Ultrasound and magnetic resonance imaging of fetal gastrointestinal tract disorders

Area of Science:

• Medical Imaging
• Fetal Medicine
• Gastroenterology

Background:

• Congenital anomalies of the fetal digestive tract are significant causes of neonatal morbidity.
• Accurate prenatal diagnosis is crucial for planning management and improving outcomes.
• Ultrasound is the primary imaging modality, but limitations exist in visualizing complex structures.

Purpose of the Study:

• To detail prenatal imaging findings of major fetal digestive tract anomalies using ultrasound and magnetic resonance imaging (MRI).
• To compare the diagnostic capabilities of ultrasound and MRI for these conditions.
• To evaluate the added value of MRI in diagnosing fetal gastrointestinal abnormalities.

Main Methods:

• Review of prenatal imaging studies including ultrasound and MRI.
• Correlation of imaging findings with postnatal diagnoses where available.
• Analysis of specific congenital anomalies such as intestinal atresia, malrotation, and gastroschisis.

Main Results:

• Ultrasound demonstrates characteristic findings for many digestive tract anomalies.
• MRI provides superior soft-tissue contrast and multiplanar visualization, especially for complex cases.
• MRI is particularly useful for evaluating the extent of anomalies and associated complications.

Conclusions:

• Both ultrasound and MRI are valuable for diagnosing fetal digestive tract anomalies.
• MRI serves as a crucial complementary tool when ultrasound findings are indeterminate or complex.
• Accurate prenatal assessment impacts surgical planning and neonatal care for affected infants.
