Thus, in the current study, we set out to compare the size-specific dose estimates (SSDE), CT dose indices ([CTDI.sub.vol], in mGy) and image quality parameters of the chest CTs obtained with FKS-DECT versus those with SECT.
* The mean size-specific dose estimates and CT dose indices of the chest CTs obtained with fast kilovoltage-switching dual-energy CT (FKS-DECT) were lower than those with single-energy CT (SECT).
* Size-specific dose estimate (SSDE) is the final dose quantity resulting from the multiplication of CTD[I.sub.vol] and a conversion factor based on patient size.

American Association of Physicists in Medicine (AAPM) has published two reports recommending the use of conversion factors corresponding to different patient size values for the determination of size-specific dose estimates (SSDE) (7, 8).
