Imaging review of cerebrospinal fluid leaks
Indian Journal of Radiology and Imaging, 2017 Cerebrospinal fluid (CSF) leak occurs due to a defect in the dura and skull base. Trauma remains the most common cause of CSF leak; however, a significant number of cases are iatrogenic, and result from a complication of functional endoscopic sinus ...

Case Report: An Intracranial Complication of COVID-19 Nasopharyngeal Swab
Clinical Practice and Cases in Emergency Medicine, 2021 Introduction: Cerebrospinal fluid (CSF) leaks are often the result of trauma or recent surgical procedures; however, a subset can develop from non-traumatic etiologies.

A Two‐Stage Plasma Biomarker Algorithm Reduces Amyloid PET Use and the p‐Tau217 Gray Zone
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Plasma p‐Tau217 leaves 30%–50% of patients in an indeterminate “gray zone” often requiring Aβ‐PET. We developed GRAD (Gatekeeper‐Reflex for Alzheimer's Disease), a two‐stage Aβ‐positivity prediction model to improve classification while reserving Aβ‐PET for residual uncertainty.

Advanced Healthcare Materials, EarlyView.Mineralization alone does not establish a mature bone organoid. This Review integrates biological foundations, materials design, adaptive remodeling, and translational validation through the development‐to‐remodeling continuum (DRC). By separating biological functions from the evidence supporting them, the framework exposes critical gaps in current ...

CSF rhinorrhea: non-contrast CT, contrast-enhanced CT cisternography or combined?
The Egyptian Journal of Radiology and Nuclear Medicine, 2022 Background Radiologic diagnosis of CSF leaks is challenging. We evaluated the diagnostic value of non-contrast CT and contrast-enhanced CT cisternography in identifying the presence of CSF rhinorrhea and site of leak as well as comparing them to surgical
