Quantitative Evaluation of Carotid Artery Stenosis by Multi‐VENC 4D Flow MRI: Incorporating Turbulent Kinetic Energy for Clinical Validity

open access: yesJournal of Magnetic Resonance Imaging, Volume 62, Issue 4, Page 1168-1177, October 2025.
ABSTRACT Background Cervical internal carotid artery stenosis (ICS) is a recognized risk factor for ischemic stroke, yet morphological severity alone may not fully reflect hemodynamic alterations. Turbulent kinetic energy (TKE), derived from multi‐velocity‐encoding (multi‐VENC) four‐dimensional (4D) flow MRI, may provide a robust marker for ICS ...

Quantitative susceptibility mapping in the human brain at 7T with phase‐cycled balanced SSFP

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 4, Page 1469-1484, October 2025.
Abstract Purpose To demonstrate the feasibility of QSM and to show the potential of simultaneous T1$$ {T}_1 $$, T2$$ {T}_2 $$, and proton density (PD) mapping in the human brain at 7T based on phase‐cycled balanced SSFP (bSSFP) MRI. Methods An algorithm was developed to estimate off‐resonance frequency in multi‐compartment scenarios by combining ...

Potential of Guidewire‐Clot Interaction Forces for Clot Detection in Robotic Mechanical Thrombectomy

open access: yesThe International Journal of Medical Robotics and Computer Assisted Surgery, Volume 21, Issue 5, October 2025.
ABSTRACT Background Interventional neuroradiologists currently miss crucial information when facing an ischaemic stroke case as they cannot localise the thrombus precisely nor determine its mechanical properties, which are both important for the clot extraction procedure.

Morphometric analysis of spina bifida after fetal repair shows new subtypes with associated outcomes

open access: yesUltrasound in Obstetrics &Gynecology, Volume 66, Issue 4, Page 443-452, October 2025.
ABSTRACT Objectives The binary classification of spina bifida lesions as myelomeningocele (with sac) or myeloschisis (without sac) belies a spectrum of morphologies. This study aimed to characterize types of spina bifida lesion and correlate them with preoperative presentation and postoperative outcome.
