In this Expert Insights session from ISUOG 2024, Prof. Daniele Di Mascio discusses the latest innovations in 2nd trimester ultrasound for evaluating the central nervous system (CNS) and fetal heart. The session focuses on the mid trimester anatomy scan, a crucial step in detecting congenital anomalies before birth.
For fetal brain ultrasound within CNS evaluation, Prof. Di Mascio demonstrates advanced neurosonography techniques such as 3D/4D imaging and automated 5D CNS tools, which streamline the acquisition of standard brain planes. These approaches enhance visualization of key structures including the corpus callosum, ventricles, and posterior fossa, enabling earlier and more reliable fetal anomaly detection. He underlines the importance of adhering to international CNS ultrasound guidelines for consistent and accurate diagnoses.
It also highlights new software and technologies that are useful for examining the fetal face, spine, heart, and brain, and argues that these advancements could shape the future of fetal medicine and enhance patient bonding.
For fetal heart ultrasound, the discussion covers essential screening views — including the four-chamber view, outflow tracts, and three-vessel trachea view — along with automation features that help secure complete assessments even with challenging fetal positions. Guidelines from the American Institute of Ultrasound in Medicine and Israeli protocols are referenced for comprehensive cardiac evaluation.
Case examples illustrate how combining advanced imaging tools with standardized protocols improves diagnostic accuracy, supports clinical decision-making, and facilitates clear communication with parents.
By implementing these expert recommendations, clinicians can enhance the quality and efficiency of mid trimester prenatal assessments, ensuring thorough CNS and cardiac evaluation.
