Abstract
Summary and Conclusion Hepatocellular carcinoma (HCC) is considered to be the most common primary cancer of the liver. It is the second leading cause of cancer death worldwide(1)In the intermediary stages, which make up approximately one third of the patients at the time of diagnosis, the recommended treatment is chemoembolization(100). Chemoembolization is based on the principle of intra-arterial injection of an antineoplastic agent, followed by occlusion of the artery or arteries, which supplies the tumor(s). In order for the treatment to be effective, it is essential that it is injected into the artery or arteries, which supply the tumor(s). These arteries must be identified by imaging in the pre-treatment assessment.DSA was the main imaging method for detecting feeding arteries of HCC including HA and ectopic blood supply. Its application is limited due to the invasiveness, the cost and also the inability to identify all possible blood vessels during the examination(13). Modern non-invasive diagnostic imaging techniques such as MDCT have replaced conventional angiography for displaying hepatic and perihepatic vessels and determination of the tumor feeding vessels before TACE(13). This study included 50 patients presented to radiology and oncology departments with HCC for CECT abdomen assessment.
