Problems in the imaging of three common paediatric solid tumours.

Modern radiologic techniques have led to a more accurate diagnosis and staging in many paediatric malignancies. The optimal imaging of some tumours is not, however, well defined and needs to be constantly re-assessed. Similarly with evolving clinical treatment protocols, recommended imaging strategies should be continually re-evaluated. The significance of some findings on radiologic examinations in paediatric oncology patients is disputed. A number of issues relating to the imaging of Wilms', neuroblastoma and rhabdomyosarcoma in childhood are discussed.
