Multiple MRI quantitative techniques have confirmed that postnatal brain development is an ongoing maturation process. Fetal brain development is an ongoing process.  In this work, T1Mapping allowed quantitative assessment of fetal brain development.
T1Mapping maps in the fetal brain (A–D). Examples of ROIs for DTI are shown in white color (1–2). The area of the ROI was adjusted appropriately according to the gestational week and anatomical structures. Regions of interest: 1, Thalamus; 2, Corticospinal fibers. A and B are T1Mapping images of the same fetus; And gestation ages was 28 week. C and D are T1Mapping images of the same fetus; And gestation ages was 36 week.
T1 relaxation time trajectories in Thalamus for 17 subjects. T1 had good correlation with gestational age. A regression line is shown along with 95% confidence intervals (dotted lines).
