrast without additional hardware requirements. Further efforts will target artifact minimization, optimization of spatial and temporal resolutions, improved clinical decision-making impact, and broader multi-center validation to ensure robust clinical implementation and generalizability across diverse patient populations.
