Table 3 First-pass PET estimates of left and right ventricular volume and function at rest and after pharmacological stress. LV was segmented using a 30% threshold. The bias (difference between stress and rest value) is given along with its 95% confidence interval

From: Feasibility of biventricular volume and function assessment using first-pass gated 15O-water PET
