Colourings of Uniform Group Divisible Designs and Maximum Packings

open access: yesJournal of Combinatorial Designs, Volume 34, Issue 9, Page 437-456, September 2026.
ABSTRACT A weak c‐colouring of a design is an assignment of colours to its points from a set of c available colours, such that there are no monochromatic blocks. A colouring of a design is block‐equitable, if for each block, the number of points coloured with any available pair of colours differ by at most one.

A Magnetic Resonance Fingerprinting Approach for Simultaneous T1‐ and PRFS‐Based 3D MR‐Thermometry

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 3, Page 1274-1282, September 2026.
ABSTRACT Purpose To evaluate a three dimensional dual echo magnetic resonance fingerprinting sequence for simultaneous proton resonance frequency shift (PRFS) and T1 thermometry during microwave ablation with T1 improving robustness near gas bubble induced susceptibility changes while PRFS provides high precision elsewhere.

Fast and Robust Diffusion Posterior Sampling for MR Image Reconstruction Using the Preconditioned Unadjusted Langevin Algorithm

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 3, Page 1323-1332, September 2026.
ABSTRACT Purpose The Unadjusted Langevin Algorithm (ULA) in combination with diffusion models can generate high quality MRI reconstructions with uncertainty estimation from highly undersampled k‐space data. However, sampling methods such as diffusion posterior sampling (DPS) or likelihood annealing suffer from long reconstruction times and the need for

Single‐Shot 2D Radial Echo Planar Imaging for Functional MRI

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 3, Page 1245-1260, September 2026.
ABSTRACT Purpose To develop a novel single‐shot radial echo planar imaging (ss‐rEPI) technique for rapid, distortion‐free brain imaging in functional MRI experiments. Methods Radial multi‐gradient echo (radial mGRE) data were acquired on a 3T clinical scanner using a 2D ss‐rEPI readout with small golden‐angle rotations between echoes.

Concurrent Four‐Dimensional Dynamic MRA and Perfusion Imaging Using Dual‐Module Arterial Spin Labeling MRI With Stack‐Of‐Stars Golden‐Angle Radial Acquisition

open access: yesNMR in Biomedicine, Volume 39, Issue 9, September 2026.
A dual‐module ASL technique is proposed to obtain both 4D MRA and cerebral perfusion images within a single scan. Both time‐resolved MRA with high spatiotemporal resolution and perfusion‐weighted images with good contrast were successfully obtained from a single scan using the proposed dual‐module ASL technique, suggesting that it could be a ...
