ABSTRACT
Purpose To investigate the application value of diffusion weighted imaging (DWI) in differential diagnosis of common liver lipid-containing tumors.Materials and Methods Sixty patients with pathologically confirmed liver lipid-containing tumors from January 2011 to August 2015 were retrospectively analyzed,including 25 cases ofhepatocellular carcinoma (HCC),20 cases of hepatic adenoma (HA) and 15 cases of hepatic angiomyolipoma (HAML).Apparent diffusion coefficient (ADC) value and ratio of ADCtumor/ADCliver (rADC) of tumors were respectively measured.Routine MRI findings were analyzed.Results The MRI findings of these three common liver lipid-containing tumors were with their own characteristics.For HCC,HA and HAML,the average ADC value was (1.225±0.221)×10-3 mm2/s,(1.318±0.212)×10-3 mm2/s and (1.317±0.297)×103 mm2/s,respectively,(b=800 s/mm2);the average rADC value was 1.004± 0.151,0.984 ± 0.146 and 1.027±0.223,respectively.There was no significant difference in ADC and rADC among these three tumors (P>0.05).Conclusion ADC and rADC had no differential diagnosis value in common liver lipid-containing tumors.Routine MRI signals and enhanced imaging features are the main diagnostic basis.
