Prenatal magnetic resonance (MR) imaging provides additional diagnostic information for fetal thoracic abnormalities compared to ultrasonography (US). This advanced imaging technique can alter patient care and counseling in a significant number of cases.

Area of Science:

  • Medical Imaging
  • Fetal Medicine
  • Radiology

Background:

  • Prenatal diagnosis of fetal thoracic abnormalities is crucial for planning management.
  • Ultrasonography (US) is the primary imaging modality, but its limitations may necessitate further investigation.

Purpose of the Study:

  • To describe the appearance of fetal thoracic abnormalities using prenatal magnetic resonance (MR) imaging.
  • To evaluate whether MR imaging offers supplementary information beyond US findings.

Main Methods:

  • Retrospective review of US and MR imaging data from 74 fetuses with thoracic abnormalities.
  • Comparison of imaging findings to assess changes in patient counseling and care.
  • Analysis of lung parenchyma, lesions, vascularity, airways, esophagus, and diaphragm on MR images.

Main Results:

  • MR imaging provided additional information in 38% of fetuses, influencing care in 8%.
  • Specific findings included variations in lung signal intensity and visualization of CCAMs/sequestrations.
  • Diaphragm visualization was common, but airway and esophageal findings required careful interpretation.

Conclusions:

  • Prenatal MR imaging is a valuable tool for evaluating fetal thoracic abnormalities.
  • It complements US by providing additional details that can impact clinical decision-making.
