This white paper presents a structured imaging approach for diagnosing placenta accreta spectrum (PAS), a condition where the placenta abnormally attaches to the uterine wall, potentially leading to severe complications. Early detection is critical for surgical planning and maternal safety.
The report highlights a combination of 2D, 3D, and Doppler ultrasound techniques in placenta accreta ultrasound. Key sonographic signs include loss of the retroplacental clear zone, myometrial thinning, placental bulging, and the tramline sign, which assesses the interface between the bladder and uterus. These signs are essential markers in placenta accreta spectrum ultrasound.
Samsung’s imaging technologies—CrystalVue™ for high-resolution 3D rendering, MV-Flow™ for visualizing slow-flow microvasculature, and LumiFlow™ for enhanced 3D-like vascular flow—play a vital role in improving diagnostic accuracy. These tools help visualize features such as bridging vessels, subplacental hypervascularity, and irregular vascular patterns, which are commonly associated with PAS.
The paper emphasizes a standardized, multimodal ultrasound approach that increases diagnostic confidence and supports clinical decision-making. By integrating advanced imaging tools with traditional prenatal ultrasound, healthcare providers can more effectively diagnose placenta accreta spectrum and reduce risks during delivery.
