Thoracic cord magnetic resonance imaging of 71 year old patient in the course of radiation myelitis. a) February 2013: T1-weighted MRI scan without contrast shows hyperintense post-actinic changes in vertebrae Th 8-12, isointense changes in segments Th 7-9 and Th 11 fracture. b) February 2013: T1-weighted MRI with gadolinium demonstrates a ring-shaped posterior enhancement in spinal cord (arrow) at the level of Th 8-9. c) July 2013: T1-weighted MRI with gadolinium demonstrates a decrease of the ring-shaped posterior enhancement in spinal cord (arrow) at the level of Th 8-9 in comparison with the previous study (Figure 1b). d) July 2013: T2-weighted MRI scans demonstrate no signs of edema.
