Table 5.

Mean Transit Time (MTT) plus or minus one standard deviation for the experiment in seconds. For α = 0.05, t_α/2 = 2.776, and |t| > t_α/2 implies statistically that the means reported by the two methods are significantly different (highlighted in bold). Key: PA - Pulmonary Artery, LL - Left Lung, RL - Right Lung, PV - Pulmonary Vein, DA - Descending Aorta
