Sellerer T, et al. - Researchers intended to evaluate imaging performance across dual-energy CT (DECT) platforms, including dual-layer CT (DLCT), rapid-kVp-switching CT (KVSCT) and dual-source CT (DSCT). They found noticeable performance differences between investigated DECT systems. Across all DECT systems, iodine concentrations and virtual-monoenergetic images (VMI) hounsfield units (HUs) were accurately determined. When compared with DSCT for investigated scenarios, KVSCT and DLCT delivered slightly more accurate iodine concentration values. In DLCT, low-noise and high-image contrast at low VMI levels could help to increase diagnostic information in abdominal CT.
