Efficacy and Safety of 60 W Versus 90 W, 4‐s Radiofrequency Applications to the Esophagus‐Adjacent Left Atrial Posterior Wall During Pulmonary Vein Isolation: A Pilot Study

open access: yesJournal of Arrhythmia, Volume 42, Issue 5, October 2026.
In this randomized pilot study, 60 W and 90 W QMODE+ RF applications for the periesophageal region achieved comparable acute block and low esophageal injury rates (4.2% each), with similar 1‐year arrhythmia‐free survival, although contact force was higher in the 60 W group.

Clinical Advantages and Pitfalls of Pulsed Field Ablation: How to Prevent ALH Syndrome

open access: yesJournal of Arrhythmia, Volume 42, Issue 5, October 2026.
Pulsed‐field (PF) Ablation Index (combined with average contact force and number of PF pulses) accurately predicted lesion depth in the prospective validation study. Importantly, no lesion formation was observed in the absence of electrode–tissue contact when the ablation electrode was positioned only 1–2 mm away from the endocardium. ABSTRACT Catheter

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

open access: yesMagnetic 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 ...

A Modified Balanced Steady State Free Precession Sequence for Overhauser Magnetic Resonance Imaging

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 4, Page 1655-1665, October 2026.
ABSTRACT Purpose Low‐ and ultralow‐field magnetic resonance imaging (ULF MRI) have inherently low signal‐to‐noise ratio (SNR) by design. Overhauser dynamic nuclear polarization (ODNP) stands out as an effective solution for continuous signal enhancement.

Laterally Oscillating Trajectory for Undersampling Slices: LOTUS

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 4, Page 1682-1695, October 2026.
ABSTRACT Purpose While spiral sampling offers SNR advantages for diffusion MRI, its acceleration with simultaneous multislice remains relatively unexplored. This study introduces Laterally Oscillating Trajectory for Undersampling Slices (LOTUS), which is a 3D spiral‐like k‐space trajectory that aims to minimize g‐factor via controlled incoherent ...

Design of an 8‐Channel Transmit 32‐Channel Receive 11.7T Head Coil and Evaluation of SNR Gains

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 4, Page 2004-2018, October 2026.
ABSTRACT Purpose To design and develop an 8‐channel transmit 32‐channel receive 11.7T head coil for the strongest human MRI scanner to date, demonstrate safety, and evaluate signal‐to‐noise ratio (SNR) gains compared to 7T, the most used ultra‐high‐field (UHF) platform.
