Abstract

Magnetic resonance imaging (MRI) is an useful modality for evaluating the urogenital solid and cystic organs. The multiplanar capacity and different imaging techniques (sequences) of MRI aids in the imaging of the kidneys, the adrenal glands, retroperitoneal structures, urinary bladder, the internal and the external genital organs. Major clinical uses of MRI are in the evaluation of mass lesions, staging of urogenital cancers, characterization retroperitoneal fluid collections and assessment of vascular structures. Kidney motion, whether from respiration or other body movement, may degrade spin echo images, and inability to define calcification confidently is a significant disadvantage. The normal MRI anatomy and imaging techniques of the urogenital system were presented in this chapter. Additionally the MR urography (MRU) is a new technique which has rapid relaxation time and does not require ionizing radiation visualizing urinary system was also explained.
