Cervical Spine Injuries, Fractures and Whiplash - T1-Weighted MR Image

Gadolinium enhanced, T1 weighted MR image
Gadolinium enhanced, T1–weighted MR image from a 31–year–old man who had incessant radiating pain within weeks after a car collision. The large disc protrusion at C5–C6 was rated a Grade 4 because it completely obliterates the combined anterior epidural and subarachnoid spaces and pushes the spinal cord posteriorly against the unyielding lamina and also causes "recoil"–type compression of the spinal cord. The subarachnoid (CSF) compartment is rendered black. The epidural sinusoids are markedly widened by the mass effect of the herniation, also the venous blood flow is obstructed. This venous "pooling" causes the Gadolinium to render a strong (white) signal. Behind C6 a small (black = signal void) artery is seen inside the venous sinus.
