Purpose To evaluate the white matter integrity of corona radiata, cingulate gyri, and corpus callosum in patients with human immunodeficiency virus (HIV) infection through diffusion tensor imaging (DTI). Materials Methods Thirty‐four at least 5 years HIV 27 healthy controls underwent magnetic resonance (MRI) a 1.5 T scanner. A voxelwise‐based technique was used to analyze DTI data. Results We found that body fractional anisotropy (FA) significantly reduced, whereas mean diffusivity (MD)...
Neurologic complications are being recognized as important outcomes of coronavirus disease 2019 (COVID-19). Pathogenesis is varied and incompletely understood, may include neuroinvasion, indirect post-infectious neuroinflammation, cerebrovascular pathologies. We present a case COVID-19-related encephalomyeloradiculitis with clinical magnetic resonance imaging characteristics neuromyelitis optica spectrum disorders that was associated anti-aquaporin-4 antibodies. Our suggests autoimmunity...
To evaluate whether human immunodeficiency virus (HIV)-positive patients with and without executive functions deficits healthy control subjects differ on cortical thickness subcortical brain structures volume in vivo.In total, 34 HIV-positive were compared 13 19 gender-, age-, education-matched subjects. Executive impairments classified by performance the Wisconsin card sorting test. T1 3-dimensional magnetization prepared rapid gradient echo-weighted imaging was performed using a 1.5 Tesla...
Purpose To longitudinally evaluate the cortical thickness and deep gray matter structures volume, measured from T1 three‐dimensional (3D) Gradient echo‐weighted imaging, white integrity, assessed diffusion tensor imaging (DTI) of HIV‐positive patients. Materials Methods Twenty‐one patients on stable highly active antiretroviral therapy (HAART) with CD4+ T lymphocytes count >200 cells/mL viral load <50 copies/mL underwent two magnetic resonance (MRI) scans a median interval 26.6 months....
Purpose Cognitive dysfunction is common in neuropsychiatric systemic lupus erythematosus (SLE). Memory a commonly affected cognitive domain. Clinically, however, it difficult to detect memory deficits. The objective of this study evaluate whether normal controls and SLE patients with without deficit differ terms white-matter integrity. Methods Twenty were compared 47 22 sex-, age-, education-matched control individuals. Diffusion tensor imaging (DTI) was performed 1.5-Tesla scanner. For...
To report the experience of Brazilian Program Pediatric Teleradiology in combining teleconferencing and a virtual learning environment for services integration, collaborative research, continuing education pediatric radiology.We performed meetings from March 2005 to October 2010 on radiology-related themes, using combination videoconferences Web conferences, which were recorded made available an open-source software (Moodle) reuse.We 58 sessions: 29 anatomical-clinical-radiological sessions,...
Purpose The objectives of this study were to determine if HIV-infected patients treated with highly active antiretroviral therapy (HAART), without dementia, suffer from longitudinal gray matter (GM) volume loss, changes in white (WM) integrity and deterioration functional connectivity at rest, an average interval 30 months. Methods Clinically stable HIV-positive (on HAART, CD4 + T lymphocyte > 200 cells/μl, viral loads <50 copies/μl) recruited. None them had HIV-associated dementia. Each...
<h3>SUMMARY:</h3> Since 2005, it has been known that mother-to-child transmission of the chikungunya virus is possible. Transmission generally occurs in perinatal period. In present study, we describe brain lesions seen on MR imaging 6 cases infection. Patients who underwent acute phase presented with areas restricted diffusion white matter, suggesting a perivascular distribution, whereas those subacute/late showed cystic lesions, also or without atrophy. One patient scattered hemorrhages...
Purpose To determine whether systemic lupus erythematosus (SLE) affecting subcortical white matter volumes, deep gray and cortical thickness differ between groups of SLE patients with psychiatric (P-SLE), neurological (N-SLE), or nonneuropsychiatric (non-NPSLE) presentations. Materials Methods Sixty-seven participants were divided into three (P-SLE [n = 19], N-SLE 12], non-NPSLE 36]) examined a 1.5T MRI scanner. The images segmented in FreeSurfer software volumetric measures using T1 3D...
