磁共振引导下肝肿瘤热消融治疗现状与进展

MR-guided thermal ablation of liver tumors: current status and research progress

影像引导热消融治疗肝恶性肿瘤得到广泛认可并成为肝肿瘤微创治疗的首选方案。MR软组织分辨率高、无辐射损伤、任意角度成像和无创热成像等优势,可提高肿瘤定位精度并实时显示消融过程、监测消融范围,为精准热消融提供助力。近年来,随着MR引导下肝肿瘤热消融逐渐成熟,热消融治疗近膈部、血管等特殊部位肝肿瘤成为可能。本文旨在对MR引导下肝肿瘤热消融的背景、治疗过程、研究现状及进展进行综述。

Imaging-guided thermal ablation for the treatment of liver malignant tumors has been widely accepted, and it has been regarded as the first choice for minimally-invasive treatment of liver tumors. Magnetic Resonance(MR) has many advantages such as high soft tissue resolution, no radiation damage, arbitrary angle imaging displaying, non-invasive thermal imaging, etc. It can improve the accuracy of tumor localization,display the real-time ablation process and monitor the ablation range, thus, providing assistance for accurate thermal ablation. In recent years, with the technical development and maturation of MR-guided thermal ablation for liver tumors, it becomes possible that the liver tumors located close to the diaphragm or blood vessels can also be treated by thermal ablation therapy. This paper aims to make a comprehensive review about MR-guided thermal ablation of liver tumors, focusing on the academic background, treatment process,research status and research progress.(J Intervent Radiol, 2021, 30: 1068-1071)
