Fetal behavior assessed by four-dimensional sonography

Abstract

The Kurjak’s antenatal neurodevelopmental test (KANET) is currently used by many centers in everyday clinical practice as the investigational tool for normal and high-risk fetuses. It has acceptable sensitivity and specificity, adequate positive and negative predictive vales, inter-and intra-observer realiability, and can be easily learned by US specialists with access to 4D US machines. The aim of the KANET is to be widely applied in clinical practice for the selective screening of fetuses with moderate and high neurological risk; hopefully, the early detection of these fetuses would allow at last the diagnosis of severe cases in utero and also an early intervention that could improved the outcome for these neonates.
