目的：介绍三种螺旋ＣＴ肝脏血管造影的方法，评价其对肝癌诊断的作用。材料和方法：用三种螺旋ＣＴ肝脏血管造影的方法对４９例肝癌患者作５１次检查：肝脏动脉造影ＣＴ（ＣＴＡ）、经动脉门静脉造影ＣＴ（ＣＴＡＰ）和经术中植入门静脉的药物输入系统（ＤＤＳ）直接门静脉造影ＣＴ（ＣＴＰ）。结果：这些方法可发现直径３ｍｍ的病灶，明确显示肿瘤的血供情况。结论：ＣＴＡ，ＣＴＡＰ和ＣＴＰ有利于肝脏多发和小肿瘤病灶的检出以及其鉴别诊断，ＣＴＡ和ＣＴＡＰ虽为创伤性检查，因其敏感性很高，可在肝脏肿瘤外科手术前和需明确肿瘤的血供时选用；对植入ＤＤＳ的患者，术后复查宜常规ＣＴＰ检查。
Objective: To introduce three hepatic spiral angiography methods and evaluate their role in the diagnosis of hepatocellular carcinoma. Materials and Methods: A total of 51 liver cancer patients were examined with three spiral CT hepatic angiography: hepatic arteriography CT (CTA), transarterial portography CT (CTAP), and intraoperative injection of drug input into the portal vein System (DDS) Direct portography CT (CTP). Results: These methods can find a lesion with a diameter of 3mm, clearly showing the blood supply of the tumor. Conclusion: CTA, CTAP and CTP are helpful for the detection and differential diagnosis of multiple and small lesions of the liver. CTA and CTAP are invasive examinations. Because of their high sensitivity, they can be clearly diagnosed before liver tumor surgery. When the blood supply is selected; for patients with DDS implants, postoperative review should be routine CTP examination.
