Angiography has maintained a central role in the preoperative evaluation of patients with both benign and malignant tumors. A great deal of experience has accumulated with the method and the angiographic appearance of most tumors is well established. Although most cancer patients are first evaluated by less invasive techniques,angiography remains the most accurate method for the diagnosis of tumors of the liver and pancreas. In those patients in whom excision of a malignancy is considered, angiograms should be used preoperatively to assess both the resectability and curability of the lesion. In patients with carcinoma of the lung or esophagus invading the azygos vein or in patients with pancreatic carcinoma invading the visceral veins, needless radical operative procedures can be avoided. Finally, as angiographers are becoming more therapy-oriented, the palliative effects of selective arterial embolization with radioactive and infarcting materials are being evaluated.
血管造影术在良性和恶性肿瘤患者的术前评估中一直发挥着核心作用。关于该方法已经积累了大量经验，大多数肿瘤的血管造影表现也已明确。尽管大多数癌症患者首先通过侵入性较小的技术进行评估，但血管造影术仍然是诊断肝脏和胰腺肿瘤最准确的方法。对于那些考虑切除恶性肿瘤的患者，术前应使用血管造影来评估病变的可切除性和可治愈性。对于肺癌或食管癌侵犯奇静脉的患者，或胰腺癌侵犯内脏静脉的患者，可以避免不必要的根治性手术。最后，随着血管造影师越来越注重治疗，正在评估使用放射性和梗死性材料进行选择性动脉栓塞的姑息效果。
