摘　　要：目的探讨螺旋CT多期增强扫描对小肝癌诊断的临床价值。方法回顾性分析75例确诊为小肝癌患者的临床资料,所有的病例行螺旋CT多期增强扫描,时间分别为动脉期25～35s,门脉期60～80s,延迟期4～6min,经静脉以2.5～3ml/s的速率高压注射造影剂80～95ml,观察小肝癌在不同时期的强化情况。结果共检出84个病灶,动脉期、门脉期以及延迟期的检出率分别是90.48%、71.43%和69.05%,而且动脉期检出的病灶数明显多于门脉期和延迟期(P<0.01)。结论螺旋CT多期增强扫描使小肝癌呈现典型的表现,提高了诊断与鉴别诊断能力及小肝癌的检出准确性。Objective To explore clinical value of the diagnosis of small hepatic cellular carcinoma with multi-phase enhanced helical computed tomography. Methods We retrospective analyzed 75 small hepat- ic cellular carcinoma patients＇ clinical data. All patients underwent multi-stage enhanced helical computed tomo- graphy, scan time of the arterial phase was 25 -35 s, the portal venous phase was 60 ~ 80 s, and the delay phase was4 - 6 min. The.. contract of 80 ~ 95 ml was intravenously injected at a velocity of 2. 5 ~ 3 ml/s with a high pressure syringe, and observed the enhancement condition of SHCC at different phases. Results In 84 le- sions, the arterial phase, portal venous phase, delay phase of the detection rate of 90.48% ,71.43% and 69. 05%, and the number of lesions detected by the arterial phase was significantly more than the portal venous phase and delay phase（P 〈 0. 01 ）. Conclusion Multi-phase enhanced helical computed tomography showed typical performance, improved the detection accuracy of small hepatic cellular carcinoma and the diagnosis and differential diagnosis capability.
