Abstract

Since the first report of MRI in pregnancy in 1983 [1], the technique used has considerably evolved. Nowadays, fetal MRI should be performed on a high-field unit (1.5 T) with a phased-array surface coil to achieve optimal imaging quality. The problem of fetal motion has been significantly diminished by the development of ultrafast imaging techniques and a consequent decrease in acquisition time. However, the problem has not been entirely solved and even if many sequences are much faster than they used to be, T1-weighted sequences still require a long time and motion artefacts are therefore still worrying. Fetal sedation is not universally used. In our institution, we continue using a sedation by maternal oral administration of flunitrazepam (1 mg) 30 min before the beginning of the examination.
