Longitudinal 4D Flow MRI‐Derived Wall Shear Stress in Patients With an Abdominal Aortic Aneurysm

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background 4D flow MRI‐derived parameters such as wall shear stress (WSS) may improve abdominal aortic aneurysm (AAA) progression prediction. Validation of this biomarker is needed, but longitudinal data are lacking. Purpose Investigate longitudinal WSS changes and associations with AAA morphology. Study Type Prospective.

Diagnostic dilemma of cystic biliary atresia: A series of two cases and brief review of the diagnostic modalities

open access: yesJPGN Reports, EarlyView.
Abstract Cystic biliary atresia (CBA) is a rare variant of biliary atresia that closely resembles choledochal cyst (CC), complicating diagnosis and potentially delaying critical surgical intervention. We report two cases of CBA that were difficult to diagnose.

Pre‐ and Post‐Interventional Hemodynamic Characterization of the Femoropopliteal Artery Using Vector Flow Imaging in Peripheral Arterial Occlusive Disease

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives The femoropopliteal (FP) artery is the most frequently revascularized segment in peripheral artery disease (PAD), followed by the iliac segment. Wall shear stress (WSS) is a key local factor implicated in both atherosclerotic plaque formation and restenosis after angioplasty.

Broadband Mode Converter With Customizable Modal Ratio Leveraging Subwavelength Engineering for Advanced Multimode Silicon Photonics

open access: yesLaser &Photonics Reviews, EarlyView.
This work introduces a customizable mode converter for multimode silicon photonics, enabling precise control over the conversion ratio between optical modes. The device operates across a broad wavelength range (1350–1700 nm) with 15 distinct conversion levels.

Observation of Linear and Nonlinear Light Trapping on Topological Dislocations

open access: yesLaser &Photonics Reviews, EarlyView.
Topological dislocations are global lattice defects found in various systems ranging from crystals to photonic lattices. This work reports the first observation at optical frequencies of linear modes with tunable localization bound to edge dislocations and their nonlinear counterparts ‐ dislocation solitons. These results reveal an intriguing interplay
