Variation in K i due to respiration. The percentage difference between the true and measured K i2 (dark grey bars) and K iP (light grey bars) in each of the different TTAC configurations where I, E and M represent ungated PET data reconstructed with an end inspiration, an end expiration and a mid-breathing cycle ‘snap shot’ CT for AC respectively (i.e. IEM = the early study section PET data were reconstructed with an end inspiration CT for AC, the mid section with an end expiration CT for AC and the late section with a mid-breathing cycle CT for AC)
