Person injured in collision between other specified motor vehicles (traffic), initial encounter [V87.7XXA], Reason for Study: ^Reason: Evaluate C1, cervical spine History: Fracture C1 Motion artifacts degraded exam quality.Straightening of cervical spine which is non specific. Bony defect on the posterior arch of the C1 is not as conspicuous as CT scan. However, there is no evidence of surrounding edema or soft tissue swelling. Thus, the C1 posterior arch bony defect seen on CT scan represents either chronic fracture with non union or congenital defect.The spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The cord signal is normal. The epidural space, thecal sac, and spinal cord are preserved with no evidence of spinal canal/neural foraminal stenosis, cord compression or myelopathy. C2-C3: no neuroforaminal narrowing or spinal stenosis. C3-C4: no neuroforaminal narrowing or spinal stenosis. C4-C5: no neuroforaminal narrowing or spinal stenosis. C5-C6: no neuroforaminal narrowing or spinal stenosis. C6-C7: no neuroforaminal narrowing or spinal stenosis. C7-T1: no neuroforaminal narrowing or spinal stenosis.
1. No evidence of acute fracture of cervical spine. 2. No abnormal spinal cord signal intensity.3. No evidence of bone marrow edema or surrounding soft tissue swelling around C1 posterior arch bony defect area indicating either chronic fracture with non-union or possible congential defect.
