Diffusion tensor imaging in cervical spondylotic myelopathy: a review

Area of Science:

• Neurology
• Radiology
• Biomedical Imaging

Background:

• Degenerative spondylotic myelopathy (CSM) is a leading cause of spinal dysfunction and spasticity.
• Conventional MRI is standard for spinal cord evaluation but has limitations in predicting prognosis.
• Microstructural spinal cord changes are key to understanding CSM progression.

Purpose of the Study:

• To review the application of diffusion tensor imaging (DTI) in evaluating cervical spondylotic myelopathy (CSM).
• To explore DTI's role as an imaging biomarker for predicting CSM severity and prognosis.
• To highlight DTI's ability to detect spinal cord microstructural alterations beyond conventional MRI capabilities.

Main Methods:

• Review of current literature on DTI applications in CSM.
• Analysis of DTI's capacity to assess spinal cord microstructure.
• Comparison of DTI findings with conventional MRI in CSM patients.

Main Results:

• DTI allows for the evaluation of microstructural changes in the spinal cord.
• These changes are often undetectable with conventional MRI.
• DTI shows promise as an imaging biomarker for CSM severity and prognosis.

Conclusions:

• Diffusion tensor imaging (DTI) is a valuable tool for assessing spinal cord integrity in CSM.
• DTI provides insights into microstructural changes, improving prognostic capabilities.
• The use of DTI in CSM evaluation can enhance clinical decision-making and patient care.
