Objectives: Goal: to assess fMRI activation during semantic tasks in adolescents with ASD.
Methods: Material: 44 right-handed male adolescents aged 12-19 (mean 14.3 ± 2.
Objectives: Goal: to evaluate changes in the grey matter volume using the VBM method in a group of adolescents with ASD, who met the criteria for Asperger's Syndrome.
Methods: Material and methods: Morphometric evaluations based on Voxel Based Morphometry (VBM) were performed on 37 male adolescents aged 12 to 19 (M = 14.3 ± 2.
Article Synopsis
- Study focused on evaluating the brain's subcortical structures in patients with digestive diseases like functional dyspepsia (FD), irritable bowel syndrome (IBS), and inflammatory bowel diseases (IBD) compared to healthy controls.
- Analysis involved 57 patients (18 with FD, 20 with IBS, and 19 with IBD) and 19 healthy individuals, all scanned using a 3T MRI.
- Results showed that IBD patients had smaller volumes in the left and right thalamus compared to the control group, suggesting that inflammation may contribute to psychological issues like depression and the need for treatments addressing both IBD and mental health.
Purpose: To verify which of the diagnostic modalities: Voiding cystouretrography (VCUG), Sonouretrography (SUG) or Magnetic resonance uretrography (MRU) is the most accurate in the assessment of urethral strictures in males and in what cases the application of novel imaging techniques benefits most.
Methods: 55 male patients with a diagnosis of urethral stricture, were enrolled in this prospective study. Initial diagnosis of urethral stricture was based on anamnesis, uroflowmetry and VCUG.
Article Synopsis
- * Researchers hypothesize that disruptions in axonal connections contribute to the symptoms of these diseases and aim to identify the neuronal networks involved.
- * The findings reveal that patients show additional DMN activity in specific brain regions (like the left superior frontal gyrus) compared to healthy individuals, suggesting altered processing of bodily signals in those with these digestive disorders.
Article Synopsis
- Functional brain imaging techniques like PET and fMRI have enhanced our understanding of the brain's interaction with the digestive system and the mechanisms behind visceral hypersensitivity.
- Studies reveal that psychological factors significantly impact visceral sensitivity, especially in conditions like functional dyspepsia and irritable bowel syndrome.
- The brain-gut axis (BGA) includes various pathways (neuronal, neuroendocrine, neuroimmunological) that show how mental stress can lead to digestive issues by affecting the central nervous system.
We organized 10Kin1day, a pop-up scientific event with the goal to bring together neuroimaging groups from around the world to jointly analyze 10,000+ existing MRI connectivity datasets during a 3-day workshop. In this report, we describe the motivation and principles of 10Kin1day, together with a public release of 8,000+ MRI connectome maps of the human brain.

Yet, our understanding of the interrelationship between these factors is still limited. The study aimed at evaluating patterns of changes in diffusion parameters (as assessed by quantitative diffusion fiber tracking - qDTI) following both aging, and hypertension, as well as the nature of their linkage.

Forty-six older healthy subjects (37 women, 9 men) over 60 years of age were included in the study. The participants were examined on 3.
View Article and Find Full Text PDFThe use of the diffusion tensor imaging (DTI) is rapidly growing in the neuroimaging field. Nevertheless, rigorously performed quantitative validation of DTI pathologic metrics remains very limited owing to the difficulty in co-registering quantitative histology findings with magnetic resonance imaging. The aim of this review is to summarize the existing state-of-the-art knowledge with respect to axial (λ) and radial (λ) diffusivity as DTI markers of axonal and myelin damage, respectively.

Methods: Two groups of 20 patients took part in MRI examinations. This article reports the results of functional MRI during a Stroop color interference task and structural evaluations based on a modified Fazekas scale.
Background: Since introduction of multislice CT scanners into clinical practice, virtual brochoscopy has gained a lot of quality and diagnostic potential. Nevertheless it does not have established place in diagnostics of tracheal and bronchi disorders and its potential has not been examined enough. Nowadays a majority of bronchial tree variants and lesions are revealed by bronchofiberoscopy, which is an objective and a relatively safe method, but has side effects, especially in higher-risk subjects.
View Article and Find Full Text PDFIntroduction: Processing of auditory information in central nervous system bases on the series of quickly occurring neural processes that cannot be separately monitored using only the fMRI registration. Simultaneous recording of the auditory evoked potentials, characterized by good temporal resolution, and the functional magnetic resonance imaging with excellent spatial resolution allows studying higher auditory functions with precision both in time and space.
The Aim Of The Study: was to implement the simultaneous AEP-fMRI recordings method for the investigation of information processing at different levels of central auditory system.
