Summary
Three-dimensional (3D) sonography enhances visualization of placental abnormalities in utero, offering improved detail over traditional two-dimensional (2D) methods for conditions like chorioangioma and placental cysts.
Area of Science:
- Medical Imaging
- Obstetrics and Gynecology
- Fetal Medicine
Background:
- Placental abnormalities require accurate in utero diagnosis.
- Two-dimensional (2D) sonography has limitations in visualizing complex structures.
- Three-dimensional (3D) sonography offers advanced visualization capabilities.
Purpose of the Study:
- To describe the three-dimensional (3D) sonographic features of various placental abnormalities.
- To evaluate the utility of 3D sonography in visualizing placental masses in utero.
Main Methods:
- Six cases of placental abnormalities (chorioangioma, subchorionic hematoma, placental cysts, subplacental fibromas) were studied.
- Transabdominal 3D sonography was employed between 22 and 34 weeks of gestation.
- Comparison with 2D sonography and color Doppler ultrasound was performed.
Main Results:
- 3D sonography provided superior visualization of structural continuity and curvature compared to 2D.
- Specific features of chorioangioma, placental cysts, and subplacental fibromas were clearly depicted.
- Color Doppler identified abundant blood flow only in the chorioangioma case.
Conclusions:
- 3D sonography effectively visualizes placental abnormalities in utero.
- It serves as a valuable supplement to 2D sonography and color Doppler.
- 3D ultrasound offers a novel approach for identifying placental masses.
