ABSTRACT
This pictorial review aimed to describe the assessment of a great variety of congenital heart disease by three-dimensional (3D) ultrasound with spatiotemporal image correlation (STIC) using HDlive and HDlive Flow silhouette rendering modes. These technologies provide fetal heart surface designs as it uses a fixed virtual light source that propagates into the tissues permitting a detailed reconstruction of the heart structures. In this scenario, ultrasound operators can freely select a better light source position to enhance the anatomical details of the fetal heart. HDlive and HDlive Flow silhouette rendering modes improved depth perception and resolution of anatomic cardiac details and blood vessel walls compared to the standard two-dimensional (2D) ultrasound.
