MR imaging of the pediatric abdomen.

MR imaging has had a major impact on pediatric abdominal imaging. It is particularly important in evaluating abdominal masses because it can provide information about resectability and extent of lesions. MR imaging is recommended over other imaging techniques for detection of vasculature encasement and intraspinal extension of tumor. The use of this imaging technique should continue to increase with the development of faster scanning sequences and contrast agents for bowel opacification.
