Advanced MRI features of intraventricular inflammatory myofibroblastic tumor: a case report

BMC Neurology, 2022
Background Inflammatory myofibroblastic tumor (IMT) is a rare central nervous system (CNS) tumor. We first report a rare case of IMT in the lateral ventricle and describe the magnetic resonance imaging (MRI) findings of the tumor with an emphasis on the ...

Role of diffusion-weighted MR imaging in discrimination between the intracranial cystic masses

The Egyptian Journal of Radiology and Nuclear Medicine, 2014
Objective: Discriminating pyogenic brain abscesses from cystic or necrotic tumors is sometimes difficult with CT or conventional MR imaging. Diffusion MR imaging is a valuable diagnostic test in cases of intracranial cystic masses. Methods: This work was

Stroke penumbra defined by an MRI-based oxygen challenge technique: 1. validation using [14C]2-deoxyglucose autoradiography [PDF]

, 2011
Accurate identification of ischemic penumbra will improve stroke patient selection for reperfusion therapies and clinical trials. Current magnetic resonance imaging (MRI) techniques have limitations and lack validation.

Development and validation of the automated imaging differentiation in parkinsonism (AID-P): a multicentre machine learning study

The Lancet: Digital Health, 2019
Summary: Background: Development of valid, non-invasive biomarkers for parkinsonian syndromes is crucially needed. We aimed to assess whether non-invasive diffusion-weighted MRI can distinguish between parkinsonian syndromes using an automated imaging ...

Variational denoising of diffusion weighted MRI

Inverse Problems & Imaging, 2009
In this paper, we present a novel variational formulation for restoring high angular resolution diffusion imaging (HARDI) data. The restoration formulation involves smoothing signal measurements over the spherical domain and across the 3D image lattice.

Generating Diffusion MRI scalar maps from T1 weighted images using generative adversarial networks

, 2019
Diffusion magnetic resonance imaging (diffusion MRI) is a non-invasive microstructure assessment technique. Scalar measures, such as FA (fractional anisotropy) and MD (mean diffusivity), quantifying micro-structural tissue properties can be obtained ...
