Knowledge of blood T1 and T2 is of major importance in many applications of MRI in neonates. T1 and T2 relaxometry of neonatal blood is different from that of adult, because of their differences in hemoglobin molecular structure. Using healthy cord blood samples, we established a comprehensive relationship between hematocrit, oxygenation and neonatal blood T1/T2. We found that neonatal blood has a longer T1 and T2 comparing to adult blood. The neonatal blood T1 and T2 characteristics reported in this work may serve as a useful reference for future in vivo studies aiming to assess hemodynamic function in neonates.
