Short-interval follow-up cervical MR imaging of a 67-year-old male ASIA A patient with SCI. T2-weighted FSE images were obtained from an initial MR imaging examination performed 9.5 hours after injury (A and C), as well as from a follow-up postreduction examination performed 55 hours after the first MR imaging (B and D). Demonstrated on the sagittal images (A and B) is a large increase in T2-hyperintense spinal cord edema (arrows demonstrate cranial-most extent), whereas representative axial images from the C5/C6 interspace (C and D) confirm the absence of cord edema at that level on the initial study, with the development of cord edema (arrow) on the second study.
