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.
背景/目的：我们描述了使用水平开放式磁共振（MR）系统对恶性肝肿瘤进行MR引导下冷冻治疗的可行性和准确性。
方法
使用MR兼容的冷冻治疗系统和水平开放式配置的MR扫描仪，我们对4例恶性肝肿瘤患者进行了经皮冷冻治疗。
结果
所有手术均安全、准确地进行，无任何严重并发症。1例位于膈肌正下方的转移性肝肿瘤患者观察到残留肿瘤。
结论
MR引导下的冷冻治疗似乎是一种理想的、令人满意的肝肿瘤微创治疗方法。
