摘要
目的:探讨MR扩散加权成像(DWI)及ADC值对肝脏占位性病变的诊断价值。方法:原发性肝细胞癌31例,转移瘤26例,肝血管瘤11例,肝囊肿10例,其他病变8例。进行MRI平扫及DWI。选取病灶感兴趣区,测出信号值,并计算ADC值,进行量化分析。结果:肝脏占位性病变的平均ADC值如下:肝囊肿(2.583±0.156)×10^(-3)mm^2/s,血管瘤(1.689±0.313)×10^(-3)mm^2/s,转移瘤(1.021±0.213)×10^(-3)mm^2/s,原发性肝细胞癌(1.031±0.262)×10^(-3)mm^2/s。肝脏良性病变的ADC值明显高于恶性肿瘤,并有显著性差异(P<0.05)。结论:通过对肝脏不同病变的ADC值进行量化分析,能为肝脏占位性病变的定性诊断提供重要依据。
Objective：To study the applied value of MR DWland ADC value of in the hepatic lesions.Methods：31 eases of hepatocellular carcinoma,26 cases of metastases, l 1 cases of hepatic cavemous hemangioma and 10 cases of cystwere examined by DWI and conventional MRl,then measured the signal and caculated the ADC.Results：The average ADC values of hepatic lesionswere as follows：cystwas （2.583±0.156）×10-3mm2/s,hemangioma was （l.689±0.156）×10-3mm2/s,metastases was（l.021±0.156）×10-3mm2/s;hepatoceUular carcinoma was（1.031 a：0.262）~ 10-3mm2/s.The ADC values of benign lesionswere higher than those of malignant （P〈0.05）.Conclusion：The ADC valuesmay help in differentiating benign from malignant hepatic lesions.
