Brain Imaging01:14

Brain Imaging

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 Stimulation (TMS).

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Imaging Studies II: Positron Emission Tomography and Scintigraphy

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Area of Science:

  • Neuroimaging
  • Psychiatry
  • Computational Neuroscience

Background:

  • Schizophrenia's biological basis remains complex.
  • Structural Magnetic Resonance Imaging (sMRI) offers insights into brain structure.
  • Post-processing techniques are crucial for analyzing sMRI data in psychiatric research.

Purpose of the Study:

  • To translate technical sMRI post-processing terminology into clinically understandable descriptions.
  • To review popular sMRI analysis methods used in schizophrenia research.
  • To highlight the contributions of these methods to understanding schizophrenia's neurobiology.

Main Methods:

  • Overview of common sMRI post-processing techniques.
  • Explanation of region-of-interest (ROI) analysis.
  • Explanation of voxel-based morphometry (VBM).
  • Discussion of computational neuroanatomical analyses.

Main Results:

  • Region-of-interest (ROI) analysis allows precise, hypothesis-driven investigation of specific brain regions but is time-consuming and operator-dependent.
  • Voxel-based morphometry (VBM) offers whole-brain analysis, is operator-independent, and fast, but has limitations in anatomical definition and multiple comparisons.
  • Computational neuroanatomical methods show promise for automatically discriminating schizophrenia patients from healthy controls using sMRI data.

Conclusions:

  • Structural MRI is a valuable tool for understanding schizophrenia's biological underpinnings.
  • sMRI analysis aids in planning targeted interventions, particularly in early-stage schizophrenia.
  • Translating technical sMRI findings into clinical language can improve understanding and application in patient care.
