Fig. 7

Thirty-three-year-old male patient, presented with paraesthesia in both upper limbs with motor weakness in right upper limb. a Sagittal T2 WI of the cervical spine and b axial T2 FFE opposite C3-4 level showing C4-5 and C5-6 posterior disc bulges indenting the cord and C3-4 posterior disc herniation with cranial migration with marked cord compression. The cervical cord is thinned and shows bright T2 signal opposite to C3-4 level denoting cord myelopathy. c Color-coded FA map, with multiple ROIs opposite to different disc levels, showing change of the blue color of the cord opposite C3-4 level. d FA values of the whole cord circumference opposite to all the examined cervical discs, showing moderate reduction of FA value of the whole cord circumference opposite to C3-4 level (the most affected disc level) and C4-5 level (the level below the most affected disc) denoting myelopathy. Mild reduction of FA value is seen opposite to C5-6 level as well. e, f FA values of the spinal cord at 3, 6, 9, and 12 o’clock positions opposite to C3-4 disc level, showing the reduction in FA value is more pronounced opposite to 12 o’clock
