A multicenter reliability study of extremity-magnetic resonance imaging in the longitudinal evaluation of rheumatoid arthritis.

Factors Associated with Requesting Magnetic Resonance Imaging during the Management of Glomus Tumors

Background: The characteristic clinical presentation of glomus tumors and the low negative predictive value of themagnetic resonance imaging (MRI) raise the question whether MRI improves their management. Therefore, this studyaimed to investigate whether MRI improved the management of glomus tumors.Methods: In total, 87 patients with a histologically confirmed glomus tumor wer...

Effect of Bias in Contrast Agent Concentration Measurement on Estimated Pharmacokinetic Parameters in Brain Dynamic Contrast-Enhanced Magnetic Resonance Imaging Studies

Introduction: Pharmacokinetic (PK) modeling of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is widely applied in tumor diagnosis and treatment evaluation. Precision analysis of the estimated PK parameters is essential when they are used as a measure for therapy evaluation or treatment planning. In this study, the accuracy of PK parameters in brain DCE...

A new low-field extremity magnetic resonance imaging and proposed compact MRI score: evaluation of anti-tumor necrosis factor biologics on rheumatoid arthritis

Magnetic resonance imaging (MRI) is a useful tool for evaluating disease activity and therapeutic efficacy in rheumatoid arthritis (RA). However, conventional whole-body MRI is inconvenient on several levels. We have therefore developed a new low-field extremity MRI (compact MRI, cMRI) and examined its clinical utility. Thirteen RA patients treated with anti-tumor necrosis factor (TNF) biologic...

The Assessment of Toxicity Characteristics of Cellular Uptake of Paramagnetic Nanoparticles as a New Magnetic Resonance Imaging Contrast Agent

Nanoparticles are unique that enable many promising medical and technological applications intheir physical, and chemical properties. It is widely accepted that nanoparticles should bethoroughly tested for health nanotoxicity, but a moderate risk analysis is currently prevented by arevealing absence of mechanistic knowledge of nanoparticle toxicity. The purpose of this study<b...
