Magnetic resonance diffusion-weighted whole-body imaging (DWIBS) in the urinary bladder cancer diagnostics

Abstract

The purpose of the article is to identify the most characteristic and significant changes of magnetic resonance indicators in patients with the urinary bladder cancer during diffusion-weighed whole-body imaging (DWIBS). Materials: From September 2009 till April 2011 98 patients have been examined: 61 (62.2%) with morphologically verified bladder cancer and 37 (37.8%) with cystitis. Results: The study has revealed that the sensitivity of DWIBS investigation in detecting bladder cancer is 98.36%, specificity is 10.81, and the efficacy is 65.38%. Conclusions: DWIBS is an informative noninvasive method for screening diagnostics of bladder cancer, as well as for identificating suspicious areas of regional and distant metastases.
