“…Another concern of fetal imaging with MRI is a potential detrimental effect of the scanning noise. Nevertheless, no evidence of distress of the fetus during scanning [65] or hearing deficits in children scanned prenatally [63] have been observed. Still, several precautions can be taken into consideration to lower the noise level during the scan, which can be achieved by altering scan parameters or using different sequences.…”

The brain is subject to dramatic developmental processes during the prenatal period. Nevertheless, information about the development of functional brain networks during gestation is scarce. Until recently it has not been possible to probe function in the living human fetal brain. Advances in functional MRI have changed the paradigm, making it possible to measure spontaneous activity in the fetal brain and to cross-correlate functional signals to attain information about neural connectional architecture across human gestation. We summarize the earliest MRI studies of fetal neural functional connectivity and highlight unique challenges and limitations inherent in the technique. In addition, we discuss future directions to unlock the potential of fetal brain functional MRI research.

“…Recently, the regional pattern of heat absorption within the mother and fetus was reported using a mathematical model for both 1.5 and 3 Tesla showing that maximum heat deposition was in the mother (Hand et al, 2006). To date, studies have shown no sustained increases in fetal heart rate during MRI and no evidence of hearing impairments in children who had undergone MRI as a fetus (Myers et al, 1998;Vadeyar et al, 2000;Kok et al, 2004). In contrast there are many studies comparing the ability of MRI to detect and assess abnormalities suspected on antenatal ultrasound and all conclude that the two techniques are complimentary ( Fig.…”

Fetal magnetic resonance imaging provides an ideal tool for investigating growth and development of the brain in vivo. Current imaging methods have been hampered by fetal motion but recent advances in image acquisition can produce high signal to noise, high resolution 3-dimensional datasets suitable for objective quantification by state of the art post acquisition computer programs. Continuing development of imaging techniques will allow a unique insight into the developing brain, more specifically process of cell migration, axonal pathway formation, and cortical maturation. Accurate quantification of these developmental processes in the normal fetus will allow us to identify subtle deviations from normal during the second and third trimester of pregnancy either in the compromised fetus or in infants born prematurely.

“…Clinically relevant levels of MRI exposure in pregnant rats in late gestation have failed to reveal any adverse effect on the fetal or neonatal developing brain [40]. In humans, no significant changes in fetal activity or fetal cardiac parameters have been reported in relation to MRI [8,9,41]. Furthermore, to date, no correlation has been established between intrauterine growth restriction and in utero MRI exposure in humans [6,12,42].…”
