Imaging‐Based Molecular Characterization of Adult‐Type Diffuse Glioma Using Diffusion and Perfusion MRI in Pre‐ and Post‐Treatment Stage Considering Spatial and Temporal Heterogeneity

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Imaging‐based molecular characterization is important for identifying treatment targets in adult‐type diffuse gliomas. Purpose To assess isocitrate dehydrogenase (IDH) mutation and epidermal growth factor receptor (EGFR) amplification status in primary and recurrent gliomas using diffusion and perfusion MRI, addressing spatial and ...

Brain Tumor Characterization Using Multiple MR Parameters From Multi‐Contrast EPI With Keyhole (GE‐SE EPIK) Including Oxygen Extraction Fraction: A Comparison to O‐(2‐[18F]Fluoroethyl)‐L‐Tyrosine (FET) Positron Emission Tomography

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Tumor characterization and treatment efficacy are associated with tissue hypoxia. MR‐derived oxygen extraction fraction (OEF) may offer valuable tumor insights but depends on multiple measurement parameters, often requiring multiple sequence acquisitions.

Magnetic Resonance Imaging in the Clinical Evaluation of Lung Disorders: Current Status and Future Prospects

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT The low proton density and high signal decay rate of pulmonary tissue have previously hampered the application of magnetic resonance imaging (MRI) in the clinical evaluation of lung disorders. With the continuing technical advances in scanners, coils, pulse sequences, and image postprocessing, pulmonary MRI can provide structural and ...

MR‐Guidance of Gene Therapy for Brain Diseases: Moving From Palliative Treatment to Cures

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Regulatory bodies in the U.S. and Europe recently approved a gene therapy for aromatic L‐amino acid decarboxylase (AADC) deficiency, a rare neurologic disorder where a genetic mutation prevents dopamine production in the brain. Affected children fail to develop normal motor and cognitive functions.
