Abstract:
Objective To explore the value of DWI (diffusion weighted imaging,DWI) in diagnosis of bladder cancer in clinical T stage by comparing DWI and CT.Methods Seventy-five patients with bladder cancer underwent MRI plain scan,enhanced diffusion-weighted imaging and CT scan,to make a diagnosis preoperative clinical T stage according to their image.Then we compared the diffusion-weighted imaging and CT results with pathological staging results to assess the value of DWI in bladder tumor staging.Results For clinical T staging bladder cancer,the diagnostic accuracy rate was 83.5％ and 72％ for DWI and CT,resectively,statistical analysis showed a significant difference (P ＜0.05).Conclusion Magnetic resonance diffusion weighted imaging can accurately diagose the clinical T stage of bladder cancer,and has a higher value than CT.
