In vivo evolution of biopsy‐proven inflammatory demyelination quantified by R2t* mapping

open access: yesAnnals of Clinical and Translational Neurology, 2020
A 35‐year‐old man with an enhancing tumefactive brain lesion underwent biopsy, revealing inflammatory demyelination. We used quantitative Gradient‐Recalled‐Echo (qGRE) MRI to visualize and measure tissue damage in the lesion. Two weeks after biopsy, qGRE

T2-fluid attenuated inversion recovery mismatch in tumefactive multiple sclerosis.

open access: yes, 2023
The T2-fluid attenuated inversion recovery (FLAIR) mismatch sign has been suggested as an imaging marker of isocitrate dehydrogenase-mutant 1p/19q non-codeleted gliomas with 100% specificity.

Optic Neuritis in the Puerperium Mimicking Severe Preeclampsia: A Neurological Differential Diagnosis in the Obstetric Emergency Setting

open access: yesClinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Optic neuritis is an acute inflammatory disease that can cause acute visual loss. We present a case of a 22‐year‐old female in postpartum with acute headache, retroocular pain, and bilateral amaurosis. Orbit MRI revealed inflammatory changes in both neurovascular optical bundles.

Mutation in RNF170 Causes Unsteady Gait with Hypertrophic Olivary Degeneration

open access: yesClinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Hypertrophic olivary degeneration (HOD) is a rare form of transsynaptic degeneration resulting from disruption of the Guillain–Mollaret triangle, typically presenting with palatal tremor, ataxia, and nystagmus. Mutations in the Ring Finger Protein 170 (RNF170) gene have been associated with autosomal dominant sensory ataxia.

Clinical Applications of Electrical Conductivity Imaging Using MRI

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1224-1245, May 2026.
ABSTRACT Magnetic resonance imaging (MRI) has emerged as a noninvasive technique for probing the electrical properties of biological tissues: electrical conductivity and relative permittivity. This review focuses on the electrical conductivity and provides a comprehensive overview of applications across both low‐ and high‐frequency regimes.
