Aims and objectives
- The accuracy of initial staging is critically important because of the further differences in the intensity,
duration of the therapy and the prognosis of the disease.
- Initial stage of paediatric HL depends on the spread of the lymphomatous process and determined by diffrent imaging modalities (conventional contrast-enhanced (CE) computed tomography (CT),
18F-Fluorodeoxyglucose (18F-FDG) PET/CT).
- At a present time,
there is no commonly accepted diagnostic algorithm for staging pediatric HL.
- Children with HL sequentially undergo a lot of unnecessary scanning (for example,
enhanced CT followed with 18F-FDG PET/CT)
- Overscanning of pediatric patients leads to the increasing cumulative radiation dose and associated with the risks of carcinogenic effects
The purpose of this study was to assess and compare the role of 18F-Fluorodeoxyglucose (18F-FDG) PET/CT and conventional contrast-enhanced (CE) CT in the initial staging of HL in children and adolescents.
