Unfortunately, DTI presents an even bigger challenge for in utero fetal imaging relative to other techniques since acquisition times are longer and therefore studies are more susceptible to motion artifacts. Consequently, only a few recent studies provide quantitative data from in utero studies of neuronal pathways. As an example, Kasprian et al.  examined a group of fetuses ranging in age from 18 to 37 weeks and reported that only in 40 % of examined fetuses, DTI measurements were robust enough to successfully calculate and visualize bilateral, craniocaudally 30 A.
Diffusion weighted imaging (DWI) was performed in 48 non-sedated third trimester fetuses with normal structural MRI results. ADC was measured in white matter (frontal, parietal, temporal, and occipital lobes) by progressive myelination. However, the relationship between ADC and GA appears to be region dependent and nonlinear. Thus, in a study of 50 normal fetuses between 19 and 37 weeks’ gestation, ADC values remained constant in the basal ganglia, frontal, parietal, temporal, and occipital white matter and in the centrum semiovale while significant decreases were observed in the cerebellum, pons, and thalamus with advancing gestational age .
