Summary
This study introduces a novel 3D ultrasound method for accurate fetal perfusion measurement, improving upon older techniques. The new approach offers a reliable way to assess fetal blood flow, aiding in the understanding of fetal development.
Area of Science:
- Medical Imaging
- Fetal Physiology
- Ultrasound Technology
Background:
- Previous 2D imaging methods for fetal global perfusion lacked reliability.
- Current methods, like Radioimmunoassay (RI) measurements, do not accurately reflect fetal blood flow.
- There is a need for improved techniques to assess fetal perfusion.
Purpose of the Study:
- To present a novel three-dimensional (3D) approach for calculating fetal global perfusion.
- To overcome the limitations of existing 2D and RI measurement techniques.
- To provide a more accurate and reliable method for fetal perfusion evaluation.
Main Methods:
- A 3D color Doppler sonographic record of the umbilical cord was obtained in 124 singleton pregnancies.
- Dedicated software (PixelFlux) calculated the spatial angle of the umbilical vein.
- Fetal perfusion was determined by multiplying the cross-sectional area by spatial angle-corrected velocity.
Main Results:
- Phantom flow measurements showed a high correlation (r=0.987-0.991) between actual flow and PixelFlux measurements.
- Interobserver correlation was exceptionally high (r=0.997).
- Fetal volume flow correlated significantly with gestational age and weight, influenced by spatial angle.
Conclusions:
- Spatial angle-corrected global fetal perfusion measurement is an improvement over existing methods.
- The PixelFlux technique is feasible, simple, and fast for clinical use.
- This method can aid in exploring the relationship between fetal perfusion and developmental disturbances.
