Fetal Magnetic Resonance Imaging of Congenital Renal Anomalies: A Pictorial Review

This is the authors' abstract. We don't add key points for this paper.

Congenital renal anomalies comprise a vast spectrum of pathologies and are often associated with oligohydramnios, which can make prenatal ultrasonography (US) evaluation difficult. However, fetal magnetic resonance imaging (MRI) is less affected by the diminished amniotic fluid and can provide superior image quality. Understanding of fetal renal anomalies and associated malformations is essential for patient counseling and appropriate pregnancy, delivery, and neonatal management. MRI is a well-established and effective diagnostic tool complementing US due to its superior tissue contrast, large field of view, enhanced anatomic evaluation, and more detailed rendering of renal malformations when US findings are equivocal or inconclusive, especially when oligohydramnios is present.
