In recent years, several studies have compared two-dimensional (2D) and three-dimensional (3D) ultrasound (US) in the prenatal diagnosis of congenital heart diseases (CHD). These studies have shown that 3D and four-dimensional (4D) ultrasound technologies, especially techniques such as spatiotemporal image correlation (STIC), tend to provide superior accuracy in assessing fetal cardiac anatomy compared to traditional 2D US. In particular, 3D/4D US allows volumetric analysis of cardiac structures and dynamic visualization of the heart in motion, which improves diagnostic accuracy, especially for difficult-to-assess structures such as the pulmonary arteries and venous connections. As a result, the sensitivity and specificity for detecting CHD have been reported to be higher than with 2D US, especially for more complex defects. While 2D US remains a valuable tool, especially for initial screening, the available literature suggests that 3D/4D US could be used, especially by experts in fetal echocardiography, to significantly improve prenatal assessment of CHD.

摘要

In recent years, several studies have compared two-dimensional (2D) and three-dimensional (3D) ultrasound (US) in the prenatal diagnosis of congenital heart diseases (CHD). These studies have shown that 3D and four-dimensional (4D) ultrasound technologies, especially techniques such as spatiotemporal image correlation (STIC), tend to provide superior accuracy in assessing fetal cardiac anatomy compared to traditional 2D US. In particular, 3D/4D US allows volumetric analysis of cardiac structures and dynamic visualization of the heart in motion, which improves diagnostic accuracy, especially for difficult-to-assess structures such as the pulmonary arteries and venous connections. As a result, the sensitivity and specificity for detecting CHD have been reported to be higher than with 2D US, especially for more complex defects. While 2D US remains a valuable tool, especially for initial screening, the available literature suggests that 3D/4D US could be used, especially by experts in fetal echocardiography, to significantly improve prenatal assessment of CHD.
