Prenatal MRI of the brain. Retrospective study apropos of 34 tests
We performed 34 antenatal MRI, in utero in 29 foetuses with cerebral malformations depicted by US. For five patients, a second antenatal MRI was performed because of a technical failure or of diagnosis doubt. We considered that MRI is a valuable imaging method. We have observed 2 false negatives (myelomeningocele, gyration abnormality) on MR study (n = 34). MRI is more contributive that US for the etiological diagnosis of ventricular enlargement: 83% versus 46%. MRI depicted corpus callosum agenesis misdiagnosed in 5 patients by US. MR results modified the therapeutic procedure in 37% of our patients. We think that the optimal term to perform MRI study is after 28 weeks gestational age because of the size of the fetus and for the timing of cerebral development. Ventricular dilatation (criteria: occipital horn size more that one centimeter at 25 weeks of term) is the main indication of MR study.
