Dynamic pseudo‐continuous arterial spin labeling angiography using a 3D‐radial multi‐spoke spoiled gradient‐recalled sequence

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 724-739, February 2026.
Abstract Purpose Accurate identification of arterial feeders and draining veins is critical for treatment decision‐making in patients with intracranial high‐flow vascular lesions. Currently available MRI sequences lack the temporal and spatial resolution needed for this task.

Few‐shot learning for highly accelerated 3D time‐of‐flight MRA reconstruction

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 770-786, February 2026.
Abstract Purpose To develop a deep learning‐based reconstruction method for highly accelerated 3D time‐of‐flight MRA (TOF‐MRA) that achieves high‐quality reconstruction with robust generalization using extremely limited acquired raw data, addressing the challenge of time‐consuming acquisition of high‐resolution, whole‐head angiograms.

Magnetic Milli‐Spinner for Robotic Endovascular Surgery

Advanced Materials, Volume 38, Issue 4, 16 January 2026.
The magnetic milli‐spinner, with its unique structural design, achieves rapid and stable navigation through complex vasculature at speeds up to 23 cm·s−1. It further enables multifunctional treatment, including localized suction and shear for efficient clot removal, targeted drug delivery, and in situ embolization for aneurysm therapy, establishing it ...
