Bladder cancer is the most common malignant tumor of the urinary tract. It accounts for approximately 8% of all male cancers and 3% of all female cancers (Boring et al., 1993). The mean age of incidence of bladder cancer in Egypt is 46 years with a peak incidence in the fifth decade (El-Bolkainy et al. 1972).The aim of this study was to evaluate the usefulness of MRI in the staging of urinary bladder carcinoma and to correlate between the diagnostic accuracy of MRI and pathological staging. This pretherapeutic staging of the urinary bladder neoplasms is of great value to choose the best therapeutic modality before proceeding into surgery, chemotherapy or radiotherapy; as well as anticipating the patients’ prognosis.
