Imaging in fetal genital anomalies

Area of Science:

• Medical Imaging
• Fetal Medicine
• Congenital Anomalies

Background:

• Genital anomalies are increasingly recognized since the 2005 Chicago Consensus.
• Postnatal diagnosis has advanced, but prenatal diagnosis remains underdeveloped with low rates.
• Limited protocols and fragmented literature hinder prenatal evaluation of fetal genitalia.

Purpose of the Study:

• To review the current status of prenatal imaging for fetal genital anomalies.
• To examine indications, methodologies, and diagnostic challenges.
• To identify areas for improvement in prenatal diagnosis.

Main Methods:

• Review of current literature and imaging techniques for fetal genitalia evaluation.
• Discussion of indications for fetal sex evaluation (medical and non-medical).
• Analysis of imaging modalities including 2D ultrasound, 3D ultrasound, MRI, and Color Doppler.

Main Results:

• Prenatal diagnosis lacks standardized protocols and guidelines for technical aspects.
• Fetal sex determination methods vary by gestation (early vs. late).
• Commonly diagnosed conditions include ambiguous genitalia, hypospadias, and clitoromegaly.

Conclusions:

• Standardized protocols and clinical guidelines are crucial for advancing prenatal diagnosis of genital anomalies.
• Higher-quality studies are needed to improve diagnostic rates and patient outcomes.
• Addressing ethical and medical issues related to fetal sex disclosure is important.
