1. Adolescent depression and resting-state fMRI brain networks: a scoping review of longitudinal studies
The neurobiological factors associated with the emergence of major depressive disorder (MDD) in adolescence are still unclear. Previous cross-sectional studies have documented aberrant connectivity in resting-state functional magnetic resonance imaging (rs-fMRI) networks. However, whether these findings precede MDD onset has not been established. This scopin

2. Attention-deficit/hyperactivity disorder and brain metabolites from proton magnetic resonance spectroscopy: a systematic review and meta-analysis protocol
Abstract Despite major advances in the study of the brain, investigations on neurochemistry in vivo still lack the solid ground of more established methods, such as structural and functional magnetic resonance imaging. Proton magnetic resonance spectroscopy (MRS) is a technique that might potentially fill in this gap. Nevertheless, studies using this approac

3. THE EXPLORATORY DIMENSION OF FMRI EXPERIMENTS
Abstract Driven by an appreciation of the field’s early stage of development, I apply the concept of exploratory experimentation, originally put forward in the late 90s philosophy of biology, to current research in cognitive neuroscience. I concentrate on functional magnetic resonance imaging and how this wide-spread technique is used, from experimental de

4. Pelvic floor muscles after prostate radiation therapy: morpho-functional assessment by magnetic resonance imaging, surface electromyography and digital anal palpation
ABSTRACT Aim: To evaluate the radiotherapy (RT) effect in the pelvic floor muscles (PFM) function in men with prostate cancer (PC). Materials and Methods: A cross-sectional study included three groups of patients with PC and RT indication: 1) Pre-RT group: evaluated before the beginning of RT; 2) Acute group: evaluated between six months and one year after

5. Association between poor tolerability of antidepressant treatment and brain functional activation in youth at risk for bipolar disorder
Objective: To investigate whether poor antidepressant tolerability is associated with functional brain changes in children and adolescents of parents with bipolar I disorder (at-risk youth). Methods: Seventy-three at-risk youth (ages 9-20 years old) who participated in a prospective study and had an available baseline functional magnetic resonance imaging

7. Effect of pelvimetric diameters on success of surgery in patients submitted to robot-assisted perineal radical prostatectomy
ABSTRACT Objective: Minimally invasive techniques are used increasingly by virtue of advancements in technology. Surgery for prostate cancer, which has high morbidity, is performed with an increasing momentum based on the successful oncological and functional outcomes as well as cosmetic aspects. Materials and methods: Sixty two patients underwent robot-as

9. Neuroimaging adolescents with depression in a middle-income country: feasibility of an fMRI protocol and preliminary results
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 (age range 14-16 years) with a diagnosis of major depressive disorder (MDD). Participants underwent a comprehensive clinical evaluation a

11. The role of gadoxetic acid-enhanced magnetic resonance cholangiography in the evaluation of postoperative bile duct injury: pictorial essay
Resumo As lesões iatrogênicas das vias biliares são relativamente frequentes e aumentam as taxas de morbidade e mortalidade pós- operatória. A colangiografia por ressonância magnética ponderada em T2 e as imagens hepatobiliares funcionais com ácido gadoxético (CRM-F) são fundamentais na abordagem diagnóstica desses pacientes.

12. Neuropsychology of the temporal lobe: Luria's and contemporary conceptions
RESUMO Atualmente, estudos de lesão cerebral implementam técnicas como tomografia computadorizada, ressonância magnética funcional, tomografia por emissão de fóton e tomografia por emissão de pósitrons. Estudos sobre cognição do neuropsicólogo Alexander Romanovich Luria foram realizados há vários anos sem o uso de tecnologia de imagem, com uma g
