Fetal Magnetic Resonance Imaging of the Central Nervous System

Abstract

Fetal magnetic resonance imaging (MRI) represents a noninvasive imaging technique that allows a detailed visualization of the fetus in utero as well as of the maternal structures, including the birth canal. Until recently, the long acquisition times of conventional MRI sequences prohibited detailed studies of the fetal anatomy due to motion artifacts. However, fetal motion artifacts can be successfully suppressed or minimized by shortening the acquisition time (Fig. 27.1). The ongoing development of ultrafast MRI scanners and sequences, currently with acquisition times shorter than 400 ms per slice, allows to “picture-freeze” the fetus during motion. A variety of ultrafast sequences are available, including echoplanar, half-Fourier single-shot fast spin-echo and fast gradient-echo sequences. Similar to standard spin-echo sequences, T1- and T2-weighted images can be obtained.
