目的：探讨硬化型肝癌（SHCC）患者的 CT 及 MR 特征。方法对我院收治硬化型肝癌患者100例手术前均行 CT 或 MR 检查。结果8例 MR 平扫 T1 WI 为均匀低信号，T2 WI 为不均匀高信号，b 值为50、600s／mm2时 DWI 均为明显的高信号。增强扫描中有8例患者的肿瘤强化方式与第1种 CT 强化类型相似，肝动脉早期没有发生明显性的强化，动脉晚期出现边缘环状的强化，5例患者为薄层环状的强化，3例患者为较厚环状的强化，门静脉期和肝实质期肿瘤呈现进行性的不规则的向心性强化，瘤体较小者的肝实质期对比剂可以进行完全的填充，肿瘤呈略高信号，瘤体较大者进行延迟50min 肝胆期扫描，发现对比剂可以进一步的向病灶中心区进行填充。100个病灶为低密度，密度不均匀，42个病灶边界不清，58个病灶边界清晰。结论硬化型肝癌可呈特征性的向心性强化和类似典型结节型肝癌的表现。

Objective To investigate the CT andmagnetic resonance (MR) feature of scirrhous hepatocellular carcinoma (SHCC) .Methods 100 cases of SHCC in our hospital were all examined with CT and MR before operation .Results 8 patients showed T1 WI even low signal ,T2 WI uneven high signal on MR plain scan ,when b value was 50 ,600 s/mm2 . DWI showed apparent high signal .8 cases showed similar tumor reinforcement way in enhancement scan compared with the first CT .Hepatic did not showed apparent intensity in early period ,while edge of the ring intensity in later period .5 cases showed laminaedge of the ring and 3 cases showed thick edge of the ring .In portal venous phase and liver parenchy‐ma phase showed progressive irregular centripetal reinforcement ,patients with smaller tumor showed higher signal ,while patients with bigger tumor courage period scanning was prolonged 50 min and contrast agent moved to central lesions .100 lesions showed low and uniform density .42 cases showed unclear border and 58 cases showed clear border .Enhancement scanning : ① In hepatic arterial phase ,41 cases showed uneven enhancement edge of the ring ,and centrality to strengthen in portal vein and hepatic parenchymal phase ; ② In hepatic arterial phase ,49 cases showed unclear enhancement or uneven intensity ,while showed lange ring improving and internal space sample improving in portal vein and hepatic parenchymal phase .In hepatic arterial phase ,7 cases showed uneven light enhancement ,contrast agent flowed out quickly in portal vein and hepatic parenchymal phase .Conclusion SHCC showed distinctive centrality enhancement and similar nodular typecar‐cinomamanifestation .
