摘　　要：目的探讨磁共振弥散加权成像(DWI)联合肝脏容积超快速三维成像(LAVA)技术对肝癌分期的临床价值。方法选取2008年9月至2011年12月在牡丹江医学院第二附属医院治疗的肝癌患者177例作为研究对象,将177例患者的磁共振检查资料进行回顾性分析,比较DWI序列、LAVA技术、DWI+LAVA技术三种序列的检查方法对直径<3 cm的小肝癌检出率、血管瘤栓的检出率及转移淋巴结的检出率。结果 DWI+LAVA技术序列小肝细胞癌的检出率为73.73%、血管瘤栓的检出率为74.19%、转移淋巴结的检出率为77.22%,均著显高于LAVA技术、DWI两种序列(均P<0.05)。结论 DWI联合LAVA技术对肝癌分期有着重要的辅助指导意义,可以在临床推广此种检查方法。Objective To discuss the clinical value of magnetic resonance diffusion-weighted imaging （DWI） combined with LAVA technology for liver cancer staging. Methods A retrospective analysis of nuclear magnetic resonance examination information of 177 patients with liver cancer in the Second Affiliated Hospital of Mudanjiang Medical University from Sep. 2008 to Dec. 2011 was done. They were divided into DWI （ group A）, LAVA technology （ group B ） and DWI ＋ LAVA technology （ group C ） , and a comparison about detection rates of small liver cancer with diameter 〈 3cm, blood vessel tumor thrombus and metastatic lymph nodes was made. Results In group C, the detection rate of small liver cancer was 73.73 %, the detec- tion rate of blood vessel tumor thrombus was 74. 19%, the detection rate of metastatic lymph nodes was 77.22%, all significantly higher than group A and B （ all P 〈 0.05 ）. Conclusion DWI combined with LAVA technology has an important guiding significance for liver cancer staging, so it＇s suggested to be widely used in clinical.
