Whole liver phase-based R2 mapping in liver iron overload within a breath-hold. [PDF]

Magn Reson Med
Abstract Purpose Diagnosis and treatment monitoring of iron overload increasingly relies on non‐invasive MRI‐based measurement of liver iron concentration (LIC). Liver R2 mapping is known to correlate well with LIC. However, traditional spin‐echo based R2 mapping methods have drawbacks such as long acquisition times and limited volumetric coverage.

Rapid Free‐Breathing and Automated 2D Shimming of the Lung at 3T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and validate a rapid, fully automated method for shimming of the lung. Methods For field mapping of the lung, a custom 2D RF spoiled gradient echo sequence was used offering sub‐millisecond echo times. At 3T, four echo‐shifted coronal images were acquired with a minimum TE of 0.57 ms and an inter‐echo spacing of 0.1 ms ...

Fast 3D UTE in vivo T1 and T2*$$ {\mathrm{T}}_2^{\ast } $$ mapping of fast relaxing knee tissues at 3 T

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 693-705, February 2026.
Abstract Purpose UTE MR imaging captures quantitative signals in fast‐relaxing tissues, enabling anatomical visualization and quantitative assessment of T1 and T2*$$ {\mathrm{T}}_2^{\ast } $$ relaxation times. However, the clinical application of quantitative UTE MRI is limited by long acquisition times.

Liver fat quantification at 0.55 T enabled by locally low‐rank enforced deep learning reconstruction

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 569-584, January 2026.
Abstract Purpose The emergence of new medications for fatty liver conditions has increased the need for reliable and widely available assessment of MRI proton density fat fraction (MRI–PDFF). Whereas low‐field MRI presents a promising solution, its utilization is challenging due to the low SNR.

Network Neuroscience of Human Multitasking: Local Connections Matter

Human Brain Mapping, Volume 46, Issue 18, 15 December 2025.
Multitasking limitations can be related to how our senses interact in the brain. This study shows that performance costs in multitasking depend on local brain connections—especially between hearing and control areas—rather than broad brain network differences, supporting the idea that sensory overlap drives multitasking difficulties.
