Purpose: To compare the diagnostic accuracy and clinical utility of whole-body MRI (WB-MRI) with PET/CT for oncologic surveillance in pediatric malignancies.
Methods: In 45 pediatric patients undergoing follow-up for lymphoma or sarcoma, WB-MRI and PET/CT findings were compared with histopathology or clinical follow-up.
Results: WB-MRI demonstrated sensitivity and specificity of 91% and 88%, respectively, compared with PET/CT (94% and 90%). WB-MRI avoided ionizing radiation and detected additional marrow lesions in 12% of cases.
Conclusion: WB-MRI provides a reliable, radiation-free alternative to PET/CT for pediatric oncology surveillance, supporting its integration into long-term follow-up protocols.
Keywords: Whole-body MRI, PET/CT, pediatric oncology, radiation-free imaging
