Prenatal imaging – role of fetal MRI

Abstract

Background

Congenital abnormalities occur in about 3 in 100 fetuses. Prenatal ultrasound is the standard technique to detect these fetal abnormalities. In Germany, three ultrasound examinations are provided in the first, second, and third trimesters, respectively. Fetal magnetic resonance imaging (MRI) can be used as an adjunct technique to provide further information in cases of congenital abnormalities.

Method

A literature search was performed on PubMed focusing on publications that used fetal MRI as a secondary approach after prenatal ultrasound.

Results

MRI is a safe imaging method that does not harm the fetus when used during pregnancy. Some publications with experts in radiology show a very clear diagnostic advantage with respect to performing MRI on fetuses with brain abnormalities, while other publications with experts in neurosonography do not find the advantage to be that evident. Both techniques are clearly user-dependent.

Conclusion

Fetal MRI can supplement the information obtained by fetal ultrasound and can provide additional information or exclude others. Diagnosis made by an interdisciplinary cooperation based on all available ultrasound and MRI findings is the key to optimal imaging and advice for expectant parents.

Key Points

• Fetal MRI poses no risk for the fetus.

• MRI aids prenatal ultrasound in the evaluation of prenatal findings.
