TLDR
The common clinical conditions imaged by fetal MRI as well as recent advances in fetal MRI research are discussed.
Abstract
Fetal MRI is clinically performed to evaluate the brain in cases where an abnormality is detected by prenatal sonography. These most commonly include ventriculomegaly, abnormalities of the corpus callosum, and abnormalities of the posterior fossa. Fetal MRI is also increasingly performed to evaluate fetuses who have normal brain findings on prenatal sonogram but who are at increased risk for neurodevelopmental abnormalities, such as complicated monochorionic twin pregnancies. This paper will briefly discuss the common clinical conditions imaged by fetal MRI as well as recent advances in fetal MRI research.

A dynamic 4D probabilistic atlas of the developing brain

TL;DR: In this article, the authors describe a 4D probabilistic atlas that allows dynamic generation of prior tissue probability maps for any chosen stage of neonatal brain development between 29 and 44 gestational weeks.

A spatiotemporal atlas of MR intensity, tissue probability and shape of the fetal brain with application to segmentation

TL;DR: Experimental results indicate that quadratic temporal models can correctly capture growth-related changes in the fetal brain anatomy and provide improvement in accuracy of atlas-based tissue segmentation.

Exclusion of fetal ventriculomegaly with a single measurement: the width of the lateral ventricular atrium.

TL;DR: The ventricular atria in 100 healthy fetuses with gestational ages ranging from 14 to 38 menstrual weeks were evaluated and compared with those of 38 fetuses in whom ventriculomegaly had been diagnosed in utero, finding that the normal atrial diameter remained relatively constant throughout the gestational age range observed.

Magnetic resonance imaging of the fetal brain and spine: an increasingly important tool in prenatal diagnosis, part 1.

TL;DR: This 2-part review summarizes some of the latest developments in MR imaging of the fetal brain and spine and its application to prenatal diagnosis and focuses on additional clinical applications of fetal MR imaging, including suspected abnormalities of the corpus callosum, malformations of cortical development, and spine abnormalities.

Registration-based approach for reconstruction of high-resolution in utero fetal MR brain images.

TL;DR: Results indicate that this method promises a unique route to acquiring high-resolution MRI of the fetal brain in vivo allowing comparable quality to that of neonatal MRI.
