Vessel oxygen saturation can be determined with MR oximetry using an in vivo measurement of signal decay (T2) and the calibration curve relating T2 to blood oxygen saturation (%HbO(2)), where: 1/T2=1/T2O+K (1-%HbO(2)/100)(2) and K is a constant parameter which correlates with measured fibrinogen levels. The ability to noninvasively measure %HbO(2) in cardiac chambers and vessels has enormous potential in children with congenital heart disease (CHD). Objective: The purpose of the study was to prospectively characterize the T2-%HbO(2) relationship in infants where T2-%HbO(2) is the relationship between T2 and %HbO(2) (blood oxygen saturation) expressed by the equation given above, and to determine whether adult values for K and T2O (where T2O is the T2 of fully oxygenated blood) can be extrapolated to pediatric patients with CHD. A second objective was to apply this method to calculate the %HbO(2) in vivo using MR imaging in infants with CHD.
