Figure 4

Figure 4a is a scatter-plot demonstrating excellent correlation between ungated thoracic CT and gated cardiac CT (R = 0.98, ICC = 0.98). X-axis represents gated scores and y-axis represents ungated study score. Figure 4b is the Bland-Altman plot of the same data (Mean difference: 35 (CI −59 to 128)
