Reducing Noise Induced by Cardiac Pulsatility in Brain Maps of R2* and Magnetic Susceptibility Using Tailored k‐space Sampling

open access: yesNMR in Biomedicine, Volume 39, Issue 6, June 2026.
With linear k‐space sampling trajectories, cardiac pulsation leads to MRI signal instabilities that increase the variability (standard deviation, SD) of R2* and QSM maps across repetitions. Here, we propose alternative trajectories that aim to mitigate the impact of cardiac‐induced noise in brain maps of R2* and QSM.

Evaluation of the HALP Score in the Distinction Between Fetal Growth Restriction and Small for Gestational Age

open access: yesReproductive, Female and Child Health, Volume 5, Issue 2, June 2026.
ABSTRACT Objective To assess whether the hemoglobin–albumin–lymphocyte–platelet (HALP) score distinguishes fetal growth restriction (FGR) from small for gestational age (SGA) and its association with composite adverse perinatal outcome (CAPO). Method This retrospective study included 444 singleton pregnancies (214 FGR; 230 SGA) at a tertiary center ...

Life‐Threatening Bradycardia in Anti‐NMDA‐Receptor Encephalitis and a Novel Use for Permanent Pacing

open access: yesAnnals of Clinical and Translational Neurology, Volume 13, Issue 5, Page 1020-1027, May 2026.
ABSTRACT Background Pediatric anti‐NMDA receptor encephalitis (pNMDARE) is an autoantibody‐mediated disorder that can cause severe autonomic dysfunction, including symptomatic bradycardia and asystole. Dysautonomia can last for years, making it very challenging to manage.

Non‐Invasive Multidimensional Capacitive Sensing for In Vivo Traumatic Brain Injury Monitoring

open access: yesAdvanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.
Single‐electrode, multidimensional capacitive sensors noninvasively assess cerebral autoregulation and compliance for traumatic brain injury monitoring. ABSTRACT Traumatic brain injury (TBI) is a major cause of death and disability, but invasive intracranial pressure (ICP) monitoring is risky, and current non‐invasive methods lack the resolution and ...

Age‐Related Low Frequency Amplitude Differences in Resting‐State Blood Oxygenation Level‐Dependent Signal in the Cerebellum

open access: yesHuman Brain Mapping, Volume 47, Issue 7, May 2026.
This study found that fractional amplitude of low frequency fluctuations in cerebellar Crus I/II is significantly greater in older adults as compared to younger adults. The higher amplitude in this region is associated with increased connectivity to cortical regions, and may be characteristic of healthy aging.

Machine Learning–Based Cardiovascular Risk Classification Using Dynamic Time‐Series Features From Carotid Duplex Sonography

open access: yesInternational Journal of Imaging Systems and Technology, Volume 36, Issue 3, May 2026.
ABSTRACT Although carotid duplex sonography provides comprehensive hemodynamic and morphological information, clinical assessments typically rely on limited static features and flow velocity measurements. This study investigated the feasibility of applying machine learning to classify cardiovascular disease (CVD) risk using dynamic arterial time‐series

Pulsatility Assessment of Cerebral Perforating Arteries Using Submillimeter‐Resolution Dual‐VENC Phase‐Contrast MRI at 3T

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1246-1256, May 2026.
ABSTRACT Background Dysfunction of cerebral perforating arteries is a major contributor to cerebral small vessel disease. Developing a reliable MRI technique for assessing cerebral perforating arteries on widely accessible 3T systems would be advantageous.
