螺旋CT薄层动态增强扫描对小肝癌的诊断价值

The diagnosis value of small hepatocellular carcinoma with spiral CT dynamic contrast-enhanced Scan

目的探讨原发性小肝癌的螺旋CT薄层动态增强扫描特征及其诊断价值。方法回顾性分析28例经临床及手术病理证实的原发性小肝癌薄层动态增强表现。结果28例共发现42个病灶,病灶位于肝左叶12个,右叶27个,尾状叶3个。平扫呈低密度或等密度;肝动脉期90%强化,10%无明显强化;门静脉期88.1%呈低密度或稍低密度,病灶密度呈速升速降的变化特点。结论螺旋CT薄层动态扫描可充分反映原发性肝癌的特征,对肝癌的检出和定性准确率的提高有重要价值。

Objective To investigate diagnosis value of multiphase spiral CT scanning for diagnosing small hepatocellular carcinoma（SHCC）.Methods CT findings of 28 patients with small hepatocellular carcinoma（SHCC） of the skull confirmed by operation and pathology underwent plain and enhanced CT scans were retrospectively sdudied.Results 42 lesions were detected totally,t he speciality of small hepatocellular carcinoma dynamic enhanced findings were ＂fast-in fast-out＂.Conclusion The multiphase spiral CT is of important value in the early diagnosis of SHCC.
