Summary
Post-mortem MRI precisely diagnosed fetal hydranencephaly, overcoming limitations of traditional autopsy and ultrasound. This imaging is crucial for accurate diagnosis and assessing risks for future pregnancies.
Area of Science:
- Medical Imaging
- Pathology
- Fetal Abnormalities
Background:
- Classic pathological-anatomical autopsy is standard for determining fetal abnormalities.
- Autopsy limitations, such as autolysis or ventricular dilatation, can hinder diagnosis.
- Prenatal ultrasound may present diagnostic challenges for certain congenital malformations.
Observation:
- This case report details a fetal abnormality where ultrasound suggested alobar holoprosencephaly.
- Post-mortem magnetic resonance imaging (MRI) was performed due to diagnostic limitations.
- Pathological-anatomical autopsy was significantly limited and could not unequivocally determine the malformation type.
Findings:
- Post-mortem MRI precisely identified the congenital malformation as hydranencephaly.
- This contrasts with the initial ultrasound diagnosis, highlighting MRI's superior diagnostic accuracy in complex cases.
- MRI provided a definitive diagnosis where traditional autopsy failed.
Implications:
- Post-mortem MRI serves as a valuable supplementary tool to conventional autopsy.
- Accurate diagnosis of fetal malformations is essential for parental understanding and counseling.
- This imaging modality is vital for determining risks associated with future pregnancies.

01:24Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
