Abstract:
:The multiplanar and soft-tissue capabilities of MR imaging make it a valuable diagnostic tool for the retroperitoneal space and its organs. In addition, by virtue of its location, the retroperitoneum is well suited for study by this modality. Appropriate techniques, including the use of contrast, are discussed as are the normal and pathologic appearances of the organs and areas of the retroperitoneum.
