| 摘 要： | 原发性肝癌是世界上最常见恶性程度最高的肿瘤之一，我国原发性肝癌患病率高于欧美及其他发达国家，严重影响了患者及其家庭的生活质量。目前，原发性肝癌的影像学检查主要有B超、CT、DSA及MR。B超价格便宜、操作简单及对软组织病变灵敏度高，但容易受到检查者经验和细致程度的限制且对早期小肝癌（直径<1 cm）诊断的准确率较低；CT有较高的空间和密度分辨率，缺点是有辐射，且时常出现假阳性；DSA为有创检查。MR成像为无创检查，且无辐射、软组织分辨率较高，可进行多参数、多方位成象及各种功能成像，在临床中应用越来越广泛，本文就MR成像技术在原发性肝癌的诊断、鉴别诊断及评价治疗疗效的应用进行综述。

| Abstract: | Primary Hepatic Caminoma is one of the most common malignant tumors in the world. The prevalence rate of our country is higher than that of Europe,the United States and other developed countries.It seriously impacts the life quality of patients and their families. At present, imaging examination of primary liver cancer mainly includes B ultrasound, CT, DSA and MR. B ultrasound is cheap, easy to operate and sensitive to soft tissue lesions. But it is limited by the experience and meticulous degree of the examiner and with less accurate for the diagnosis of early small liver cancer (diameter <1 cm). CT has a high spatial and density resolution.But CT has radiation and false positive. DSA is a invasive examination. MR imaging is non-invasive, and has no radiation with high resolution of soft tissue. It can carry out multi parameter, multi-directional imaging and various functional imaging. It is widely used in clinical application. This article reviews the application of MR imaging in diagnosis, differential diagnosis and evaluation of the therapeutic effect of primary liver cancer. |
