1·Objective To study the MRI and pathological characteristics of rabbit VX2 hepatic carcinomas.
目的研究兔VX 2肝癌mri征象和癌组织病理学特征。
2·Results: 3D-CPA of hepatic carcinomas and hemangiomas have their characteristics respectively.
结果：3D-CPA可以完整立体地显示肝癌和肝血管瘤的血管特点。
3·The "pupil", " target " and " dot and color " signs shown on T2WI of the VX2 hepatic carcinomas were resulted from characteristic distribution of cancerous tissue and necrosis.
VX2肝癌在T2WI上可显示“瞳孔征”、“靶环征”和“点彩征”非均质性信号特征，组织学上为存活肿瘤组织和坏死组织特征性分布的结果；
4·Methods:5 small hepatocellular carcinomas(HCCs) and 3 hepatic metastatic carcinomas(HMCs) were performed chemo ablation of PAI under the CT guidance.
方法：5例小肝癌、3例肝转移癌在CT引导下经皮乙酸注射化学灭活术。
5·So we conclude that ADC value seems to be a promising tool for predicting and monitoring the early response to chemotherapy of hepatic metastases from colorectal and gastric carcinomas.
因而得出结论：扩散加权成像可以反应出不 同反应性胃肠癌肝转移病灶化疗前及化疗早期变化的差异，为预测及早期疗效判 断提供有益的帮助。
