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 ...

3D Whole‐Heart Joint T1/T1ρ Mapping and Water‐Fat Imaging on a Clinical 0.55‐T Low‐Field Scanner

NMR in Biomedicine, Volume 39, Issue 2, February 2026.
A 3D joint T1/T1ρ$$ \rho $$ mapping sequence was proposed at 0.55 T. Four interleaved T1 and T1ρ$$ \rho $$ encoded 3D volumes are acquired; images are reconstructed with nonrigid respiratory motion‐correction, low‐rank patch‐based denoising (HD‐PROST) and water‐fat separation; and T1/T1ρ$$ \rho $$ maps are estimated through dictionary matching.

Pregnancy and Delivery Outcomes in Vascular Ehlers–Danlos Syndrome: A Retrospective Multicentre Cohort Study

BJOG: An International Journal of Obstetrics &Gynaecology, Volume 133, Issue 3, Page 463-470, February 2026.
ABSTRACT Objective We aim to increase knowledge on pregnancy and delivery risks in vascular Ehlers–Danlos Syndrome (vEDS). Our outcomes can contribute to establishing future guidelines for pregnancy and delivery management in women with vEDS. Design Retrospective multicentre cohort study.
