Abstract:
Objective To investigate the clinical value of diffusion weighted imaging (DWI) in diagnosis of atypical cancerization nodules (CNs) of liver cirrhosis. Methods Totally 34 patients with atypical CNs of liver cirrhosis confirmed pathologically underwent routine MR, dynamic enhancement, and DWI (b=0, 500, 1000 s/mm~2). The detection rate of CNs of liver cirrhosis between routine MR and DWI was compared. Results Totally 21 patients with 28 cancerization nodules were diagnosed with routine and dynamic enhancement MR, while 27 patients with 37 cancerization nodules were detected with DWI. Significant difference was found in the detection rate between routine scan and DWI (P=0.025). Conclusion DWI shows more advantage than routine and dynamic enhancement MR for detection of liver cirrhosis with atypical CNs.
