Signal-to-noise ratio (SNR) for the consolidated lesion (a); necrotic area (b); back muscles (c) and background air (d). Figures e and f show the contrast-to-noise ratio (CNR) for consolidated lesion contrast to necrotic area (e) and back muscles (f). SNR = CT density(ROI)/SD(ROI). CNR(E) = (CT density(Lesion)–CT density(Necrosis))/SD(muscle), CNR(F) = (CT density(Lesion)–CT density(Air))/SD(Air). ※ : There is significant difference between MBIR image and other images
