Area of Science:

  • Medical Imaging
  • Fetal Cardiology
  • Diagnostic Ultrasound

Background:

  • Congenital heart defects (CHDs) affect approximately 10% of newborns, posing a significant diagnostic challenge despite advances in prenatal screening for fetal malformations.
  • Current antenatal diagnosis of CHDs relies heavily on operator expertise, limiting consistent detection rates.
  • Existing ultrasound techniques face challenges in clearly visualizing complex fetal heart structures.

Purpose of the Study:

  • To explore the utility of computer-assisted ultrasound imaging techniques for improving the prenatal detection of congenital heart defects.
  • To evaluate novel imaging procedures that provide internal fetal views for enhanced visualization of cardiac anomalies.
  • To assess the feasibility of routine cardiac volume sampling for CHD screening.

Main Methods:

  • Utilizing advanced computer-assisted ultrasound imaging with volume rendering and post-acquisition slice selection.
  • Acquiring and storing two-dimensional (2D) cardiac volumes from standard long axis and apical views for detailed examination.
  • Developing internal fetal views comparable to those seen in open-heart surgery.

Main Results:

  • New imaging procedures enable internal fetal views, offering visualization similar to open-heart surgery.
  • Computer-assisted techniques facilitate easier recognition of fetal heart anomalies compared to conventional methods.
  • Challenges such as fetal movement, maternal obesity, and fetal spine position can impede examination quality.

Conclusions:

  • Computer-assisted ultrasound imaging holds significant promise for improving the antenatal diagnosis of congenital heart defects.
  • Advancements in image acquisition speed and data storage are crucial for enabling real-time 3D imaging for CHD screening.
  • Routine implementation of cardiac volume sampling could enhance early detection rates for fetal heart malformations.
