Traumatic Microhemorrhages Are Not Synonymous With Axonal Injury

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Diffuse axonal injury (DAI) is caused by acceleration‐deceleration forces during trauma that shear white matter tracts. Susceptibility‐weighted MRI (SWI) identifies microbleeds that are considered the radiologic hallmark of DAI and are used in clinical prognostication.

Functional MRI in characterization of cystic renal masses

The Egyptian Journal of Radiology and Nuclear Medicine
Background Contrast-enhanced MRI using the Bosniak classification is the standard imaging approach for evaluating cystic renal masses. Diffusion-weighted imaging (DWI), a functional MRI technique that does not require contrast administration, is not ...

POSSIBILITIES OF DIFFUSION-WEIGHTED MAGNETIC RESONANCE IMAGING IN THE DIAGNOSIS OF SPINAL CORD TUMORS

Вестник рентгенологии и радиологии, 2018
The review analyzes the data of modern literature on main methods for the diagnosis of spinal cord tumors. It reflects the possibilities of using diffusion-weighted MRI (DW-MRI), by constructing the maps of measured diffusion coefficients (ICD) and ...

Regularized Spherical Polar Fourier Diffusion MRI with Optimal Dictionary Learning

, 2013
Compressed Sensing (CS) takes advantage of signal sparsity or compressibility and allows superb signal reconstruction from relatively few measurements. Based on CS theory, a suitable dictionary for sparse representation of the signal is required.

Association of CDKN2A/B Homozygous Deletion and Extent of Resection With Survival of Patients With WHO CNS5 Grade 4 Astrocytoma

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives WHO grade 4 astrocytomas are associated with poor prognosis, and their prognostic factors remain controversial. This study aimed to identify the prognostic factors and develop a management algorithm for these patients. Methods This study retrospectively included 151 CNS5 adult grade 4 astrocytomas from two medical centers.

Post-treatment benign changes versus recurrence in non-lymphoid head and neck malignancies: can diffusion-weighted magnetic resonance imaging end up the diagnostic challenge?

The Egyptian Journal of Radiology and Nuclear Medicine, 2020
Background The aim of this prospective cohort study is to substantiate the added value of diffusion-weighted magnetic resonance imaging (DW-MRI) over conventional MRI assessment in the differentiation between locoregional recurrence/residual tumour and ...
