Bland-Altman scatterplots. The intra- (upper) and inter-observer (lower) variabilities are shown for the maximum CT number (MAX), peak CT number (PEAK), difference between maximum and peak CT numbers (M-P), and mean changing velocity of M-P (V. (M-P)). SD = standard deviation. Low measurement coefficients of variation indicate good reproducibility and error control
