title: The Role of Computerized Tomography in the Assessment of Perivesical Invasion in Bladder Cancer.
abstract: BACKGROUND
  The aim of the present study was to identify the contrast patterns of a tumor, and to evaluate the possibility of assessing the invasion of the perivesical fatty tissue in bladder cancer.
  
  
  METHODS
  In this study, 26 patients with bladder cancer were included. Multiphasic CT examination was performed to determine the stage of the disease before radical cystectomy.
  
  
  RESULTS
  There were statistically significant differences in tumor and perivesical fatty tissue densities between pre- and post-contrast phases (p<0.05).
  
  
  CONCLUSIONS
  Increases in focal density suspected of being invasion of the perivesical fatty tissue can show perivesical invasion with high specificity.
