Some liver tumors are not visible on ultrasound or non-enhanced CT (NECT) which are main modalities used in image-guided ablations. This is a report of MR-guided implantation of fiducial marker to tag a neuroendocrine tumor metastasis in a patient with renal insufficiency precluding the use of 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-months follow-up.
