摘　　要：目的分析肝脏大血管的CT表现特征,探讨螺旋CT的诊断价值。方法回顾性研究1997年1月至2003年12月经手术、病理和随访2年以上证实的肝脏大血管69例,74个病灶。对平扫肿瘤内“更低密度区”和增强边缘“结节样强化”进行分组观察。结果CT平扫更低密度区在4.1～6cm组,6.1～8cm组和>8cm组中显示率分别为18/35(51.4%),16/21(76.2%)和18/18(100%),(P<0.01)。增强边缘结节样强化在4.1～6cm组,6.1～8cm组和>8cm组中显示率分别为26/35(74.3%),13/21(61.9%)和9/18(50.0%),(P<0.01)。结论螺旋CT对肝脏大血管瘤的诊断和鉴别诊断有重要价值。Objective The objective of our study was to evaluate the results of spiral dynamic computed to mography（CT） in the detection of gigantic cavernous hemangioma of the liver（CHL） in patients. Methods A retrospective analysis was made on 69 patients with CHL between 1997 Jan and 2003 Dec,which were indenrifled by pathologic results and evaluated for a period of more than 24 months. Hypodense in pericontrast images and peripherally nodular enhancement after inject contrast of all lesions were observed and compared. Resuits 18/35（51.4%）,16/21（76.2%） and 18/18（100%） appeared hypodense in precontrast images in 4.1-6.0cm group, 6.1-8.0cm group and 〉8.0cm group separately （19〈0.01）. Then, our study showed that the incidence of peripherally nodular enhancement after inject contrast were respectively 26/35（74.3%）,13/21（61.9%） and 9/18 （50.0%） in 4.1-6.0cm group, 6.1-8.0cm group and 〉8.0cm group （p〈0.01）. Condusions Spiral dynamic CT is a useful imaging technique for diagnosis and different diagnosis in patients with gigantic cavernous hemangioma of the liver.
