目的：探讨磁共振在小肝癌诊断中的价值，总结小肝癌磁共振的影像学表现。方法回顾性分析经临床及病理证实的32例患者磁共振检查影像学资料，分析其平扫及动态增强表现。结果32例患者共发现34个病灶，17个病灶见假包膜形成。 T1加权像（T1WI）发现病灶23个，其中18个病灶呈略低信号，5个病灶呈略高信号，13个病灶见假包膜形成；T2加权像（ T2WI）发现病灶30个，均呈稍高信号；动态增强扫描共发现病灶34个，有32个病灶动脉期强化，其中27个动脉期强化最明显，呈快进快出表现，5个病灶门脉期强化最明显，病理检查为高分化小肝癌。结论磁共振多序列成像在小肝癌的检出及早期诊断中起重要作用，并在一定程度上反映病灶的分化程度。

Objective To investigate the value of MRI in the diagnosis of small hepatocellular carcinoma, summarize magnetic resonance imaging of small hepatocellular carcinoma .Methods A retrospective analysis was conducted on MRI imaging dataof 32 cases of patients who were confirmed as hepatocellular carcinoma by clinical and pathological datas , analyzedthe plain and dynamic enhanced performance .Results A total of 34 lesions were found in 32 patients, fake capsule formation was found in 17 lesions.T1-weighted images ( T1WI) found 23 lesions, of which 18 lesions were slightly lower signal , five lesions were slightly hyperintense , fake capsule formation was found in 13 lesions.T2-weighted images ( T2WI) found lesions 30, showed slightly higher signal.Dynamic enhanced MRI found34lesions, there were 32 lesions in the arterial phase enhancement , of which 27 arterial strengthening were obvious , performed fast access and exit , five lesions were proved to be portal strengthening , and firmed as smallhepatocellular carcinoma through pathological examination .Conclusions Multiple sequences magnetic resonance imaging plays an important role in the early detection and diagnosis of small hepatocellular carcinoma , and to some extent reflects the degree of differentiation of lesions .
