Contemporary Modalities to Image the Fetal Brain

Area of Science:

• Medical Imaging
• Neuroscience
• Prenatal Diagnosis

Background:

• Fetal brain ultrasound is the primary method for screening intracranial anatomy.
• Advanced ultrasound techniques like 3D imaging aid in understanding fetal neurodevelopment.
• Neurosonography is utilized for suspected abnormalities or high-risk cases.

Purpose of the Study:

• To highlight the role of fetal brain ultrasound in screening and diagnosis.
• To discuss the complementary nature of neurosonography and fetal MRI.
• To emphasize the benefits of advanced imaging modalities in assessing fetal neurodevelopment.

Main Methods:

• Utilizing standard and 3D fetal brain ultrasound.
• Employing neurosonography with complementary imaging planes (axial, coronal, sagittal).
• Considering fetal brain magnetic resonance imaging (MRI) as an adjunctive tool.

Main Results:

• Ultrasound provides essential screening of fetal intracranial anatomy.
• Neurosonography offers detailed views from transabdominal and transvaginal approaches.
• Fetal MRI demonstrates higher sensitivity and provides advanced insights into brain metabolism, microstructure, and connectivity.

Conclusions:

• Fetal brain ultrasound is a crucial screening modality.
• Neurosonography and fetal MRI serve as valuable tools for detailed fetal brain assessment.
• Advanced imaging techniques improve the understanding of fetal neurodevelopment and potential brain injuries.
