. Although significantly less sensitive than MRI, it is easier to include more bones. A study found that MRI of just the spine and pelvis would have detected 9% fewer cases of bone involvement than the more extensive skeletal survey which therefore remains the standard method. Skeletal surveys are also used with suspected non-accidental injury in children (CE guidelines state that 19 images of the child are taken.) These are reported on by a consultant paediatric radiologist and often copies are made. Non-accidental injury is suspected if a child sustains an injury where the clinical findings are not consistent with the explanation given for the injury, such as a spiral fracture in a child who is not yet walking. A skull CT is also done in connection with the radiographs if the child is under one year old or, if the child is older, where there is a clinical requirement (perioribtal ecchymosis, for example) as to rule out
