Magnetic Resonance Imaging in Pediatric Bone Tumors

Abstract

The primary assessment of pediatric bone lesions is performed using radiographic imaging and is categorized according to criteria of aggressiveness. Magnetic resonance imaging plays a complementary diagnostic role in select cases, for example, when there are characteristics of fatty content, cysts with and without fluid–fluid levels, cartilaginous matrix, and low signal intensity on T2 sequences. In bone lesions presenting an aggressive pattern, MRI is the chosen method for locoregional staging and non-invasive evaluation of response to neoadjuvant treatment.
