Quantifying Cardiac, Respiratory, and Low Frequency Components of CSF Motion From fMRI Inflow Effects

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1916-1928, October 2026.
ABSTRACT Purpose Cerebrospinal fluid (CSF) flow oscillations have emerged as a potentially important marker related to brain clearance, but their acquisition often relies on specialized imaging MRI sequences. The purpose of this work was to enable quantitative assessment of CSF flow associated with cardiac, respiratory, and low‐frequency cycles using ...

Collaborative Reconstruction of PROPELLER‐EPI Data Using POCSMUSE (CORPUSE) for High‐Fidelity Diffusion MRI

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1929-1946, October 2026.
ABSTRACT Purpose To develop a reconstruction framework for DW‐PROPELLER‐EPI that improves image quality and SNR efficiency under per‐blade acceleration while minimizing EPI‐related artifacts, enabling high‐resolution diffusion‐tensor imaging (DTI) with fewer blades.

Multiple‐TE Based Blood–Brain‐Barrier Water Exchange Time Measurement Using a TE‐Resolved 3D TSE Stack‐Of‐Spirals Readout

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1629-1644, October 2026.
ABSTRACT Purpose To develop a slice‐wise blurring‐free and densely sampled TE‐resolved multiple‐TE (mTE) ASL sequence (TASL) for measuring blood–brain barrier (BBB) water exchange time. Methods A 3D TSE spiral‐readout pCASL sequence was modified to enable TE‐resolved acquisition.

Quantifying the Diamagnetic and Paramagnetic Components of Beta‐Amyloid Plaques Using Decomposed Quantitative Susceptibility Mapping in Mouse Models of Alzheimer's Disease

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
Ex vivo MRI was performed on AD mouse models using high‐resolution multi‐echo gradient‐echo imaging on a 9.4T scanner to generate quantitative susceptibility maps (QSM) and separate diamagnetic and paramagnetic components. Amyloid‐β$$ \beta $$ plaques were detected from the susceptibility maps.

Phantom evaluation of small‐pixel effect in ultra‐high‐resolution photon‐counting CT: Noise texture and high‐contrast spatial resolution

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Ultra‐high‐resolution (UHR) photon‐counting CT (PCCT) with small‐pixel detectors improves resolution and noise, but its dependence on diverse imaging conditions remains insufficiently characterized. Purpose To systematically evaluate the small‐pixel effect in UHR PCCT by assessing noise properties and high‐contrast spatial ...
