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.
