Bodanapally UK, et al. - This retrospective study evaluated the hemorrhagic progression of contusion rates on 120-kV and 190-keV images derived from dual-energy CT and the magnitude of hematoma volume overestimation. As per the data, the 120-kV images, which appeared to be comparable with single-energy CT images, considerably overestimated the hematoma volumes, hence the rate of hemorrhagic progression of contusions, after contrast-enhanced whole-body CT. The follow-up of hemorrhagic contusions was recommended on dual-energy CT, and the use of 190-keV images was suggested for the analysis of hematoma volumes.
