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.

Combined angiography and perfusion using radial imaging and arterial spin labeling with structural contrast

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 787-802, February 2026.
Abstract Purpose To develop a non‐contrast MRI method for the simultaneous acquisition of time‐resolved 3D angiographic, perfusion, and multi‐contrast T1‐weighted structural brain images in a single 6 min acquisition. Methods The proposed combined angiography and perfusion using radial imaging and arterial spin labeling with structural contrast (CAPRIA+

Transcranial Doppler ultrasound validation of BOLD‐fMRI cerebral blood flow relationship

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 939-950, February 2026.
Abstract Purpose A precise understanding of the interplay between cerebral blood flow (CBF) and blood oxygen level‐dependent (BOLD) fMRI signals is essential for advancing cerebrovascular research. Although calibrated BOLD approaches often rely on arterial spin labelling (ASL) to estimate CBF, alternative validation using transcranial Doppler ...
