  Figure 665-03-001.  Time-Dependent Diffusion MRI Reveals Microstructural Differences Between Early Progression and Pseudoprogression in Glioma
Junwei Chang, Yuhui Xiong, Jing Zhang
Department of Magnetic Resonance, Lanzhou, China
Impact: This work enables clinicians to non-invasively differentiate true tumor progression from pseudopgression, guiding personalized therapy. It uniquely probes cellular-scale microstructural evolution in vivo, directly impacting patient survival and quality of life.
  Figure 665-03-002.  Altered Brain Function and Clinical Correlations in Non-Neuropsychiatric SLE: A Multimodal Resting-State fMRI Study
Jialing Chen, Haitao Qin, Jinyuan Weng, Ao Feng
Renmin Hospital, Hubei University of Medicine, Shiyan, Hubei Province, Shiyan, China
Impact: Both increased fALFF and ReHo may serve as imaging markers of early brain functional alterations in non-NPSLE, with fALFF demonstrating higher sensitivity and potential efficacy for detecting subtle neural compensatory changes.
  Figure 665-03-003.  Subvoxel Quantitative Susceptibility Decomposition Reveals Distinct Paramagnetic and Diamagnetic Alterations in PD
liu di, Yueluan Jiang, Boyu Chen
The First Hospital of China Medical University, Shenyang, China
Impact: χ-separation decomposes subvoxel magnetic susceptibility sources, enabling in vivo differentiation between iron deposition and myelin alterations in Parkinson’s disease, thereby providing new quantitative biomarkers for neurodegeneration and cognition-related pathophysiology.
  Figure 665-03-004.  fMRI Connectivity-Based Clustering of PVNH to guide SEEG implantation
Justyna Gula, Sem Jordaan, Raf van Hoof, Rutger Slegers, Simon Lamquet, Arne Hostens, Olaf Schijns, Borbála Hunyadi, Jacobus Jansen, Simon Tousseyn
Maastricht University, Maastricht, Netherlands
Impact: Clustering periventricular nodular heterotopia based on connectivity patterns to other brain regions may help guide stereo-EEG (SEEG) implantation planning, ensuring that each cluster and its connected regions are sampled by SEEG to avoid omission of potential epileptogenic areas.
  Figure 665-03-005.  Low frequency fourth ventricle cerebrospinal fluid inflow and vascular reactivity in Cerebral Amyloid Angiopathy
Thijs van Harten, Hilde van den Brink, Leon Munting, Laura Lewis, Steven Greenberg, Mahmut Gurol, Susanne van Veluw
Massachusetts General Hospital, Boston, United States of America
Impact: Visual stimulation-evoked vascular reactivity is impaired in patients with Cerebral Amyloid Angiopathy. It remains unclear whether reduced vascular reactivity is linked to impaired cerebrospinal fluid dynamics. Interrogating this relationship with non-invasive MRI will help with our understanding of these phenomena.
  Figure 665-03-006.  Investigating brain network adaptations to light exercise and perceived effort in Fibromyalgia and Long-COVID
Aneurin Kennerley, Oliver Mundell, Elisa Zamboni, Fabio Zambolin, William Gregory, Jamie McPhee
Manchester Metropolitan University, Manchester, United Kingdom
Impact: This study shows neural inefficiency signatures in FMS and LC, with altered network integration and recovery after mild exertion, offering a potential biomarker for central dysregulation across chronic conditions.
  Figure 665-03-007.  Resting state functional magnetic resonance imaging study comparing tremor-dominant Parkinson’s disease and essential tremor
Yina Lan, Xinyun Liu, Yongqin Xiong, Xin Lou
The First Medical Center, Chinese PLA General Hospital, Beijing, China
Impact: To enhance the understanding of spontaneous brain activity patterns of tremor-dominant Parkinson’s disease (TD) and essential tremor (ET), and to facilitate more effective differentiation between these two conditions
  Figure 665-03-008.  The Amplitude of Low-Frequency Fluctuations is Correlated with Birth Trauma in Patients with Postpartum PTSD
Bo Li, Chunlian Chen, Liping Chai, Daming Shen, Kai Liu, Shufen Zhang
The 960th Hospital of the PLA Joint Logistic Support Force, Jinan, China
Impact: This study identified fetal head descending thrust as an objective predictor for emergency caesarean section and revealed distinct spontaneous neural activity alterations in PP-PTSD patients, providing a novel strategy for preemptive psychological intervention and enhancing the understanding of PP-PTSD neuropathology.
  Figure 665-03-009.  Analysis of risk factors for myocardial injury in patients with acute ischemic stroke and construction of nomogram prediction
Xianwei Liu
Tongren Hospital, Shanghai, China
Impact: The research on the prediction model of myocardial injury has a profound impact on clinical practice, patient prognosis, medical resource allocation, and scientific research transformation by filling the gap in clinical diagnosis, optimizing treatment strategies, and promoting mechanism exploration.
  Figure 665-03-010.  Global functional connectivity is altered in cognitively intact APOE ε4 carriers
Katherine Koenig, Sally Durgerian, Mark Lowe, Frank DiFilippo, Lynn Bekris, James Leverenz, Jagan Pillai, Stephen Rao
Cleveland Clinic, Cleveland, United States of America
Impact: Our findings in a longitudinal sample of cognitively intact APOE ε4 carriers add to the literature on resting state functional connectivity changes in preclinical Alzheimer’s disease. These early changes may point to mechanisms of AD-related cognitive decline.
  Figure 665-03-011.  White Matter and Glymphatic Alterations in DoC: Links to Consciousness and Prognosis
Xiaoyang Ma, Yuhui Xiong, Jing Zhang
Lanzhou University Second Hospital, Lanzhou, China
Impact: TBI may cause brain structural damage, impair glymphatic function, and subsequently affect patients' levels of consciousness. These findings further indicate that glymphatic dysfunction could play an important role in the pathogenesis and prognosis of disorders of consciousness.
  Figure 665-03-012.  Predicting Treatment Response to Transcutaneous Auricular Vagus Nerve Stimulation in Patients with Insomnia
Meng Qi, Yue Zhang, Jun Peng, Bo Liu
The Second Affiliated Hospital of Guangzhou University of Chinese Medicine, Guangzhou, China
Impact: Transcutaneous auricular vagus nerve stimulation (taVNS) may alleviate insomnia by lowering functional connectivity (FC) between salience and task‑positive networks and within the cingulo‑opercular network. Baseline left insula‑visual/auditory FC could predict taVNS treatment response.
  Figure 665-03-013.  Data-Efficient Individualized Eloquent Cortex Localization Using Convolutional Neural Networks in Brain Tumor Patients
Yu Shang, rui deng, yuxia liang, Qinqin Xie, Jin wang, Ming Zhang, chen niu
The First Affiliated Hospital of Xi'an Jiaotong University, Xi'an, China
Impact: This study demonstrated a voxel-level functional mapping method that improved efficiency and accuracy for preoperative brain tumor planning with minimal quantities of rs-fMRI data, offering potential for enhancing clinical workflows, improving patient comfort, and enabling individualized brain tumor treatment planning.
  Figure 665-03-014.  Neurotransmitter Alterations and Glymphatic System Dysfunction in Chronic Insomnia Co-morbid with Major Depressive Disorder
Yongqiong Tao, Lu Han, Peng Wu
Impact: Patients with insomnia and comorbid depression show distinct patterns of glymphatic dysfunction and neurotransmitter imbalance. Coexisting depression may worsen glymphatic impairment, highlighting the need for early intervention and cautious use of GABA receptor agonists in treatment.
