Computed Tomography Optic Nerve Sheath Diameter-to-Eyeball Transverse Diameter Ratio as a Novel Noninvasive Parameter for Prognostication in Traumatic Brain Injury.

Background Traumatic brain injury (TBI) remains a foremost cause of death and disability globally, with elevated intracranial pressure (ICP) being a crucial factor in patient outcomes. While invasive monitoring is the gold standard for assessing ICP, it carries risks and is not always feasible. This study proposes a novel noninvasive parameter using computed tomography (CT) imaging.

The Role of Phase-Contrast MRI in Diagnosing Cerebrospinal Fluid Flow Abnormalities.

Background Cerebrospinal fluid (CSF) dynamics play a crucial role in maintaining the homeostasis of the central nervous system (CNS). Any disruption in CSF flow can lead to various congenital and acquired conditions, impacting neurological function and overall health. This study aims to analyze the significance of phase-contrast MRI in evaluating abnormalities in CSF flow and its diagnostic utility in various CSF-related disorders.
