Summary
Acquiring Spatiotemporal Image Correlation (STIC) fetal heart data can be unsuccessful due to fetal movement artifacts and maternal factors. Optimizing STIC examinations improves antenatal diagnosis of congenital heart disease.
Area of Science:
- Medical Imaging
- Fetal Cardiology
- Obstetric Ultrasound
Background:
- Spatiotemporal Image Correlation (STIC) is crucial for fetal heart imaging.
- High-quality STIC data are essential for antenatal diagnosis of congenital heart disease.
- Understanding factors affecting STIC acquisition is key to improving diagnostic accuracy.
Purpose of the Study:
- To identify risk factors for unsuccessful STIC volume data acquisition.
- To describe a more accurate and efficient STIC examination protocol.
Main Methods:
- A cross-sectional study of 1124 women with fetuses.
- Logistic regression analysis to assess risk factors for unsuccessful STIC acquisition.
- Evaluated variables included maternal BMI, fetal factors, and imaging techniques.
Main Results:
- 18.6% of STIC acquisitions were unsuccessful.
- Independent risk factors for unsuccessful acquisition identified: shadowing artifacts from fetal movement (SAU), maternal BMI ≥ 28 kg/m², not using volume rendering images in 4D-US, estimated fetal weight ≥ 1300 g, and anterior placenta.
- Sonographer proficiency was not a significant factor.
Conclusions:
- Avoiding SAU is critical for successful STIC evaluations.
- Volume rendering images in 4D-US show promise for improving STIC data acquisition.
- Improved STIC techniques enhance antenatal diagnosis of congenital heart disease.
