摘要：
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.
