Fetal MRI : an essential step in interpreting complex ultrasound findings

Abstract

Background: Fetal magnetic resonance imaging (MRI) allows for the interpretation of complex fetal anomalies detected on ultrasound (US). Locally it has been available since 2013 but has remained underused. Method: In this paper we report the US and MRI findings of all cases of fetal MRI that were taken to date locally and how MRI can contribute to the clarification of malformations, management, counseling, evaluation of prognosis and ruling out of other possible malformations. Results: The cases reported were: two cases of hydroureter; gastroschisis; ventriculomegaly; intracranial haemorrhage; splenic cyst; Arnold Chiari II malformation. In all seven cases MRI was able to add to or change the diagnosis. Conclusion: Fetal MRI acts as an adjunct to US in interpreting abnormal fetal development. It is a safe non-invasive method of imaging that allows the clinician to take more informed decisions and better parental counselling.
