The road to breast cancer screening with diffusion MRI

Frontiers in Oncology, 2023
Breast cancer is the leading cause of cancer in women with a huge medical, social and economic impact. Mammography (MMG) has been the gold standard method until now because it is relatively inexpensive and widely available.

Searching for the neurite density with diffusion MRI: Challenges for biophysical modeling [PDF]

Human Brain Mapping, 2018
In vivo mapping of the neurite density with diffusion MRI (dMRI) is a high but challenging aim. First, it is unknown whether all neurites exhibit completely anisotropic (“stick‐like”) diffusion.

Microstructural parameter estimation in vivo using diffusion MRI and structured prior information. [PDF]

, 2016
Diffusion MRI has recently been used with detailed models to probe tissue microstructure. Much of this work has been performed ex vivo with powerful scanner hardware, to gain sensitivity to parameters such as axon radius.

Translating Muscle RNAseq Into the Clinic for the Diagnosis of Muscle Diseases

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Approximately half of patients with hereditary myopathies remain without a definitive genetic diagnosis after DNA next‐generation sequencing (NGS). Here, we implemented transcriptome analysis of muscle biopsies as a complementary diagnostic tool for patients with muscle disease but no definitive genetic diagnosis after exome ...

The Relationship between the Improvement Level in Blood Gas Parameters in Time and Brain MRI Findings in Newborns with the Diagnosis of Hypoxic Ischemic Encephalopathy

Turkish Archives of Pediatrics
Objective: In this study, we aimed to evaluate the relationship between the level of improvement in blood gas parameters in the first hours of age and normal and diffusion-restriction brain magnetic resonance imaging (MRI).

Brain Characteristics in Patients With Myelin Oligodendrocyte Glycoprotein Antibody‐Associated Disorder by 7.0 Tesla MRI

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Myelin oligodendrocyte glycoprotein antibody‐associated disease (MOGAD) can radiographically mimic multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD). The disease hallmarks cortical lesion, central vein sign (CVS) and paramagnetic rim lesions identified in MS have not yet been comprehensively investigated in ...

An Analysis for IDH‐Mutant Grade 4 Astrocytoma Based on WHO CNS 5: Implication of Clinical Practice

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Purpose There is ongoing debate regarding the therapeutic approach and prognosis for IDH‐mutant grade 4 astrocytoma, a newly defined subtype of diffuse glioma in the 2021 WHO classification system for central nervous system tumors (WHO CNS 5). The aim of this study was to explore the clinical outcome and prognosticators for newly diagnosed IDH‐
