多层螺旋CT对小肝癌的诊断分析

目的研究小肝癌（SHCC）在l6层螺旋CT（SCT）多期（动脉期、门脉期和延迟期）增强扫描的表现特征。方法对本院经病理证实的56例小肝癌患者的影像学资料进行回顾性分析。结果患者动脉期的病灶数要明显高于门静脉期和延迟期,差异有统计学意义（P〈0.01）,动脉期的敏感性高于门脉期和延迟期。小肝癌总的病灶栓出率为94.6%（53/56）,动脉期、门静脉期和延迟期的病灶检出率分别为87.5%（49/56）、69.6%（39/56）和60.7%（34/56）。结论多层螺旋CT多期增强扫描能够充分反映出小肝癌的血供特点和表现,能够实现早期诊断。

Multi slice spiral CT in the diagnosis of small hepatocellular carcinoma

Objective To study small hepatocellular carcinoma（SHCC） in L6 layer spiral CT（SCT）（during the arterial phase and portal venous phase,and theDelay period） enhanced scan features.Methods The 56 cases with pathologically proven patients with a small hepatocellular carcinoma imaging data were retrospectively analyzed.Results Patients with arterial lesions number to be significantly higher than that of the portal venous phase and delayed period（P0.01）,arterial phase sensitivity than portal venous phase and delayed phase.Small HCC lesions picks out rate was 94.6%（53 /56）,arterial,portal venous phase and delayed lesions detectable rate were 87.5%（49 /56）,69.6%（39 /56） and 60.7%（34 /56）.Conclusion Multi-slice spiral CT enhancement scanning can fully reflect the characteristics of blood supply of the small hepatic carcinoma and expression,can realize early diagnosis.
