目的探讨螺旋CT三期动态增强扫描小肝癌的影像学特点,总结其诊断应用价值。方法回顾性分析27例经病理证实的小肝癌患者的临床及CT扫描资料。结果 27例均为单发病灶,平扫期多为低密度灶,动态增强扫描呈现均匀或不均匀强化,动脉期及门脉期则多见强化。结论小肝癌螺旋CT三期动脉增强扫描具有特征性的影像学特点,可以为其早期定性诊断提供依据,以提高临床疗效,改善患者预后,降低死亡率。
Objective To investigate the imaging characteristics of three-phase dynamic contrast-enhanced helical CT in the diagnosis of small hepatocellular carcinoma (HCC) and to summarize its diagnostic value. Methods Retrospective analysis of 27 cases of pathologically confirmed small hepatocellular carcinoma in patients with clinical and CT scan data. Results All the 27 cases were single lesion. Most of the lesions were low-density lesions during the scanning period. The dynamic contrast-enhanced scanning showed uniform or uneven enhancement, while the arterial and portal venous phases were more common. Conclusions The three-phase spiral CT enhanced arteriography of small hepatocellular carcinoma has characteristic imaging features, which can provide a basis for its early qualitative diagnosis to improve the clinical curative effect, improve the prognosis of patients and reduce the mortality rate.
