Going to hospital and undergoing imaging procedures can be a very harrowing and scary experience for any patient. For paediatric patients, the level of anxiety can be even greater as they do not have the years of knowledge and experience that can help some adult patients. The machine makes strange noises and looks alien. The room looks stark and sterile. And the smell of hospital disinfectant pervades. They may also be feeling unwell and have worried parents with them. Getting them to go into a scanner and, once in, to relax, stay still, and follow the technologist directions can often be challenges that are insurmountable. This can result in sedation of the patient.
