Quantification of ischemic brain edema after mechanical thrombectomy using dual-energy computed tomography in patients with ischemic stroke

Scientific Reports
Net water uptake (NWU) is a quantitative imaging biomarker used to assess cerebral edema resulting from ischemia via Computed Tomography (CT)-densitometry. It serves as a strong predictor of clinical outcome.

Intraoral Coil Arrays for Single‐Tooth Dental MRI

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1858-1865, March 2026.
ABSTRACT Purpose MRI offers superior contrast to x‐ray and CBCT that can play an important role in diagnosing dental pathologies. Current extraoral RF coils for MRI in dentistry provide only limited SNR, thus limiting spatial resolution. We propose an intraoral coil (IOC) array that can provide high SNR to achieve a 250 μm isotropic resolution and ...

Temporal dynamics of white matter hyperintensities related to Alzheimer's disease in adults with Down syndrome

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION White matter hyperintensities (WMH) are common in Down syndrome (DS), yet their longitudinal evolution and associations with Alzheimer's disease (AD) remain unclear. METHODS Longitudinal MRI study, including 80 DS adults and 53 euploid controls. WMH were segmented on serial FLAIR using a longitudinal pipeline.

An Integrated QSM‐Radiomics Nomogram With Clinical and Imaging Markers for Stratifying Cognitive Impairment in Hypertension

CNS Neuroscience &Therapeutics, Volume 32, Issue 2, February 2026.
This study developed an integrated nomogram combining QSM‐based radiomics, brain iron deposition, white matter hyperintensity, and clinical markers. This model demonstrated superior performance in stratifying hypertensive cognitive impairment compared to traditional single‐parameter models.

Ruptured Brain Aneurysm: A Rare Cause Of Isolated Acute Subdural Hematoma

Journal of the Belgian Society of Radiology
Teaching point: Although computed tomography (CT) is the diagnostic gold standard for acute subdural hematoma, the absence of clear trauma should prompt the use of computed tomography angiography (CTA) to identify potential underlying causes, such as ...

The Role of MRI in Debunking the Fallacy of “Mild” Traumatic Brain Injury

Journal of Magnetic Resonance Imaging, Volume 63, Issue 2, Page 297-309, February 2026.
ABSTRACT Mild traumatic brain injury (mTBI) is a prevalent yet often overlooked public health concern due to the absence of detectable abnormalities on CT or conventional MRI scans. Approximately 18.3%–31.3% of mTBI patients experience persistent symptoms 3–6 months post‐injury, despite normal imaging results, making diagnosis and treatment challenging.
