Paediatric abdominal computed tomography: the technique and use in neuroblastomas and pelvic masses.

Paediatric abdominal CT often has to be performed outside a children's hospital. Without careful planning, the examination can be unrewarding and full of snags, and our technique for these conditions is outlined. Some of the problems of whole body CT are discussed and the examination has been found to be of the greatest value in children with extensive retroperitoneal and pelvic masses. In these circumstances it may be used for both diagnosis and treatment follow-up, and the benefits it provides justify any increased radiation to the patient.
