THE ROLE OF MR IMAGING IN CARCINOMA OF THE URINARY-BLADDER

In this article, the role of MR imaging in the management of carcinoma of the urinary bladder is reviewed and illustrated. The appearance of the normal urinary bladder and of bladder carcinoma on MR images is shown. Important factors for optimal MR imaging of urinary bladder carcinoma are reviewed. New developments such as three-dimensional and fast spin-echo sequences and the use of contrast agents, endorectal imaging, and phased array coils are discussed. Finally, the value of MR imaging in the staging of bladder carcinoma is described, and MR staging is compared with clinical staging, staging based on findings from intravesical sonography, and CT staging.
