摘要
目的:探讨肝细胞癌(HCC)的血供方式及CT表现。方法:回顾性分析 50例经手术、病理及临床发展过程证实的肝细胞癌的CT强化特点及征象。结果: 50例肝细胞癌平扫低密度 50例,合并高密度 5例;境界不清楚 31例,显示包膜 8例。动脉期病灶强化 46例,供瘤动脉增粗迂曲及病灶内肿瘤血管 18例,动静脉分流 10例。门静脉期病灶呈低密度 47例,血管受侵 25例;门脉癌栓 8例,伴发肝内子灶 10例;肝硬化征象 40例;肝门及腹膜后淋巴结增大 13例。结论:螺旋CT增强双期扫描技术能显示HCC病灶血供特点及较特征性的CT征象:动脉期病灶强化、供瘤血管增粗、病灶内肿瘤血管、动静脉分流、包膜、肝内子灶、血管侵蚀及静脉瘤栓、肝门及腹膜后淋巴结肿大。
Objective To study the blood suppy patterns and CT manifestations of hepatocellular carcinoma (HCC).Methods 50 cases with surgically ,pathologically and clinically proved HCC underwent spiral CT scanning (plain+dual-phase).The spiral CT contrast enhancement features were retrospectively analyzed. Results 50 cases were hypodence in plain scan,5 cases accomplied hyperdence, 31 cases diffusely infiltrating defined, 8 cases have fibrous capsule, 46 cases inhomogeneously or homogeneously enhancing,18 cases display suppying-tumour arterial and tumour vessel,10 cases arteri-venous shunt on the arterial-phase scans. 47 cases hypodence on the portal vein-phase scans,25 cases blood vessel was involved,8 cases portal vein tumor thrombi,40 cases with cirrhosis.13 cases hepatic portal and retroperitoneal lymphadenectasis.Conclusion The spiral CT dual-phase enhanced scanning can display the blood suppy features and specific CT manifestations of HCC.
