Table 5. Mean CT Number (HU) by reconstruction technique and location.
Location | RD-FBP | RD-ASIR | RD-PICCS |
---|---|---|---|
Liver | 79±25 | 79±25 | |
Kidney | 97±67 | 97±67 | 97±67 |
Fat | −100±14 | −100±14 | |
Muscle | 54±14 | 54±14 | 55±14 |
All numbers are expressed in Hounsfield units (HU). RD=Reduced dose, FBP=Filtered back projection, ASIR=Adaptive statistical iterative reconstruction, PICCS=Prior image constrained compressed sensing.
