Visualization of objective image measurement: examples with one circular ROI (segmental pulmonary artery—peripheral) in upper row and two circular ROIs (main pulmonary artery—central and muscle) in lower row, which were defined at the same position for all reconstructed images (FBP; ASiR-V 30%, 60% and 90%; DLIR in low (L), medium (M) or high (H) strengths) per patient.
