Practical considerations of gadoxetate disodium contrast in MRI-guided liver SBRT for primary and secondary liver tumors: optimizing image quality and patient throughput.
PURPOSE/OBJECTIVES Optimal implementation of gadoxetate disodium injection (GDI) in liver-directed MR-guided online adaptive radiotherapy (MRgART) remains poorly characterized. Herein, we evaluated the impact of GDI on physician-reported imaging metrics and quantitative contouring variability during liver MRgART planni...
