Fetal magnetic resonance imaging: indications, study protocols and safety

The aim of this paper is to outline the real indications for fetal magnetic resonance imaging (FMRI) based on the current clinical and scientific evidence and to determine where it fits into prenatal diagnostic protocols. We also consider the most commonly used FMRI diagnostic protocols and take stock of the safety aspects of this examination. This paper is the result of the work of the Fetal Magnetic Resonance (FMR) Study Group of the Italian Society of Medical Radiology (SIRM) in cooperation with the Study Group of the Italian Society of Ultrasound in Obstetrics and Gynaecology (SIEOG). It has been reviewed and approved by the Italian Association of Neuroradiology (AINR). As FMRI is undergoing continuous development, and its indications and role are also likely to change over time, the Fetal Magnetic Resonance Study Group is in agreement with the other scientific bodies involved in the drafting of this document to propose subsequent modifications to it when new clinical and scientific evidence suggest the need
