摘　　要：目的：评价肝脏螺旋ＣＴ动脉造影（ＳＣＴＡＬ）对肝肿瘤的诊断价值。方法：对２０例肝细胞性肝癌（ＨＣＣ）和１０例肝内转移癌患者作ＳＣＴＡＬ：经皮穿刺肱动脉，将５－ＦＣｏｂｒａ导管送入肝动脉，以０．３～１．５ｍｌ／ｓ的速度经导管注入浓度为３００ｍｇＩ／ｍｌ的造影剂１５～３０ｍｌ，在开始注入造影剂６～１０ｓ后用螺旋ＣＴ行全肝扫描。结果：所有肿瘤病灶均显著增强，肿瘤的实体部分ＣＴ值为１０５～４１３ＨＵ，明显高于邻近肝组织。ＨＣＣ灶多呈不均匀增强，转移灶多呈环形增强，而直径为３～１０ｍｍ的病灶呈均匀增强。结论：与常规肝脏ＣＴ增强扫描相比，ＳＣＴＡＬ可发现更多的多血供病灶，能真实显示肝肿瘤的肝动脉血供情况。Odjective:To evaluate the value of spiral computed tomographic arterography of the liver (SCTAL)for diagnosis of hepatic neoplasms.Methods:Thirty patients with liver neoplasms were underwent SCTA,including 20 cases of hepatocellular carcinoma (HCC)and 10 cases of metastasis.A 5-French Cobra catheter was inserted into hepatic artery through brachial,then 15-30ml of 300mg I/ml contrast medium was injected into the catheter at speed of 0.3ml-1.5ml/s,and the whole liver was scanned with spiral CT,starting at 6-10sec from beginning of injection. Results:The all liver neoplasms were enhanced significantly,the CT attenuation value of their solid parts being 105-413 HU,much more higher than that of the surrounding liver tissue.In general,the lesions of HCC were enhanced heterogeneously;the lesions of matastasis demonstrated ring-like enhancement;and the lesions of 3-10mm in diameter were enhanced homogeneously. Conclusion:SCTAL can find more hypervascular lesions than conventional enhaned CT of the liver and can actually demonstrate blood supplying condition of hepatic artery for hepatic neoplasms.
