| 目的 探讨三维动态增强磁共振血管成像(3D DCEMRA)对肝细胞癌门静脉受侵的诊断。 方法 收集经手术及病理证实的28例及临床证实的2例肝细胞癌(共30例),行MRI平扫及3D DCEMRA检查。 结果 将门静脉主干、左、右主分支分别作为一支受累血管计数, 门脉分叉部受侵按2支计数。肝细胞癌30支门静脉受累的主要表现为门静脉受压推移7支(23.3%),局部管壁浸润7支(23.3%),闭塞1支(3.3%),合并门静脉内癌栓15支(50%)。同时对肝细胞癌与肝内胆 |

| Objective To explore the manifestations of three-dimension dynamic contrast enhancement magnetic resonance angiography (3D DCE MRA) in the diagnosis of portal vein involvement with HCC. Methods Twenty-eight cases of HCC confirmed by surgery and pathology and 2 by clinic diagnosis were collected in this study. All the patients underwent the MR plain scan and 3D DCE MRA examinations. Results Left, right branch and trunk of portal vein involvement were calculated as one branch respectively for study. The 3D DCE MRA appearances of portal vein involvement in 30 branches were as follows: displacement in 7 (23.33%), infiltration in 7 (23.33%), occusion in 1 (3.33%) and cancerous thrombosis in 15 (50%). The differences between HCCs and intrahepatic cholangiocarcinoma in involvement of portal vein were also discussed. Conclusion 3D DCE MRA showed high accuracy, no damage and direction in the diagnosis of portal vein involvement with HCC, and is very important in the differentiation. It is very helpful for the selection of surgery and therapy plan in clinic. |
