磁共振扩散加权成像在肝癌介入疗效评估中的研究进展

The application of diffusion-weighted magnetic resonance imaging in evaluating the therapeutic efficacy of hepatoceilular carcinoma intervention

磁共振扩散加权成像（MRDWI）作为一种分子水平的功能成像技术，与其他影像学检查（DSA，CT，B超）相比具有无创、无辐射、客观等诸多优势，已广泛应用于临床。DWI在肝癌介入疗效评估中有广阔的应用前景。本文对DWI在监测肝癌介入疗效中的应用价值、有关技术要求及应用前景等方面进行综述。

Magnetic resonance diffusion-weighted imaging （MR-DWI） is a functional technology at the molecular level. Compared to other imaging exams （such as DSA, CT, US）, DWI is non-invasive, has no radiation, and objective. Thus, it is widely accepted in clinical settings. As a means to assess the therapeutic efficacy of intervention, DWI has a promising prospect. In this article, we review the application of MR-DWI in evaluating the therapeutic efficacy of hepatocellular carcinoma intervention.
