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).

Summary

Transcranial sonography (TCS) aids in diagnosing brain conditions by visualizing structures. This non-invasive technique helps differentiate neurodegenerative diseases, including Parkinson's disease and Huntington's disease.

Area of Science:

  • Neuroimaging
  • Neurology
  • Medical Diagnostics

Background:

  • Transcranial sonography (TCS) utilizes B-mode imaging to visualize both infratentorial and supratentorial brain structures.
  • Its capability makes it a valuable tool for diagnosing and differentiating various intracranial pathologies.

Purpose of the Study:

  • To review the utility of TCS in differentiating neurodegenerative diseases.
  • To explore the role of TCS in identifying specific brain structure echogenicity changes associated with movement disorders.

Main Methods:

  • Review of existing literature on Transcranial Sonography (TCS) applications in neurology.
  • Analysis of TCS findings in patients with parkinsonian syndromes, Parkinson's disease, Huntington's disease, dystonia, Wilson's disease, and parkinson-plus syndromes.

Main Results:

  • TCS can detect characteristic echogenicity changes in the substantia nigra (SN) in Parkinson's disease.
  • Abnormal echogenicity of the caudate nucleus and lentiform nucleus (LN) can be identified in Huntington's disease, dystonia, and Wilson's disease, respectively.
  • TCS may reveal ventricular width alterations in parkinson-plus syndromes and serve as a marker for subclinical nigrostriatal injury.

Conclusions:

  • Transcranial sonography (TCS) is a rapid, safe, and non-invasive neuroimaging method.
  • TCS can assist in differentiating various movement disorders when used in conjunction with clinical assessment and other neuroimaging modalities.
