Percutaneous MRI guided abdominal interventional procedures are routinely performed include aspiration, biopsy, targeted drug delivery and thermal ablation. These procedures benefit from excellent soft tissue contrast, multi-planar imaging capabilities, near real-time fluoroscopic sequences and absence of ionizing radiation with MRI. For thermal ablation, the excellent soft tissue contrast as well as the ability to measure temperature in-vivo non-invasively using MR thermometry are beneficial for monitoring and control of thermal ablation. Direct intraprocedural temperature measurements, although technically challenging, facilitate immediate feedback on complete tumor destruction thus guaranteeing complete (A0-) ablation while, at the same time, healthy surrounding tissue can be protected. Unfortunately, MRI guided procedures are still being performed primarily at academic hospitals. The complexity of the current interventional MRI workflow is one of the primary barriers to more widespread adoption. The goal of this presentation is, to discuss potential applications for MRI guided procedures in the abdomen and to provide different solutions to make such procedures a clinical reality.
