Fetal MR imaging is an increasingly available technique used to evaluate the fetal brain and spine. This is made possible by recent advances in technology, such as rapid pulse sequences, parallel imaging, and advances in coil design. This provides a unique opportunity to evaluate processes that cannot be approached by any other current imaging technique, and it affords a unique opportunity for studying in vivo brain development and early diagnosis of congenital abnormalities inadequately visualized or undetectable by prenatal sonography. 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. The first part discussed the utility, safety, and technical aspects of fetal MR imaging; the appearance of normal fetal brain development; and the role of fetal MR imaging in the evaluation of fetal ventriculomegaly. In this second part, we focus on additional clinical applications of fetal MR imaging, including suspected abnormalities of the corpus callosum, malformations of cortical development, and spine abnormalities. |
