title: [MR hydrography of the abdomen: technical consideration of data acquisition and future prospects for clinical applications].
abstract: Recent advances in MR hydrography have enabled various clinical applications in the areas of abdominal and pelvic disorders, for example, MR cholangiopancreatography (MRCP), MR urography(MRU), and MR hydrography of the fetus. Although the two-dimensional(2D) single-slice method provides excellent information as to the global relationship between lesions and various anatomical structures, small lesions or detailed anatomical characteristics may not be visualized owing to the partial volume effect. Source images of the 2D multislice method are most suitable for the detection of small lesions and detailed evaluation of anatomical structures as "tomographic imaging", while the three-dimensional(3D) method is useful in obtaining data sets for 3D imaging. MR hydrography is a promising method for the noninvasive evaluation of various abdominal disorders, and it has the potential to play new roles in various anatomical regions. However, knowledge of the proper indications is essential for successful clinical application.
