Whole Body PET-MRI in Paediatric and Adolescent Lymphoma

Feasibility of Using Whole Body PET-MRI to Stage and Restage Paediatric and Adolescent Hodgkin Lymphoma - a Pilot Study

Children and adolescents with Hodgkin lymphoma currently undergo multiple investigations including a separate PET and MRI scans during their treatment.

Investigators want to investigate if a combined PET-MRI scan could give the same information.

Children who join our study will have an extra scan twice during their treatment

Routine whole body clinical MRI will be performed according to current clinical standard of care. Axial and coronal imaging from the maxilla to proximal femurs will be performed using a combination of T1 and T2 weighted sequences, with and without gadolinium administration.
