Performance of Free‐Running Cardiac and Respiratory Motion‐Resolved Whole‐Heart 5D MRI in Congenital Heart Disease Patients Using a Gadolinium Enhanced Fast‐Interrupted Steady‐State Sequence

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The performance of 5D imaging in CHD has been previously demonstrated using ferumoxytol rather than gadolinium. Purpose To evaluate the performance of gadolinium enhanced 5D MRI relative to 2D and 3D MRI in CHD patients. Study Type Retrospective.

Acute Effects of Smoking and Vaping on Markers of Vascular Function via Quantitative MRI

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background E‐cigarettes contribute to endothelial dysfunction, a known cause of systemic atherosclerotic disease that cannot be adequately characterized by a single physiological parameter measured at a single vascular bed. Purpose/Hypothesis Quantify and compare acute effects of smoking or vaping with tobacco cigarettes (t‐cigs), nicotinized ...

Approaches to Computed Tomography Education for Radiography Students

open access: yesJournal of Medical Radiation Sciences, EarlyView.
The aim of this narrative review was to explore the current published literature relating to CT teaching methods and assessment of diagnostic radiography students during university training. Existing CT education evaluations focus on student satisfaction and usability of tools, with post‐lesson knowledge gains reported. Future work should shift towards

Ultra‐High Frequency Ultrasound Imaging and Quantification of Microvascular Flow in Xenograft Renal Cell Carcinoma in an Avian Chorioallantoic Membrane Model

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Patient‐derived xenograft (PDX) tumor models initiated in avian chorioallantoic membranes (CAM) are under investigation to evaluate the effectiveness of therapeutic options with the objective of personalizing treatments. CAM PDXs paired with ultra‐high frequency ultrasound (UHFUS) imaging could potentially constitute prospective high throughput assays ...

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

open access: yesLaser &Photonics Reviews, EarlyView.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Integrated Photonic Modulator Circuit With Programmable Intensity and Phase Modulation Response

open access: yesLaser &Photonics Reviews, EarlyView.
A platform‐agnostic programmable modulation circuit is introduced to enable tunable and universal optimization of integrated photonic modulators. By flexibly controlling carrier amplitude and phase, the approach adapts to diverse device characteristics without structural redesign.
