Generative MR Multitasking With Complex‐Harmonic Cardiac Encoding: Bridging the Gap Between Gated Imaging and Real‐Time Imaging

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2440-2450, November 2026.
ABSTRACT Purpose To develop a unified image reconstruction framework that bridges real‐time and gated cardiac MRI, including quantitative MRI. Methods We introduce generative multitasking, which learns subject‐ and dataset‐specific implicit neural temporal bases from sequence timings and an interpretable latent space for cardiac and respiratory motion.

Perivascular Spaces as Determinants of Amyloid, Tau, and Vascular Biomarker Progression

Annals of Neurology, Volume 100, Issue 4, Page 695-708, October 2026.
Objective Magnetic resonance imaging (MRI)‐visible enlarged perivascular spaces (PVS) are markers of cerebral small vessel disease (SVD) and aging, processes implicated in both neurodegenerative and cerebrovascular pathologies. However, longitudinal positron emission tomography (PET) studies examining PVS as a mechanism underlying Alzheimer's disease ...

Orbitofrontal and Medial Frontal Gray Matter Volumes Are Associated With Hyperactivity Traits in 2548 Nonclinical Adults

Human Brain Mapping, Volume 47, Issue 14, October 1, 2026.
In 2548 nonclinical adults, smaller orbitofrontal and medial frontal cortex gray matter volumes were associated with higher hyperactivity traits (r = −0.07 to −0.08). These small, robust effects, consistent with ENIGMA ADHD findings, suggest frontal structure–trait mapping extends to the nonclinical ADHD continuum.

Aneurysm Volume in the Rabbit Bifurcation Model-Calculation with Cylindric Volume Formula versus Multiplanar Reconstruction-Volumetry in Contrast-Enhanced Magnet Resonance Angiography

, 2012
Background: So far, aneurysm volume was expressed by using aneurysm width and length. Using these parameters received from magnetic resonance angiography (MRA)- maximum intensity projection (MIP) images, volume of aneurysms was estimated using the ...

Performance of Free‐Running Cardiac and Respiratory Motion‐Resolved Whole‐Heart 5D MRI in Congenital Heart Disease Patients Using a Gadolinium Enhanced Fast‐Interrupted Steady‐State Sequence

Journal of Magnetic Resonance Imaging, Volume 64, Issue 4, Page 996-1008, October 2026.
ABSTRACT Background The performance of 5D imaging in CHD has been previously demonstrated using ferumoxytol rather than gadolinium. Purpose To evaluate the performance of gadolinium enhanced 5D MRI relative to 2D and 3D MRI in CHD patients. Study Type Retrospective.

Standardized MRI‐Based Quantification of Epicardial Adipose Tissue Volume: Reproducibility and Agreement With Cardiac Computed Tomography

Journal of Magnetic Resonance Imaging, Volume 64, Issue 4, Page 1052-1063, October 2026.
ABSTRACT Background Epicardial adipose tissue volume (EATV) is increasingly recognized as a cardiometabolic risk marker associated with adverse outcomes. The most established approach for EATV quantification is cardiac computed tomography (CT). MRI offers a radiation‐free alternative allowing simultaneous assessment of myocardial function and tissue ...
