目的：探析MRI弥散加权成像联合动态增强扫描在肝脏占位性病变诊断中的运用价值。方法：选取2010年7月-2014年7月期间本院收治的肝脏占位性病变患者49例为研究对象，对其临床治疗资料进行回顾性分析。结果：所有患者均顺利完成检查，其中海绵状血管瘤具有较高的表观扩散系数，其次为肝脏转移瘤，最低为原发性肝细胞癌；肝脏恶性肿瘤与血管瘤之间的ADC值比较差异有统计学意义（P<0.05）。原发性肝细胞癌的动态增强曲线主要为Ⅰ型，10例占47.62%；肝脏转移瘤主要为Ⅱ型，9例占60.0%；肝脏海绵状血管瘤主要为Ⅲ型，9例占69.23%，且三种肝脏占位动态增强曲线类型比较差异有统计学意义（P<0.05）。DWI联合动态增强扫描的诊断准确率高于动态增强扫描。结论：临床上在对肝脏占位性病变进行诊断时，运用MRI弥散加权成像联合动态增强扫描，能够有效提高诊断准确率，值得推广应用。

Objective:To analyze the applying value of MRI diffusion weighted imaging combination with dynamic enhanced scan in the diagnosis of hepatic space-occupying lesions.Method:49 patients with liver space-occupying lesions in our hospital were selected as the research objects from July 2010 to July 2014,the clinical data of patients were retrospectively analyzed.Result:All patients were successfully completed the examination cavernous,hemangioma had high apparent diffusion coefficient,followed by liver metastases,the lowest for primary hepatocellular carcinoma(HCC). Malignant liver tumors compared with hemangioma of ADC values,the difference was statistically significant(P<0.05). The dynamic enhancement curve of primary hepatocellular carcinoma(HCC)were mainly 10 cases(47.62%)ofⅠtype, liver metastases were mainly 9 cases(60.0%)ofⅡtype,hemangiomas were mainly 33 cases(67.35%)ofⅢtype,and compared three kinds of liver placeholder dynamic contrast enhancement curve type ,the difference was statistically significant(P<0.05).The diagnostic accuracy of DWI combined with dynamic contrast-enhanced scan was higher than that of dynamic contrast-enhanced scan.Conclusion:MRI diffusion weighted imaging combination with dynamic enhanced scan in clinical diagnosis of liver space-occupying lesions can effectively improve the diagnostic accuracy rate,it is worthy of popularization and application.
