Evaluation of Partial Volume Correction Techniques for Sodium MRI of the Achilles Tendon

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2180-2193, April 2026.
ABSTRACT Purpose To evaluate partial volume correction (PVC) techniques for sodium MRI of the Achilles tendon in situ and in vivo. Methods Five PVC methods were evaluated including a volume ratio of the proton and sodium segmentations (PSSR), a modified least trimmed square (3D‐mLTS) linear regression, a geometric transfer matrix (GTM) approach, a ...

Doppel as an early‐stage biomarker promoting EMT and dissemination in ovarian cancers

International Journal of Cancer, Volume 158, Issue 6, Page 1755-1768, 15 March 2026.
What's new? Existing biomarkers for ovarian cancer (OC) lack the sensitivity and specificity needed to consistently distinguish the malignancy from non‐ovarian influences and other cancers. Here, the authors explored the ability of the prion‐like protein Doppel, normally found in the male testes, to detect OC.

Gadolinium Pollution—A Future Forward Perspective on Human and Environmental Impact

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1660-1670, March 2026.
ABSTRACT The widespread use of gadolinium‐based contrast agents (GBCAs) in magnetic resonance imaging (MRI) has been instrumental in enhancing diagnostic capabilities. However, the potential environmental and human health impacts of gadolinium pollution have become a growing concern.

Choroid plexus alterations in long COVID and their associations with Alzheimer's disease risks

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Choroid plexus (ChP) enlargement is a neuroimaging biomarker of neuroinflammation and neurodegeneration. However, evidence of ChP structural and perfusion alterations in long coronavirus disease (COVID) and their clinical relevance remains limited.

Adipocyte fatty acid‐binding protein as a cerebrospinal fluid–accessible biomarker and druggable target in subarachnoid haemorrhage: Linking fatty acid dysregulation to microglial neuroinflammation

Clinical and Translational Medicine, Volume 16, Issue 2, February 2026.
A‐FABP mediates neuroinflammation and exaggerates SAH outcomes: In response to SAH, elevated A‐FABP combines with fatty acids to promote microglia activation via the JAK2/STAT3 pathway, while simultaneously disrupting fatty acid metabolism. These dual effects exacerbate neuroinflammation and neurological deterioration, thereby contributing to adverse ...

Technologies and Strategies for Metabolic and Molecular Imaging With Hyperpolarized MRI

Journal of Magnetic Resonance Imaging, Volume 63, Issue 2, Page 310-327, February 2026.
ABSTRACT Conventional Magnetic Resonance Imaging (MRI) offers limited sensitivity for direct metabolic and molecular imaging using non‐proton nuclei due to low thermal nuclear spin polarization. Hyperpolarization (HP) technologies increase nuclear spin polarization by several orders of magnitude, overcoming this limitation to enable in vivo studies of ...

Arterial Spin Labeling en epilepsia

, 2014
In the following report, functional Magnetic Resonance images obtained with the Arterial Spin Labeling tecnique are used to study the cerebral blood perfusion in a epileptic group of patients versus a control group. In order to calibrate and normalize these images, structural MR images (T1) have been used.
