Mean SUV of liver (a), soft tissue (c), soft tissue in beam hardening region (e) and maximum SUV of the lung lesion (g) for each TR. The values from the RR are indicated by the dashed black line, and 1 standard deviation below the mean of the RR SUV is indicated by the dot dash black line (not applicable for the maximum SUV of the lung lesion). Mean SUV of liver (b), soft tissue (d), soft tissue in beam hardening region (f) and maximum SUV of the lung lesion (h) for each CT test reconstruction relative to CTDI. Shaded areas indicate confidence limits based on locally weighted regression fitting [22]
