Imaging of patients with Wilms' tumor.

Continued advances in imaging technology have improved the ability to detect Wilms' tumor and its precursor, nephroblastomatosis, as well as tumor spread to other organs in a less invasive manner than in years past. However, there is still wide variation in clinical practice in the imaging of this tumor compared with the guidelines set forth by the National Wilms' Tumor Study Group. This article reviews current imaging options and recommendations for the evaluation of children with Wilms' tumor as well as for surveillance of children with associated disorders such as hemihypertrophy.
