Image quality comparison for ULD CT: hybrid versus pure IR. ULD CT coronal (3-mm thickness) images reconstructed with hybrid IR (a) and pure IR (b). Representative axial (3-mm thickness) images at five anatomical levels (1, head; 2, neck; 3, thorax; 4, abdomen; 5, pelvis) are shown for hybrid IR (left) and MBIR (right). Images were visualised using soft-tissue window settings (window width 400 HU; window level 40 HU).
