Brain Imaging

928
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...

Summary

Diffusion tensor imaging (DTI) offers insights into brain connectivity after traumatic brain injury (TBI). However, current DTI methods are only sensitive to group-level TBI changes, not individual diagnoses.

Area of Science:

  • Neuroimaging
  • Neurology
  • Radiology

Background:

  • Neuroimaging is crucial for diagnosing traumatic brain injury (TBI).
  • Diffusion tensor imaging (DTI) provides detailed information about the brain's structural connectivity (connectome).

Purpose of the Study:

  • To systematically review the role and clinical applications of DTI and advanced diffusion techniques in TBI.
  • To evaluate the effectiveness of DTI in diagnosing TBI at both group and individual levels.

Main Methods:

  • Systematic review of DTI and advanced diffusion imaging literature in the context of TBI.
  • Inclusion of techniques such as diffusion kurtosis imaging (DKI), neurite orientation dispersion and density imaging, diffusion spectrum imaging, and q-ball imaging.

Main Results:

  • DTI techniques have advanced significantly over the past 20 years.
  • Current DTI methods demonstrate sensitivity to TBI at the group level.
  • Insufficient evidence exists to support DTI's role in diagnosing TBI at the individual level.

Conclusions:

  • Despite advancements, DTI's current utility in TBI is limited to group-level analysis.
  • Future research should explore machine learning applications for pattern classification of TBI using DTI data.
