目的：探究MRI扩散加权成像对肝脏常见肿瘤的临床应用价值。方法选择我院收治的常见肝脏肿瘤患者64例，22例肝细胞肝癌，11例肝转移瘤，14例肝囊肿，17例肝血管瘤。经MRI扩散加权扫描后行全肝动态增强扫描，以扩散系数值（b值）测量并形成表观弥散系数（ADC）图，分析不同b值时良恶性肿瘤测量参数的差异。结果与肝细胞肝癌、肝转移瘤的ADC值相比，肝囊肿、肝血管瘤的ADC测定值更高，对比具统计学意义（P<0.01）。肝囊肿的ADC值高于肝血管瘤，对比差异具统计学意义（P<0.05）。结论 MRI扩散加权成像可以提高肝脏常见肿瘤的诊断敏感度，具有重要的临床应用价值。

Objective To explore the clinical application value of MRI diffusion weighted imaging in the common liver tumors.Methods Sixty cases of liver cancer patients,22 cases of liver cel carcinoma,11 cases of liver metastasis,14 cases of hepatic cysts,17 cases of hepatic hemangioma. By MRI diffusion weighted scans were performed with dynamic whole liver enhancement scanning,to the diffusion coefficient values(b)measurement and the formation of the apparent diffusion coefficient(ADC),analysis the difference of benign and malignant tumors of the measurement parameters of different b values.ResultsCompared with the ADC value of liver cel carcinoma and liver metastasis,the ADC values of hepatic cyst and liver hemangioma were significantly higher than that of,which was statisticaly significant(P< 0.01). The ADC value of hepatic cyst was higher than that of hepatic hemangioma,and the difference was statisticaly significant(P< 0.05).Conclusion MRI diffusion weighted imaging can improve the diagnostic sensitivity of common liver tumors,and has important clinical value.
