    Objective: Correlate the use of WB-MRI/DWI and FDG-PET/CT on children, adolescents and young adults Hodgkin Lymphoma patients, evaluating if it can be used as an alternative to ionizing radiation exams, on Hodgkin Lymphoma (HL) protocols, during staging and follow-up. Materials and methods: 33 studies from 20 HL patients from our institute, aged from 6 to 20 years old, that had both WB-MRI/DWI and FDG-PET/CT images, during a maximum of 21 day-period between acquiring those methods, were read in consensus by 2 pediatric radiologists, and classified by the presence and major extension of HL on 19 different regions. Results: The mean patients’ ages were 15.6 years old. 24.2% were staging examinations and 75.8% follow-up. The mean time between acquisitions from both methods was 7.6 days. Pearson´s (-1 to 1) correlation found r=0,831 (p<0,001) for the number of positive sites and r=0,863 (p <0,001) for their major measurements, demonstrating a statistically significant and strong positive correlation. Kappa correlation found considering FDG-PET/TC as standard was 0.08004. Conclusion: WBMRI-DWI is a safe and reliable method, with very strong Pearson correlation and almost perfect Kappa, that can be used as an alternative to FDG-PET/CT on childhood, adolescent, and young adults Hodgkin lymphoma care, helping reduce later radiation toxicity.
