Whole-body (WB) magnetic resonance (MR) imaging in children is of special interest because it is radiation free and can be used to evaluate systemic conditions, exploiting the advantage of the superior soft-tissue contrast provided by MR imaging. An important clinical application of whole-body MR imaging in children is its use for screening of oncologic conditions, tumor characterization, and staging. However, the list of non-oncologic applications of WB MRI has recently expanded to include the evaluation of numerous multisystemic conditions. This is a pictorial review of different oncologic applications of WB MRI including cancer predisposition syndromes, solid neoplasias and lymphomas, as well as of non-oncologic applications of WB MRI including chronic recurrent osteomyelitis (CRMO), enthesitis related arthritis (ERA), vascular malformations and benign tumors. In this review we discuss the advantages and challenges of conventional and functional MRI sequences including the use of diffusion weighted imaging (DWI), color-encoded DWI enhanced with iron supplement Ferumoxytol as blood pool contrast agent, as well as the advantages and disadvantages of the recently introduced WB positron emission tomography (PET)/MRI.
