The Affiliated People’s Hospital of Ningbo University, Ningbo, China
Impact: Integrating transcriptomic, receptor, and connectomic frameworks revealed mitochondrial dysfunction, serotonergic–cholinergic modulation, and an inferior frontal network hub underlying cerebral perfusion abnormalities in methamphetamine dependence, offering mechanistic biomarkers and potential targets for cerebrovascular restoration and addiction treatment .
  Figure 564-01-003.  Toward Personalized Blood-Brain Barrier Imaging: Automated Subject-Specific T2 Mapping for Improved Permeability Analysis
Amnah Mahroo, Matthias Günther, Kamil Uludag

Qihao Zhang, Renjiu Hu, Dominick Romano, Benjamin Weppner, Thanh Nguyen, Pascal Spincemaille , Yi Wang
Weill Cornell Medical College, New York, United States of America
Impact: QTMnet can be coupled into clinical nasopharyngeal carcinoma practice to predict patient progression free survival time after treatment.
  Figure 564-01-006.  Heterogenous increase in regional arterial transit time and artery border zone emergence in childhood with multi-PLD pCASL
Wentao Wu, Ziqin Zhang, Manuel Taso, John Detre, Hao Huang, Minhui Ouyang
Children's Hospital of Philadelphia, Philadelphia, United States of America
Impact: This study novelly characterizes nonuniform ATT increase across arterial territories and identifies their border zones emergence after age 10. The normative ATT patterns may guide age-specific single-PLD pCASL optimization, enhancing rCBF accuracy and detection of perfusion-vulnerable regions in pediatric populations.
  Figure 564-01-007.  In-line calculation for dynamic B0 shimming for improved pseudo-continuous arterial spin labeling at 7 Tesla

Shenzhen Longhua District Central Hospital, Shenzhen, China
Impact: This work demonstrates that GM/WM ratios from DSC-MRI are robust biomarkers across 3T and 5T, enhancing the reproducibility of perfusion studies in multi-center trials and facilitating the clinical integration of ultra-high-field MRI.
  Figure 564-01-009.  Mitigating Inflow Artefacts in 3D Brain PCASL
Felix Horger, Heiko Meyer
Research & Clinical Translation, Magnetic Resonance, Siemens Healthineers AG, Erlangen, Germany
Impact: Our solution benefits clinicians and researchers encountering inflow artefacts in their 3D PCASL implementations. By mitigating these artefacts, the method enhances diagnostic reliability and image interpretability, supporting broader adoption of ASL in both clinical and research settings.
