Postmortem MRI (MR autopsy) offers valuable insights for fetal malformations, serving as a potential alternative to traditional necropsy. This imaging technique aids in validating obstetric care and assessing risks for future pregnancies.

Area of Science:

  • Medical Imaging
  • Fetal Pathology
  • Obstetrics

Background:

  • Necropsy is the traditional method for examining fetal malformations.
  • Prenatal ultrasound (US) is crucial for diagnosing fetal abnormalities.
  • Accurate diagnosis is vital for obstetric management and genetic counseling.

Purpose of the Study:

  • To evaluate postmortem magnetic resonance imaging (MR autopsy) as a non-invasive alternative to fetal necropsy.
  • To assess the utility of MR autopsy in validating obstetric management.
  • To determine the value of MR autopsy in risk counseling for future pregnancies.

Main Methods:

  • 10 malformed fetuses underwent postmortem MRI within 24 hours of delivery.
  • Prenatal ultrasound (US) was performed for all cases.

  • Complete necropsy served as the gold standard for comparison.

    • Main Results:

    • MR autopsy successfully confirmed all diagnoses that led to pregnancy termination based on US findings.
    • All MRI results were corroborated by necropsy findings.
    • Necropsy provided additional crucial information for risk counseling in two cases, and histology corrected one diagnosis.

    Conclusions:

    • Postmortem MRI provides significant diagnostic information comparable to necropsy.
    • MR autopsy can be a valuable tool for parents declining perinatal necropsy, aiding in obstetric management validation and future pregnancy risk assessment.
    • While MR autopsy is highly informative, necropsy remains the definitive gold standard for fetal examination.
