Table 1.
Mean R values from all bed positions that satisfied the condition Rt = 240 ≥ 15
Scan duration (s) | 10 | 20 | 30 | 40 | 50 | 60 | 80 | 100 | 120 | 180 | 210 | 240 |
---|---|---|---|---|---|---|---|---|---|---|---|---|
Mean R [for Rt = 240 ≥ 15] |
7.8 | 10.6 | 12.8 | 14.3 | 15.2 | 16.3 | 17.3 | 18.2 | 18.7 | 20.1 | 21.0 | 21.7 |
A systematic reduction in the R value is seen for when the acquisition duration is reduced. All of the mean values are significantly lower than the mean value from 240 s of data (paired t test; p < 0.01)
