Researchers from multiple institutions in North America have developed a fully automated, deep-learning (DL), artificial-intelligence clinical tool that can measure the volume of cerebral ventricles ...

Placement of an external ventricular drain (EVD) allows cerebrospinal fluid (CSF) to drain from the ventricles to an external collecting system. The main advantage of an EVD over a device that ...

Enlarged cerebral ventricles are found in 80% of individuals with schizophrenia, yet the mechanisms that lead to ventricular enlargement are mostly unknown. Scientists at St. Jude Children’s Research ...
