Abstract

The revolution of ultrasonography in obstetrics has enabled us to assess the neurological development of the fetus in utero. The KANET test has proven to be a useful tool in identifying neurological anomalies and might have the potential to early on diagnose pathologies that nowadays can be diagnosed only postpartum. Studies have shown a strong correlation between antepartum evaluation using four-dimensional ultrasonography for the assessment of the fetal behavior and postpartum neurodevelopment. Studying twin pregnancies can offer us even more insight into fetal development, as they are considered high-risk pregnancies with a higher incidence of lower-weight newborns predisposed to neurological disorders such as cerebral palsy. As neurological disorders are frequently identified in high-risk pregnancies, we reviewed the latest studies on twin pregnancies. We also studied KANET integration in a routine fetal assessment and observed its role in reducing the complications and even in treating neurological disorders prenatally. Along with our personal experience in applying the KANET test in the evaluation of twin pregnancies with a 2-year postnatal follow-up, we hope that a better understanding of fetal neurodevelopment should be reached.
