Diffusion Weighted Imaging [PDF]

, 2020
Diffusion-weighted imaging (DWI) enables the MRI visualization of molecular movements of water in biological tissues. Molecular diffusion in vivo reflects interactions with macromolecules, fibres and membranes. Water molecule diffusion patterns can therefore reveal microscopic details about tissue architecture that cannot be appreciated otherwise.

Stroke with unknown time of symptom onset: baseline clinical and magnetic resonance imaging data of the first thousand patients in WAKE-UP (efficacy and safety of mri-based thrombolysis in wake-up stroke: a randomized, doubleblind, placebo-controlled trial) [PDF]

, 2017
Background and Purpose—We describe clinical and magnetic resonance imaging (MRI) characteristics of stroke patients with unknown time of symptom onset potentially eligible for thrombolysis from a large prospective cohort.

Machine learning-based classification of chronic traumatic brain injury using hybrid diffusion imaging

Frontiers in Neuroscience, 2023
Background and purposeTraumatic brain injury (TBI) can cause progressive neuropathology that leads to chronic impairments, creating a need for biomarkers to detect and monitor this condition to improve outcomes. This study aimed to analyze the ability of

MRI in multiple myeloma : a pictorial review of diagnostic and post-treatment findings [PDF]

, 2016
Magnetic resonance imaging (MRI) is increasingly being used in the diagnostic work-up of patients with multiple myeloma. Since 2014, MRI findings are included in the new diagnostic criteria proposed by the International Myeloma Working Group.

Computed diffusion weighted imaging (cDWI) and voxelwise-computed diffusion weighted imaging (vcDWI) for oncologic liver imaging: A pilot study

European Journal of Radiology Open, 2018
Objective: Aim of the study was to evaluate the influence of the selection of measured b-values on the precision of cDWI in the upper abdomen as well as on the lesion contrast of PET-positive liver metastases in cDWI and vcDWI.

Diffusion tensor model links to neurite orientation dispersion and density imaging at high b-value in cerebral cortical gray matter [PDF]

, 2019
Diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI) are widely used models to infer microstructural features in the brain from diffusion-weighted MRI. Several studies have recently applied both models to increase
