Journal ArticleDOI
Quantifying brain iron deposition in patients with Parkinson's disease using quantitative susceptibility mapping, R2 and R2.
Jeam Haroldo Oliveira Barbosa,Antonio Carlos dos Santos,Vitor Tumas,Manju Liu,Weili Zheng,E. Mark Haacke,Carlos Ernesto Garrido Salmon +6 more
TL;DR: The QSM map was the most sensitive quantitative technique for detecting a significant increase of iron for PD and the highest significant difference between controls and patients was found in the substantia nigra pars compacta using QSM.
Journal ArticleDOI
Neuro-degeneration profile of Alzheimer's patients: A brain morphometry study
Silvio Ramos Bernardes da Silva Filho,Jeam Haroldo Oliveira Barbosa,Carlo Rondinoni,Antonio Carlos dos Santos,Carlos Ernesto Garrido Salmon,Nereida Kilza da Costa Lima,Eduardo Ferriolli,Julio Cesar Moriguti +7 more
TL;DR: Brain regions affected by AD during its initial stages, such as hippocampus, amygdala, entorhinal cortex, and parahippocampal region, were found to be altered even in individuals with severe AD, and individuals, specifically, with CDR 3, have multiple regions with lower volumes than individuals with a CDR 2.
Journal ArticleDOI
Susceptibility weighted imaging: differentiating between calcification and hemosiderin
TL;DR: The authors highlight that the sigmoid mask allows for contrasting calcifications and hemosiderin on a single SWI image, and compromise the diagnostic reliability.
Journal ArticleDOI
Dextran-Coated Antiferromagnetic MnO Nanoparticles for a T1-MRI Contrast Agent with High Colloidal Stability
Herbert R. Neves,Rafael A. Bini,Jeam Haroldo Oliveira Barbosa,Carlos Ernesto Garrido Salmon,Laudemir Carlos Varanda +4 more
TL;DR: In this article, a simple approach to synthesize carboxymethyl dextran-coated MnO nanoparticles (CMDex-MnONPs) with high colloidal stability in physiological saline solutions is described for potential applications as a magnetic resonance imaging (MRI) T1 contrast agent.
