T2‐Weighted T1 Mapping and Automated Segmentation of CSF: Assessment of Solute Gradients in the Healthy Brain

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Cerebrospinal fluid (CSF) serves as a medium for nutrient delivery and waste clearance. The T1 relaxation rate, R1, can be used to measure the concentration of intrinsic solutes and extrinsic contrast agents. Purpose To implement a method for R1 mapping and segmentation of CSF and to use this method to explore how R1 of CSF relates ...

Towards Clinical Translation of Intravoxel Incoherent Motion MRI: Acquisition and Analysis Consensus Recommendations

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Intravoxel incoherent motion (IVIM) MRI allows for simultaneous assessment of tissue microcirculation (perfusion) and diffusion of water. In single‐center studies, IVIM has shown great potential for diagnosis, treatment outcome prediction, and treatment monitoring for many different diseases and organs.

Impact of 1024‐Matrix Size on Perforating Artery Visualisation in Cerebral Computed Tomography Angiography Using a 64‐Slice CT Scanner

Journal of Medical Radiation Sciences, EarlyView.
This study investigated whether using a larger image matrix (1024 × 1024 pixels instead of 512 × 512) improves the visibility of tiny brain arteries on CT scans performed with standard 64‐slice scanners. While physical image quality measurements remained unchanged, the larger matrix provided finer digital sampling of blood vessel structures, resulting ...

Deresuscitation Informed by Ultrasound in Patients with Septic Shock Trial

Journal of Ultrasound in Medicine, EarlyView.
Objectives The venous excess ultrasound (VExUS) can be used at the point‐of‐care to identify venous overload and end‐organ congestion in an effort to individually tailor resuscitation and deresuscitation in patients with septic shock. Methods We conducted a pilot randomized controlled feasibility trial of VExUS‐guided fluid management in adult patients

A Novel Slit Lamp‐Based System for 3D Ultrasound of the Eye

Journal of Ultrasound in Medicine, EarlyView.
Objectives This study aims to develop and evaluate a novel slit‐lamp‐based system to acquire 3‐dimensional (3D) ultrasound volumes using conventional ultrasound probes. Methods A slit‐lamp adapter was 3D printed and connected with a linear actuator and graphical user interface (GUI) system to control movement and create volumes of 2‐dimensional scans ...
