WebCavum septum pellucidum (CSP) is one of the most important physiologic structures that should be detected in Ultrasound (US) scanning for the normal development of the fetal central nervous system. However, manual measurement of CSP is still a difficult and time-consuming task due to the high noise of US images, even for experienced sonographers. WebThe CSP reaches its adult configuration by 17 weeks’ gestation 5,6. The CSP can be documented in virtually 100% of cases between 18 and 37 weeks’ gestation. The detection rate declines to 79% between 38 and 41 weeks’ gestation. Hence, failure to detect the CSP prior to 18 weeks or after 37 weeks should be considered a normal finding 7,8.
