选择性腹腔动脉造影(简称动脉造影)对原发性肝癌(简称肝癌)的定位诊断临床已证明颇有价值。根据动脉造影显示的肿瘤血管、肿瘤染色等特征,可以确定肝内肿瘤的部位、大小及肿瘤所累及的范围,从而对手术切除可能性的估计或照射野的合理定位提供了可靠的依据。以动脉造影定位放射 Selective celiac artery angiography (referred to as arterial angiography) in the diagnosis of primary liver cancer (referred to as liver cancer) has proved clinically valuable. According to the features of tumor angiography and tumor staining shown by arterial angiography, the location, size, and range of tumors in the liver can be determined, which provides a reliable basis for estimating the possibility of surgical resection or reasonably positioning the irradiation field.
