Invent of 3D and 4D ultrasound has made a dramatic improvement in fetal imaging. Various viewing directions and rendering modes help better demonstration of pathologies suspected on 2D US. Multiplanar mode is the key of the 3D US imaging. Software like magicut and TUI help to understand the anatomy better. Volume ultrasound is an excellent tool for diagnosis of facial defects, spinal abnormalities, limb abnormalities, etc. 4D US shows fetal movements and expressions that are basis for the neurodevelopment of the fetus. STIC and VCAD are the tools that have made detection of fetal cardiac anomalies more precise.
