【摘要】：目的探讨扩散加权成像(DWI)技术在肝脏常见含脂质肿瘤鉴别诊断中的应用价值。资料与方法回顾分析2011年1月—2015年8月解放军第302医院经病理确诊的60例肝脏含脂质肿瘤,包括25例肝细胞癌(HCC)、20例肝腺瘤(HA)、15例肝脏血管平滑肌脂肪瘤(HAML),分别测量肿瘤的表观扩散系数(ADC)值、ADC_(肿瘤)_/ADC(肝脏)(r ADC),并分析常规MRI表现。结果 3种常见肝脏含脂质肿瘤的MRI表现各有特征,HCC、HA、HAML的平均ADC值分别为(1.225±0.221)×10~(-3) mm~2/s、(1.318±0.212)×10~(-3) mm~2/s、(1.317±0.297)×10~(-3) mm~2/s(b=800 s/mm~2),r ADC分别为1.004±0.151、0.984±0.146、1.027±0.223,三者间ADC、r ADC差异均无统计学意义(P0.05)。结论 ADC及r ADC在肝脏常见含脂质肿瘤中无鉴别诊断价值,常规MRI及增强特征是诊断的主要依据。
[Abstract]:Objective to evaluate the value of diffusion-weighted imaging (DWI) in differential diagnosis of common lipids containing liver tumors.Materials and methods 60 cases of lipids with lipids in 302 Hospital of PLA from January 2011 to August 2015 were retrospectively analyzed.Twenty cases of hepatic adenoma and 15 cases of hepatic angiomyolipoma were included in this study. The apparent diffusion coefficient (ADCC) of the tumor was measured and the normal MRI findings were analyzed.缁撴灉 3绉嶅父瑙佽倽鑴忓惈鑴傝川鑲跨槫鐨凪RI琛ㄧ幇鍚勬湁鐗瑰緛,HCC,HA,HAML鐨勫钩鍧嘇DC鍊煎垎鍒�涓�(1.225卤0.221)脳10~(-3) mm~2/s,(1.318卤0.212)脳10~(-3) mm~2/s,(1.317卤0.297)脳10~(-3) mm~2/s(b=800 s/mm~2),r ADC鍒嗗埆涓，
