Synopsis

The value of non-parallel-transmission zoom-diffusion weighted imaging (non-PTX zoom-DWI) compared with conventional DWI in the diagnosis of bladder cancer muscular invasion is investigated. Results show that non-PTX zoom-DWI improves sensitivity, specificity, positive predictive value, negative predictive value, and accuracy. Additionally, it has good diagnostic consistency across different readers, and shows better display of bladder than conventional DWI sequence. Non-PTX zoom-DWI may be superior to conventional DWI in predicting the muscular invasion in bladder cancer.
