Due to the effect of the cerebrospinal fluid, the surrounding fat and the thin structure of the spinal cord, routine T2w-TSE imaging of the spinal cord is limited, with a high chance of missed diagnosis or misdiagnosis. This study compared the imaging of DIR and T2w in demyelinating disease to find out which one has a higher diagnostic value. The results demonstrates that SPACE-DIR has significantly higher CNR and found more lesion than T2-TSE in detecting lesion in cervical and thoracic cord for demyelinating disease diagnosis.
