Diffusion tensor imaging of white matter pathology in the mouse brain

Area of Science:

• Neuroimaging
• Neuropathology
• Rodent models

Background:

• Diffusion tensor imaging (DTI) is increasingly utilized in preclinical research for neurological diseases.
• White matter pathology is a key feature in many rodent models of neurological disorders.
• Accurate detection of white matter abnormalities is crucial for understanding disease mechanisms.

Purpose of the Study:

• To review the applications of DTI in detecting white matter pathology in the mouse central nervous system (CNS).
• To highlight the utility of DTI in identifying both major and subtle white matter abnormalities.
• To provide technical insights for designing DTI studies in rodent brain and spinal cord.

Main Methods:

• Review of existing literature on DTI applications in rodent models.
• Analysis of DTI's capability in characterizing white matter microstructure.
• Discussion of technical considerations for DTI acquisition and analysis in rodents.

Main Results:

• DTI effectively detects widespread and focal white matter lesions in mouse models.
• Subtle microstructural changes indicative of early pathology can be identified using DTI.
• Specific technical parameters influence the sensitivity and specificity of DTI in rodents.

Conclusions:

• DTI is a valuable non-invasive imaging technique for assessing white matter pathology in rodent models.
• The review provides a foundation for optimizing DTI protocols in preclinical neurological research.
• Understanding DTI's capabilities aids in the development of more effective therapeutic strategies for neurological diseases.
