Abstract:

Background/Objective: The purpose of this study was to evaluate the accuracy of MRI in staging bladder cancer in a series of patients with pathologically proven bladder cancer. "nPatients and Methods: Eighty-six patients with pathologically proven bladder cancer underwent MRI in Hazrat Rasoul Akram University-Affiliated Hospital from 1387-88. Pathological staging was the golden standard for determination of superficial and invasive tumors and MRI staging was compared with pathology."nResults: MRI accuracy, sensitivity, specificity, positive predictive value and negative predictive value were 94.2%, 97.7%, 90.7%, 91.3% and 97.5%, respectively. Overall agreement between MRI and pathology for bladder cancer staging was 82%."nConclusion: MRI shows goods reproducibility for bladder cancer staging especially in stage T4. More future studies are necessary for judgement.
