Fig. 5 45 year old female patient presented with neck pain and EMS grade of 1. a) Showed no obvious altered signal intensity in spinal cord on T2 weighted image. However showed cervical spondylotic changes and disc bulde indenting on theca. b) DTI showed increase in ADC value at C6–C7 level, representing myelopathic change not apprent on conventional T2 weighted images.
