摘要:
目的　探讨小肝癌的磁共振多模态功能成像特点，评估其在小肝癌诊断中的价值。方法　选择2016年1月至2018年1月在新乡医学院第一附属医院就诊的39例小肝癌患者为研究对象，总结分析所有患者的磁共振平扫、动态增强检查及弥散成像资料。结果　平扫发现45处病灶，动态增强发现48处病灶，其中速升速降型37处，平台型6处，缓升速降型3处，无明显强化型2处。病灶在弥散加权成像（DWI）上呈高或稍高信号，形态以圆形、类圆形、结节状为主。癌组织和正常肝组织的表观扩散系数（ADC）值随b值的升高呈逐渐降低趋势。同一b值下，癌组织的ADC值均低于正常肝组织（P<0.05）。结论　磁共振多模态功能成像（MRI动态增强联合多b值DWI）可有效提升小肝癌的诊断效能。
Abstract:
Objective　To investigate the magnetic resonance multimodal function imaging characteristics of small hepatocellular carcinoma and evaluate its diagnostic value in small liver cancer.Methods　Thirty-nine patients with small hepatocellular carcinoma were selected in the First Affiliated Hospital of Xinxiang Medical University from January 2016 to January 2018.The magnetic resonance plain scan data，dynamic enhance data and diffusion imaging data of all patients were analyzed.Results　Forty-five lesions were found by plain scan，and 48 lesions（37 lesions were rapid rise and rapid descent type，6 lesions were flatbed type，3 lesions were slow ascent and rapid descent type，2 lesions were not obvious strengthening type） were found by dynamic enhancement.The lesions were hyperintense or slightly hyperintense on the diffusion weighted imaging（DWI） image.The lesions were hyperintense or slightly hyperintense on the DWI.The main shape of lesions was round，irregular ring and nodositas.The apparent diffusion coefficient（ADC） value of cancer tissue and normal liver tissue gradually decreased with the increase of b value.Under the same b value，the ADC values of small hepatocellular carcinoma was significantly lower than that in the normal liver tissue（P<0.05）.Conclusion　Magnetic resonance multimodality functional imaging（magnetic resonance imaging dynamic enhanced combine with multi-b value DWI） can effectively improve the diagnostic efficacy of small hepatocellular carcinoma.
