| 目的 总结原发性肝癌的MRI征象,分析其与肝癌转移之间的相关性。方法 收集我院经病理确诊为原发性肝癌的患者500例,分别行平扫、Gd-DTPA及SPIO增强扫描。结果 小肝癌65例(13％),结节型81例(16.2％),块状型325例(65％),弥漫型29例(5.8％)。多发肿瘤190例(38％)。淋巴结转移率为12％;静脉癌栓为31.4％ 。结论 原发性肝癌的MRI征象中大病灶、多病灶、T1信号不均匀者发生转移的几率较大,而四种转移形式之一均提示其他转移的几率增加。 |

| Objective To summarize the manifestation of primary hepatic carcinoma (HCC) on MRI and analyse the correlation between manifestation of HCC on MRI and HCC metastases. Methods Five hundred patients who were diagnosed as primary hepatic carcinoma histology were collected. Plain and Gd-DTPA or SPIO-enhanced MRI were performed. Results There were 65 small hepatic carcinoma (13%), 81 nodular lesions (16.2%), 352 lump lesions (65%), 29 diffused lesions (5.8%). In the 500 cases, 190 showed multiple lesions (38%). 12% were associated with lymph nodes metastases and 31.4% were accompanied with vascular invasion. Conclusion In the manifestation of HCC on MRI, multiple and big lesions with uneven intensity indicated higher possibility of metastases. Once one of the four metastases patterns occurred, it suggested the higher possibility of the other three patterns metastases. |
