A novel liquid fiducial marker in esophageal cancer image-guided radiotherapy: technical feasibility and visibility on imaging

ConclusionInjection of a liquid fiducial marker for esophageal cancer radiotherapy is technically feasible with no adverse events observed. Volumes of>0.05 ml have an appropriate visibility on CT, CBCT, and MRI, with an excellent positional stability. Liquid fiducial markers are therefore promising for use in image-guided radiotherapy.
