The Royal National Orthopaedic Hospital (RNOH), Stanmore, is the largest orthopaedic hospital in the UK. As a centre of excellence, many of its patients undergo numerous whole spine x-rays for spinal deformity monitoring and surgical intervention. Many adolescent scoliosis patients require whole spine x-rays on a regular basis. Until recently, we have only been able to use a digital radiography (DR) imaging system but we can now send our patients to be x-rayed using a low dose imaging (LDI) system. Armed with this technology we decided to compare the radiation dose with patients who have had a whole spine x-ray using a DR system and the same patients undergoing new whole spine x-rays using the LDI system. Previous literature only describes a comparison using LDI with phantoms.
