Detectability and structural stability of a liquid fiducial marker in fresh ex vivo pancreas tumour resection specimens on CT and 3T MRI

ConclusionsThe liquid fiducial marker injected inex vivo pancreatic resection specimen was visible as hyperintensity on kV X ‑ray and CT and as hypointensity on MRI. The marker’s size was stable in formaldehyde. A marker volume of ≥50 µL is recommended in clinically used MRI sequences.In vivo injection is expected to improve the markers sphericity due to persisting metabolism and thereby enhance detectability on MRI.
