Retention of Gadolinium in Cerebrospinal Fluid and Decreased Renal Function: A Case Report
A gadolinium-based contrast is the preferred agent when differentiating acute neurological diseases. Since the renal route is the main pathway for excretion of gadolinium chelates, prolonged extracellular distribution of gadolinium has previously been ...

Introduction The term ‘subarachnoid haemorrhage’ (SAH) stands for bleeding into the subarachnoid space, regardless of its source. It may be of primary character when the source of bleeding is situated within the subarachnoid space.

Objectives This study aimed to compare changes in ultrasonic Doppler parameters, particularly the peak ratio (PR) of the ophthalmic artery (OA) and optic nerve sheath diameter (ONSD), in pregnancies complicated by fetal growth restriction (FGR). Furthermore, it sought to evaluate differences in these parameters across various subgroups and analyze the ...

Decreased aneurysmal subarachnoid hemorrhage incidence rate in elderly population than in middle aged population: a retrospective analysis of 8,144 cases in Mainland China [PDF]
Purpose: Rupture of an intracranial aneurysm is the most common cause of subarachnoid haemorrhage (SAH), which is a life-threatening acute cerebrovascular event that typically affects working-age people. This study aims to investigate the aneurysmal SAH incidence rate in elderly population than in middle aged population in China. Materials and methods:

Visualization of Cerebrospinal Fluid Outflow and Egress along the Nerve Roots of the Lumbar Spine
Intrinsic cerebrospinal fluid (CSF) dynamics in the brain have been extensively studied, particularly the egress sites of tagged intrinsic CSF in the meninges. Although spinal CSF recirculates within the central nervous system (CNS), we hypothesized that

Genetic Risk Factors in Normal Pressure Hydrocephalus: What We Know and What Is Next
Abstract Knowledge of the genetic factors in normal pressure hydrocephalus (NPH) is rapidly evolving, with significant advances in recent years. We conducted a systematic review examining genetic contributions to NPH risk. Ovid Embase, Ovid Medline, Web of Science, and Cochrane Central were searched from inception through October 14, 2024, for human ...

Material modeling of the head’s subarachnoid space
AbstractThe goal of this study is to investigate the mechanotransduction of an external load to the brain and the causation of concussion and Traumatic Brain Injury (TBI). However, as one step toward this goal, in this paper, the investigation of the material model selection and material properties of the subarachnoid space (SAS) are presented.

ABSTRACT Quantitative understanding of drug penetration and exposure in the human central nervous system (CNS) and brain tumors is essential for the rational development of new drugs and optimal use of existing drugs for brain cancer. To address this need, we developed and validated a novel 9‐compartment permeability‐limited CNS (9‐CNS) physiologically

Admissibly Represented Spaces and Qcb-Spaces [PDF]
A basic concept of Type Two Theory of Effectivity (TTE) is the notion of an admissibly represented space. Admissibly represented spaces are closely related to qcb-spaces. The latter form a well-behaved subclass of topological spaces. We give a survey of basic facts about Type Two Theory of Effectivity, admissibly represented spaces, qcb-spaces and ...
