Magnetization transfer magnetic resonance imaging in the assessment of neurological diseases

Area of Science:

• Neuroimaging
• Quantitative MRI
• White Matter Diseases

Background:

• Conventional MRI detects lesions in CNS diseases (e.g., multiple sclerosis) but cannot quantify tissue damage within or outside these lesions.
• Accurate characterization of tissue damage is crucial for understanding disease progression and heterogeneity.

Purpose of the Study:

• To review the contributions of Magnetization Transfer MRI (MT-MRI) in characterizing and quantifying tissue damage in CNS white matter diseases.
• To highlight MT-MRI's potential to improve in vivo assessment of neurological condition evolution.

Main Methods:

• Magnetization Transfer MRI (MT-MRI) as a quantitative imaging technique.
• Derivation of metrics from MT-MRI to quantify structural changes.
• Application in various central nervous system (CNS) pathologies, particularly multiple sclerosis.

Main Results:

• MT-MRI provides quantitative metrics to assess structural changes within and outside conventional MRI-visible lesions.
• This technique offers a more accurate in vivo picture of CNS pathology heterogeneity.
• MT-MRI enhances the ability to monitor the evolution of neurological conditions.

Conclusions:

• MT-MRI overcomes limitations of conventional MRI by quantifying tissue damage in CNS white matter diseases.
• It provides valuable insights into the nature and extent of pathology.
• MT-MRI is a powerful tool for improving the monitoring of neurological disease progression.
