The value of dynamic contrast-enhanced MRI in differentiating triple-negative breast cancer from other subtypes

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine, 2019
Background Breast cancer is a broad spectrum disease, including tumors showing different clinical, pathologic, molecular, and imaging features. Triple-negative breast cancer (TNBC) has an extra aggressive clinical course and poor prognosis being ...

CSF Cytokine Network Organization Predicts Progression Independent of Relapse and MRI Activity in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Progression independent of relapse activity is a major determinant of long‐term disability in multiple sclerosis, but its immunopathologic basis remains incompletely understood. We investigated whether relapse‐independent progression in radiologically stable relapsing–remitting multiple sclerosis is associated with distinct ...

De-enhancing the Dynamic Contrast-Enhanced Breast MRI for Robust Registration [PDF]

open access: yes, 2007
Dynamic enhancement causes serious problems for registration of contrast enhanced breast MRI, due to variable uptakes of agent on different tissues or even same tissues in the breast. We present an iterative optimization algorithm to de-enhance the dynamic contrast-enhanced breast MRI and then register them for avoiding the effects of enhancement on ...

Metabolic and Fluid Biomarkers Support Microglia Activation in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Amyotrophic lateral sclerosis is an incurable neurodegenerative disease involving motor neuron degeneration and metabolic and immune dysfunction. We combined clinical data, cerebrospinal fluid biomarkers and fluorodeoxyglucose positron emission tomography with magnetic resonance imaging to investigate the role of reactive microglia in disease ...

Prostate carcinoma: Accuracy of diagnosis and differentiation with Dynamic Contrast-Enhanced MRI and Diffusion Weighted Imaging

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine, 2015
Background: Diffusion weighted image (DWI) and dynamic contrast enhanced MR imaging (DCE-MRI) provide excellent parameters that are useful for differentiating cancer from normal tissue in prostatic cancer patients. Purpose: To define the diagnostic value

Utility of the APE2 Score as a Diagnostic Tool for Autoimmune Encephalitis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To retrospectively evaluate the diagnostic performance of the Antibody Prevalence in Epilepsy and Encephalopathy (APE2) score relative to clinician‐adjudicated autoimmune encephalitis (AE) and the Graus criteria in a tertiary neuroimmunology referral cohort, including antibody‐negative AE.

Biparametric Prostate MRI: Diagnostic Performance, Estimated Additional Cost of DCE, and Gadolinium Avoidance

open access: yesJournal of Imaging
Biparametric MRI, which excludes dynamic contrast-enhanced imaging, may reduce the resources required for prostate MRI. This exploratory study assessed biparametric MRI findings against biopsy histopathology in a selected cohort and described differences

Cerebrospinal Fluid Over Plasma Links Analytes to Cognitive Decline in Older Adults at Risk for Alzheimer's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To identify inflammatory analytes in cerebrospinal fluid (CSF) and plasma associated with cognitive decline in cognitively normal (CN) older adults at risk for Alzheimer's disease (AD). Methods In a longitudinal study of 118 CN older adults (65–80 years, 54% APOE ε4, 26% preclinical AD), 1331 CSF and 1501 plasma analytes were ...

Statistical analysis of pharmacokinetic models in dynamic contrast-enhanced magnetic resonance imaging.

open access: yes, 2005
This paper assesses the estimation of kinetic parameters from dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Asymptotic results from likelihood-based nonlinear regression are compared with results derived from the posterior distribution ...

Diffusion Basis Spectrum Imaging of Tissue Microstructure and Early Treatment in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Conventional MRI cannot resolve the coexisting pathological processes within multiple sclerosis tissue. Diffusion Basis Spectrum Imaging decomposes the diffusion signal into fiber, cell, and hindered ratios indexing axonal integrity, cellularity, and extracellular space, respectively.
