Magnetic resonance (MR) urography, in conjunction with traditional MR imaging sequences, offers the potential for a comprehensive evaluation of the entire urinary tract. In addition to defining anatomic form, MR imaging excels at tissue differentiation and can estimate renal function. Most importantly, this information can be obtained without ionizing radiation or iodinated contrast media. Therefore, MR urography has become of particular interest in certain populations, including children, pregnant women, and renal transplant donors and recipients. Despite the challenges inherent in imaging a dynamic system with often subtle abnormalities, recent advances in MR technology and field strength, coupled with expanding functional capabilities, promise a bright future for MR urography.
