This may induce misdiagnosis-based treatment initiation, but only for a relatively small percentage of approximately 10% of non-Wilms tumors (non-WTs). MRI could be useful for reducing misdiagnosis, but there is no global consensus on differentiating characteristics.<h4>Purpose</h4>To identify MRI characteristics that may be used for discrimination of newly diagnosed pediatric renal tumors.<h4>Study type</h4>Consensus process using a Delphi method.<h4>Population</h4>Not applicable.<h4>Field strength/sequence</h4>Abdominal MRI including T1- and T2-weighted imaging, contrast-enhanced MRI, and diffusion-weighted imaging at 1.5 or 3 T.<h4>AssessmeJournal of magnetic resonance imaging : JMRIMRI Characteristics of Pediatric Renal Tumors: A SIOP-RTSG Radiology Panel Delphi Study.PMC9291546341Di Paolo PLLakatos KGraf NMentzel HJCalareso GGranata CGavra MMOlsen OEVult von Steyern KMorosi CVarga ENievelstein RAJSchenk JPvan den Heuvel-Eibrink MMKyncl MBreysem LSchafer JFComa ALederman HMBrisse HJDucou Le Pointe HHotker AMAertsen MLequin MHLittooij ASWatson TASwinson Sde Krijger RRvan der Beek JNfalseMRI Characteristics of Pediatric Renal Tumors: A SIOP-RTSG Radiology Panel Delphi Study.<h4>Background</h4>The SIOP-Renal Tumor Study Group (RTSG) does not advocate invasive procedures to determine histology before the start of therapy.
