Abnormal functional resting-state networks in ADHD : graph theory and pattern recognition analysis of fMRI data
(2014) [Artigo de periódico]The framework of graph theory provides useful tools for investigating the neural substrates of neuropsychiatric disorders. Graph description measures may be useful as predictor variables in classification procedures. Here, ... -
Adrenal collision tumor : renal carcinoma metastasis within adrenal adenoma
(2015) [Artigo de periódico]Collision tumors are defined as the presence of two contiguous histologically different lesions composed of benign and/or malignant components. They are infrequent entities and have been reported in various organs and ... -
Candidate genes associated with neurological findings in a patient with trisomy 4p16.3 and monosomy 5p15.2
(2020) [Artigo de periódico]In this report, we present a patient with brain alterations and dysmorphic features associated with chromosome duplication seen in 4p16.3 region and chromosomal deletion in a critical region responsible for Cri-du-chat ... -
Cardiac involvement in Erdheim-Chester disease : a case report
(2014) [Artigo de periódico]Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis of unknown etiology characterized by proliferation of lipid-containing foamy histiocytes affecting bones and potentially every organ. There is a ... -
Central nervous system infection : imaging findings suggestive of a fungus as the cause
(2021) [Artigo de periódico]Fungal infections of the central nervous system (CNS) are rare. However, because of the increase in the number of immunocompromised individuals, they have been gaining prominence in the differential diagnosis of CNS ... -

Connectome hubs at resting state in children and adolescents : reproducibility and psychopathological correlation
(2016) [Artigo de periódico]Functional brain hubs are key integrative regions in brain networks. Recently, brain hubs identifiedthrough resting-state fMRI have emerged as interesting targets to increase understanding of the relation-ships between ... -
Cortical volume is inversely correlated with interleukin-6 serum levels in patients with schizophrenia
(2021) [Artigo de periódico]Introduction: It is well established that cortical volume are decreased in patients with schizophrenia. One possible explanation is that the increased pro-inflammatory status in schizophrenia is related to volumetric ... -
Interaction between perceived maternal care, anxiety symptoms, and the neurobehavioral response to palatable foods in adolescents
(2016) [Artigo de periódico]Studies in rodents have shown that early life trauma leads to anxiety, increased stress responses to threatening situations, and modifies food intake in a new environment. However, these associations are still to be tested ... -
MRI-based early diagnosis : a diabetic Charcot spine case report
(2021) [Artigo de periódico]Background: Spinal neuroarthropathy (SNA), also known as Charcot spine, is an uncommon aggressive arthropathy, secondary to loss of proprioceptive and nociceptive feedback from the spine. A diagnosis of SNA is frequently ... -
Neuroimaging adolescents with depression in a middle-income country : feasibility of an fMRI protocol and preliminary results
(2020) [Artigo de periódico]Objective: To test the feasibility and to present preliminary results of a neuroimaging protocol to evaluate adolescent depression in a middle-income setting. Methods: We assessed psychotropic medication-free adolescents ... -
Polygenic risk score for attention-deficit/hyperactivity disorder and brain functional networks segregation in a community-based sample
(2023) [Artigo de periódico]Neuroimaging studies suggest that brain development mechanisms might explain at least some behavioural and cognitive attention-deficit/hyperactivity disorder (ADHD) symptoms. However, the putative mechanisms by which genetic ... -
The central vein sign in multiple sclerosis : a biomarker evaluated on a 3T MRI scanner
(2020) [Artigo de periódico]The central vein sign (CVS) is a promising MRI biomarker in multiple sclerosis (MS). CVS has recently been proposed to improve the accuracy and speed of MS diagnosis. Evidence indicates that the presence of CVS in individual ... -
Vaginal ectopic ureter diagnosed by magnetic resonance imaging in a child with complete transverse vaginal septum and hydrocolpos
(2014) [Artigo de periódico]Ectopic ureter draining into the vagina is a rare cause of urinary incontinence. Some cases have been reported in association with malformations of the genitourinary tract, but very few published cases are associated with ...
