Study of high-field MRI in primary hepatic carcinoma capsule / 实用放射学杂志

ABSTRACT

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.
