Using Computed Tomography skeletal surveys to evaluate for occult bony injury in suspected non-accidental injury cases - A preliminary experience.

The radiation dose received by the ten infants in this study was greater than the two skeletal survey approach but was less than the dose received during a bone scintigraphy examination, sometimes used to assess for occult bony injury in this setting. While CT-SS imaging results could not be compared with those obtained with current contemporaneous gold standard imaging techniques, CT-SS identified all fractures observed on the radiographic images where performed. CT-SS also identified additional rib fractures in two patients. Our preliminary findings indicate the need for future prospective studies to clarify the ability of CT-SS to detect metaphyseal fractures reliably.
