Some liver tumors are not visible on ultrasound or non-enhanced computed tomography (NECT) which are the main modalities used in image-guided ablations. This is a report of magnetic resonance-guided implantation of a fiducial marker to tag a neuroendocrine tumor metastasis in a patient with renal insufficiency precluding the use of a contrast-enhanced CT during ablation. The marker was well visible on NECT which allowed for precise needle placement and complete ablation which was confirmed in 12-month follow-up.
