Brain Imaging

1.0K
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Area of Science:

  • Neurology
  • Neuroscience
  • Pain Research

Background:

  • Cluster headache is a rare primary headache disorder and the most common trigeminal-autonomic cephalalgia.
  • Its pathophysiology remains poorly understood despite extensive research.
  • Cerebral imaging has become crucial in investigating pain and headache disorders.

Purpose of the Study:

  • To investigate the pathophysiology of cluster headache using advanced neuroimaging techniques.
  • To explore structural brain changes associated with cluster headache.
  • To understand the dynamic nature of these changes over the disease course.

Main Methods:

  • Magnetic resonance-based, voxel-based morphometry (VBM) was employed.
  • Analysis focused on identifying grey matter changes in brain structures.
  • Longitudinal assessment of structural changes was considered.

Main Results:

  • Pioneering studies identified increased grey matter in the posterior hypothalamus.
  • Recent research reveals structural changes in multiple brain areas involved in pain processing, sensory integration, and emotional evaluation.
  • These structural changes are dynamic and vary with disease progression.

Conclusions:

  • The findings suggest brain plasticity plays a role in cluster headache.
  • A complex pathophysiological model involving a maladaptive pain modulatory network is proposed.
  • Future research should focus on these dynamic network alterations.
