摘　　要：目的：分析比较高场强 MRI平扫及 LAVA增强序列在肝癌包膜显示中的优劣性,提高 MRI 对原发性肝癌的早期诊断及鉴别诊断的水平。方法回顾性分析233例原发性肝癌患者的 MRI 资料,由2名副主任医师以上的医生分析影像资料得出数据。结果233例原发性肝癌中,除外18例弥漫型肝癌,共发现239个病灶（小肝癌54个,结节型肝癌76个,块状型肝癌109个）。肝癌包膜显示率为58.16%（139/239）,其中T1 WI显示119个,T2 WI显示87个,LAVA增强显示139个。T1 WI 显示完整包膜25个,T2 WI显示12个,LAVA增强显示59个。小肝癌显示包膜38.9%（21/54）,结节型肝癌显示包膜69.7%（53/76）,块状型肝癌显示59.6%（65/109）。结论高场强 MRI 常规平扫及增强序列可以较好显示肝癌包膜,LAVA 增强（门脉期＋延时期）优于T1 WI、T2 WI。随着肝癌直径增加,T1 WI及T2 WI在肝癌包膜的显示方面更具优势。Objective To analyze and compare the advantages and disadvantages in high-field MRI scan and LAVA enhanced in the display of hepatic carcinoma capsule,in order to improve the early diagnosis and differential diagnosis level of primary hepatic carcinoma by MRI.Methods MRI data of 233 patients of primary hepatic carcinoma were retrospective analysed by two radiologists. Results 233 cases of primary hepatic carcinoma,except for 18 cases of diffuse hepatocellular carcinoma,a total of 239 lesions （54 small hepatocellular carcinoma,76 nodular hepatocellular carcinoma,109 massive hepatocellular carcinoma ）were found .Hepato-cellular carcinoma capsule display rate was 139/239（58.16%）.119 T1 WI,87 cases were found in T2 WI,and 139 cases were found in LAVA enhanced scan.25 lisions showed complete capsule on T1 WI,12 lisions showed complete capsule on T2 WI,59 lisions showed complete capsule on LAVA enhanced scan.Small hepatocellular carcinoma displayed capsule 21/54 （38.9%）,nodular hepa-tocellular carcinoma 53/76 （69.7%）,massive hepatocellular carcinoma 65/109 （59.6%）.Conclusion High-field MRI conventional scan and LAVA enhenced scan can display PHC capsule better,LAVA enhanced （portal phase ＋ delay phase）showed PHC capsule better than T1 WI and T2 WI.
