A Label‐Free Hyperspectral Imaging Device for Ex Vivo Characterization and Grading of Meningioma Tissues

open access: yesJournal of Biophotonics, EarlyView.
HyperProbe1.1 enables rapid, label‐free biochemical mapping of freshly resected meningiomas. By quantifying endogenous biomarkers such as cytochrome c oxidase, hemoglobin derivatives, and lipids, the system reveals molecular signatures consistent with tumor grading and generates spatial maps that visualize metabolic and vascular heterogeneity across ...

Comparison of the SMI Technique and CEUS for the Assessment of Microvasculature in Leiomyosarcoma and Its Clinical Value for Application

open access: yesJournal of Clinical Ultrasound, EarlyView.
SMI and CEUS can clearly reflect the microvascular situation in fibroids and effectively guide the clinical treatment of patients with uterine fibroids, but the effect of SMI is better than that of CEUS in guiding the treatment of patients, which can provide a reference for the selection of clinical treatment programs.

Biomarkers for the estimation of isoproterenol‐induced myocardial infarction: A review of key parameters

open access: yesJournal of Intelligent Medicine, EarlyView.
Abstract The isoproterenol‐induced myocardial infarction model is a well‐established experimental approach for studying cardiac injury and testing potential protective treatments. By overstimulating beta‐adrenergic receptors, this model closely reproduces key features of human heart attacks, including oxidative damage, calcium imbalance, inflammatory ...

Quantitative MRI Values for Atrial and Ventricular Parameters in Altitude‐Dwelling Youth

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The hypoxic environment on the Qinghai Plateau significantly exacerbates myocardial remodeling, with sex/ethnicity‐specific variations in cardiac parameters among local youth. Current cardiac MRI reference values lack data from physiologically adapted populations on this plateau.

Safety of MRI Examinations Under Sedation: A Nationwide Survey in Japan

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background MRI is performed under sedation for patients requiring immobility or for those already sedated for clinical management. Although specialist guidelines advocate for anesthesiologist‐led care, non‐anesthesiologist‐led adult sedation is a common practice worldwide. Furthermore, the increase in risk attributable to sedation has not been

Contrast‐Enhanced MR Fingerprinting With Delta‐Relaxometry: Investigating a New Avenue for Tumor Characterization

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background MRI contrast agents enhance lesion characterization by altering tissue relaxation properties. However, quantitative assessment of contrast enhancement is limited by variability in contrast administration parameters, and lack of efficient and precise contrast concentration independent relaxivity (r1, r2) measurement techniques.
