【摘要】：目的探討擴(kuò)散加權(quán)成像(DWI)技術(shù)在肝臟常見(jiàn)含脂質(zhì)腫瘤鑒別診斷中的應(yīng)用價(jià)值。資料與方法回顧分析2011年1月—2015年8月解放軍第302醫(yī)院經(jīng)病理確診的60例肝臟含脂質(zhì)腫瘤,包括25例肝細(xì)胞癌(HCC)、20例肝腺瘤(HA)、15例肝臟血管平滑肌脂肪瘤(HAML),分別測(cè)量腫瘤的表觀擴(kuò)散系數(shù)(ADC)值、ADC_(腫瘤)_/ADC(肝臟)(r ADC),并分析常規(guī)MRI表現(xiàn)。結(jié)果 3種常見(jiàn)肝臟含脂質(zhì)腫瘤的MRI表現(xiàn)各有特征,HCC、HA、HAML的平均ADC值分別為(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分別為1.004±0.151、0.984±0.146、1.027±0.223,三者間ADC、r ADC差異均無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論 ADC及r ADC在肝臟常見(jiàn)含脂質(zhì)腫瘤中無(wú)鑒別診斷價(jià)值,常規(guī)MRI及增強(qiáng)特征是診斷的主要依據(jù)。
[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.緇撴灉 3縐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鐨勫鉤鍧嘇DC鍊煎垎鍒負(fù)(1.225鹵0.221)脳10~(-3) mm~2/s,(1.318鹵0.212)脳10~(-3) mm~2/s,(1.317鹵0.297)脳10~(-3) mm~2/s(b=800 s/mm~2),r ADC鍒嗗埆涓，
