目的：探讨螺旋 CT 动脉三期扫描联合血管造影（CTA）技术对小肝癌诊断的临床应用价值。方法回顾性分析27例经手术病理或穿刺病理确诊的小肝癌患者的 CT 资料，术前均行螺旋 CT 动脉三期扫描及血管造影 CTA 重建。结果肿瘤在动脉早期无强化13例，强化14例，其中血管样强化9例，肿瘤实质样强化5例，轻度强化8例，中度强化4例，重度强化2例；动脉中期无强化3例，强化24例，其中血管样强化16例，肿瘤实质样强化8例，轻度强化11例，中度强化4例，重度强化9例；动脉晚期均有不同程度强化，其中血管样强化4例，肿瘤实质样强化23例，轻度强化2例，中度强化5例，重度强化20例。能够充分显示小肝癌的供血血管数量及形态，动脉早期1例，动脉中期9例，动脉晚期5例。结论螺旋 CT 动脉三期扫描联合血管造影（CTA）技术对小肝癌的诊断具有重要的临床价值。

Objective To investigate the clinical value of spiral CT triple arterial phase scanning technique and CTA en‐hanced scan in diagnosis of small hepatocellular cancer .Methods CT manifestations of 27 cases with small hepatocellular cancer verified by operation and pathology were analyzed retrospectively .All the cases with small hepatocellular cancer un‐derwent Triple arterial phase scan and CTA reconstruction by spiral CT .Results 14 cases of small hepatocellular carcino‐ma were enhancement and 13 cases of small hepatocellular carcinoma were not enhancement in early arteria ,of which 9 ca‐ses were enhancement as form of blood vessel and 5 cases were whole tumor of parenchyma enhancement ,8 cases were slight enhancement and 4 cases were moderate enhancement ,2 cases were heavy enhancement ,24 cases of small hepatocel‐lular carcinoma were enhancement and 3 cases of small hepatocellular carcinoma were not enhancement in middle artery ,of which 16 cases were enhancement as form of blood vessel and 8 cases were whole tumor of parenchyma enhancement ,11 cases were slight enhancement and 4 cases were moderate enhancement ,9 cases were heavy enhancement .All cases of samll hepatocellular carcinoma were enhancement in late arterial different degree ,of which 4 cases were enhancement as form of blood vessel and 23 cases were whole tumor of parenchyma enhancement ,2 cases were slight enhancement and 5 cases were moderate enhancement ,and 20 cases were heavy enhancement .Conclusion Spiral CT triple arterial phase scanning technique and CTA play an important role in the diagnosis of small hepatocellular cancer with a high diagnostic accuracy and clinical value .
