对１２６例原发性肝癌与３７例转移性肝癌介入治疗前均进行了Ｂ超、ＣＴ与数字减影血管造影（ＤＳＡ）检查。ＤＳＡ显示原发性肝癌多数血供丰富，而转移性肝癌以少血供者为主；ＣＴ显示小病灶的敏感性稍差，病灶的密度和均匀性与血供多少有一定关系，但特异性不高，而病灶的增强效应与血供关系密切，多血供者中９５％有明显的增强效应，少血供者仅占４．７％；Ｂ超所示病灶的回声高低与血供亦有一定关系，但特异性稍差。结果表明，ＤＳＡ可清楚显示肝癌病灶的情况，ＣＴ所示病灶增强效应的强弱可反映出病灶血供的多少。
B-mode ultrasound, computed tomography and digital subtraction angiography (DSA) were performed on 126 cases of primary liver cancer and 37 cases of metastatic liver cancer before interventional therapy. DSA showed that most of the primary liver cancer was rich in blood supply, whereas metastatic liver cancer was mainly donated by a small number of donors. CT showed that the sensitivity of the lesion was slightly worse, and the density and uniformity of the lesion had some relationship with the blood supply, but the specificity Not high, and the enhancement effect of the lesion is closely related to the blood supply, 95% of the multi-donor have obvious enhancement effect, only 4.7% of the less blood donors; the echogenicity and blood supply of the lesion A certain relationship, but less specific. The results show that, DSA can clearly show the situation of liver cancer lesions, CT enhancement of the lesion showed the strength of the lesion can reflect the number of blood supply.
