摘　　要：磁共振弹性成像(magnetic resonance elastography, MRE)作为一项定量评估组织机械特性的成像技术,以其无创性、准确性、重复性等优势在临床上广泛应用,成为慢性肝病的重要诊断工具,但其在肝脏占位性病变方面的应用还比较局限。目前有不少临床研究证实,MRE在肝脏占位性病变的鉴别中具有一定的诊断效能,且在肝脏恶性肿瘤患者的短期和长期预后上存在良好的预测作用。本文就MRE技术的发展以及其在鉴别诊断肝脏占位性病变和评估肝恶性肿瘤预后方面的研究现状作一综述,并探讨其面临的客观挑战,为研究学者们提供思路,完善MRE在上述研究领域中的相关研究,并推动其临床应用。Magnetic resonance elastography(MRE),as an imaging technique for quantitative assessment of mechanical properties of tissues,is widely applied in clinical practice for its non-invasive,accuracy,and reproducibility,and has become an important diagnostic tool for chronic liver diseases.However,its application in liver focal lesions is relatively limited.A number of clinical studies have confirmed the diagnostic efficacy of MRE in differentiating liver focal lesions,as well as its good predictive role in the short and long-term prognosis of patients with liver malignant tumor.This article reviews the technique development of MRE,as well as its current research status in the differential diagnosis of liver focal lesions and prognostic assessment of liver malignancy,and provides researchers with ideas to refine further research on MRE in the above-mentioned,and to promote its clinical application.
