| Popis: | 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. |
