Purpose: The purpose of the study was to evaluate interobserver agreement (IOA) and accuracy of magnetic resonance imaging (MRI) diagnosis of pediatric solitary liver lesions (PSLLs).
Methods: Fifty consecutive MRIs performed for PSLLs were reviewed to assess IOA and agreement between consensus imaging diagnosis and final diagnosis indicating accuracy using kappa statistics.
Results: In 39/50 cases, the MRI diagnosis given by two readers matched with substantial IOA (kappa=0.7294). There was moderate agreement (kappa=0.60784) between consensus imaging diagnosis and the final diagnosis in 10 cases with available pathology.
Conclusion: Based on the limited available pathology and follow-up, we found that most PSLLs can be noninvasively characterized and accurately diagnosed using MRI.
