Spectral or multi-energy CT (MECT), obtains raw data at more than one energy spectra which allows the decomposition of materials into their constituent elements. As opposed to conventional CT which yields data based on linear attenuation, MECT yields both structural and material-specific information. Only limited experience and literature are available regarding use and applications of MECT in the pediatric patient population. Our institution has recently installed a spectral MECT scanner which uses a single x-ray source modified multilayered detector CT, in our emergency department (ED). It is currently the only such scanner used for routine clinical pediatric imaging in the US, and 4^th such unit in a children’s hospital in the world. In this educational exhibit we will review the basic physics of MECT, the benefits and limitations of the single-source multi-layered detector geometry, and clinical applications of MECT and our experience to date in the pediatric population.

Trauma is a leading cause of death and disability in children ages 1-18, with blunt trauma causing the majority of abdominal injuries. For radiologists, cases of trauma elicit the necessity of timely reads to determine if a patient requires immediate surgical intervention, or is a candidate for conservative, non-operative management. Spectral Dual-Energy Computed Tomography (DECT) obtains raw data at two energy spectra which by virtue of material decomposition can identify, isolate and or quantify iodine, pure calcium, and uric acid. Multiple image sets can be generated from a single scan allowing both standard anatomic and material-specific analysis. This allows accurate demonstration and grading of solid organ injury, differentiation between acute hematoma from ongoing vascular extravasation, detection of subtle injuries and visualization of compromised vascular structures all of which are imperative in determining the proper course of treatment in the acute trauma setting.
