Evaluation of Interstitial Fluid Volume and Diffusivity in Patients With Idiopathic Normal Pressure Hydrocephalus Using Spectral Diffusion Analysis

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Changes in interstitial fluid (ISF) dynamics are potential contributors to idiopathic normal pressure hydrocephalus (iNPH). Spectral diffusion analysis provides surrogate markers for ISF volume (Fint) and diffusivity (Dint). Purpose To compare Fint and Dint between patients with iNPH and healthy controls (HCs).

Sonographic Anatomy and Imaging of the Extracranial Component of the Hypoglossal Nerve (CNXII)

open access: yesJournal of Medical Radiation Sciences, EarlyView.
The hypoglossal nerve (HN) provides motor innervation to tongue muscles responsible for tongue movement, speech, mastication, swallowing, respiratory functions and management of oral secretions. The intracranial component of the HN can be demonstrated on magnetic resonance imaging and the extracranial component can be demonstrated with sonographic ...

Point‐Of‐Care Ultrasound in Emergency Departments in Australia/New Zealand: An Emergency Physician's Perspective

open access: yesJournal of Medical Radiation Sciences, Volume 72, Issue 1, Page 3-7, March 2025.
This brief overview of the current state of clinician performed focused ultrasound (Emergency PoCUS) by emergency practitioners in Australia/New Zealand (ANZ) has touched on its history, scope of practice both mandated and context‐dependent, complex embedding in clinical diagnostic reasoning and range of governance issues.

Imaging Characteristics of Persistent Carotid‐Vertebrobasilar Anastomoses Detected by Ultrasound

open access: yesJournal of Ultrasound in Medicine, EarlyView.
In this case series, we aimed to evaluate the ultrasonic characteristics of 35 patients with persistent carotid‐vertebrobasilar anastomoses (PCVBA), a rare variant between the anterior and posterior cerebral circulation. Ultrasound detected seven (30.4%, 7/23) primitive trigeminal arteries (PTA), eight (100%, 8/8) primitive hypoglossal arteries (PHA ...
