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.
