• To highlight patient selection, equipment, and procedural planning.

Main Methods:

• Utilizes intra-procedural planning imaging for visualization without contrast agents.
• Employs real-time, multiplanar MRI for applicator and tumor observation.
• Monitors ablation zone appearance for therapy assessment.

Main Results:

• Achieves high primary efficacy rates and positive outcomes for smaller neoplasms.
• Demonstrates high technical success, survival, and recurrence rates.
• MR-guided percutaneous biopsy offers improved lesion detection.

Conclusions:

• MR-guided liver ablation shows positive outcomes, especially for smaller tumors.
• Ongoing advancements in hardware, software, and devices can expand its clinical use.
• High costs and specialized expertise currently limit routine clinical application.
