How to read a fetal magnetic resonance image 101

Area of Science:

• Radiology
• Medical Imaging
• Obstetrics

Background:

• Accurate antenatal diagnosis is crucial for effective pregnancy management and optimal perinatal outcomes.
• Prenatal imaging, particularly fetal MRI, significantly enhances the information available for prognostication.
• Interpreting fetal MRI can be challenging for trainees due to the complexity of image acquisition, interpretation, and reporting.

Purpose of the Study:

• To provide radiology trainees with a structured approach to interpreting fetal MRI.
• To review the added value of prenatal MRI in assessing fetal wellbeing.
• To offer guidance on MRI protocols, techniques, and normal maternal and fetal anatomy.

Main Methods:

• Review of existing literature and established protocols for fetal MRI.
• Discussion of image acquisition and interpretation techniques specific to fetal MRI.
• Presentation of normal fetal and maternal anatomy on MRI.

Main Results:

• Fetal MRI provides critical prognostic information, improving diagnostic accuracy.
• Established MRI protocols and techniques facilitate comprehensive fetal assessment.
• Understanding normal anatomy is key to identifying abnormalities.

Conclusions:

• Fetal MRI is an invaluable tool for antenatal diagnosis and management.
• A systematic approach and knowledge of normal anatomy are essential for accurate interpretation.
• Structured reporting templates aid radiologists in delivering consistent and thorough reports.
