Of these, MR difusion tensor imaging and tractography may allow urther understanding of neural development and more precise definition of abnormality and pathology (Kasprian, 2008; Mitter, 2015). Automatic and semiautomated extraction of quantitative data from MR imaging volumetric acquisitions of fetal brain and placenta may enable subanalyses of massive datasets not previously possible with laborious manual segmentation (Tourbier, 2017; Wang, 2016). Using multiparametric MR of the placenta in vivo will expand our understanding of function and pathology without risk to mother or fetus. Last, although echocardiography will always be paramount in fetal heart assessment, MR imaging may contribute to volumetric cardiac analysis and will urther evaluation of the aorta, which is oten diicult to completely examine sonographically (Lloyd, 2017).
