Background/Purpose We describe the feasibility and accuracy of magnetic resonance (MR)‐guided cryotherapy for malignant liver tumor, using a horizontal‐magnetic open system. Methods Using an MR‐compatible cryotherapy system and horizontal‐magnetic open‐configuration MR scanner, we performed percutaneous cryotherapy for four malignant liver tumors. Results All procedures were carried out safely and accurately without any serious complication. Residual tumor was observed in one patient with metastatic liver tumor located directly under the diaphragm. Conclusions MR‐guided cryotherapy appears to be ideal and desirable as a minimally invasive therapy for liver tumor.
